Physaria kingii is a species of flowering plant in the mustard family known by the common name King bladderpod. It is native to western North America from Utah to Baja California, where it grows in dry and rocky habitat, such as deserts and adjacent mountain slopes. This is a perennial herb growing a small, hairy stem from a caudex. The leaves form a patch or rosette around the caudex, each up to 6 centimeters long and round, oval, diamond, or spoonlike in shape. The inflorescence is an erect or mostly upright raceme of bright yellow mustardlike flowers. The fruit is a hairy capsule under a centimeter long suspended on a short, often curvy pedicel.There are three subspecies. One, the San Bernardino Mountains bladderpod (ssp. bernardina), is a very rare plant known from only a few spots near Big Bear in the San Bernardino Mountains of southern California. Because of threats to the plant from mining and other human activities, this subspecies is treated as an endangered species on the federal level.

Physcion(e)

Physalins are steroidal constituents of Physalis plants which possess an unusual 13,14-seco-16,24-cyclo-steroidal ring skeleton (where the bond that is normally present between the 13 and 14 positions in other steroids is broken while a new bond between positions 16 and 24 is formed; see figure below). Since the isolation and the structure determination of Physalin A and Physalin B in 1969, more than a dozen Physalins were isolated from Physalis species, Physalis alkekengi, Physalis angulata, and Physalis lancifolia. These compounds have antimicrobial, and antiparasitic effects.

Physalaemus santafecinus

Physaria pallida (syn. Lesquerella pallida) is a rare species of flowering plant in the mustard family known by the common name white bladderpod. It is endemic to Texas in the United States, where it is known only from San Augustine County. It is federally listed as an endangered species.This is an annual herb growing mostly erect to a height of 30 to 60 centimeters. The leaves may be any of a variety of shapes and have smooth, toothed, or lobed edges. The longest near the base of the plant can reach 10 centimeters in length. The inflorescence is a raceme of flowers with oval white petals that narrow near the yellowish bases and measure just over a centimeter long. The fruit is a spherical silique which is variable in size.This plant was discovered in the 1830s but not seen again until its rediscovery in 1981. It has never been found outside of San Augustine County, Texas. There are six populations. The plant grows on openings in oak, hickory, and pine woods. It is limited to a part of the Piney Woods region on the Gulf Coastal Plain where there is alkaline soil derived from the Weches Formation. This geologic formation contains carbonates above a layer of water-impermeable glauconite, which keeps the soil above from draining, leaving the area quite moist. Most of the soils in eastern Texas are acidic, but the calcium and magnesium minerals in this formation make it alkaline. Other rare plants that occur on the Weches Formation include Sedum pulchellum, Calylophus drummondianus, Liatris mucronata, Paronychia virginica, Petalostemum pulcherrimum, Heliotropium tenellum, Eleocharis compressa, and Cuphea viscosissima.This plant is threatened by the loss and degradation of its habitat, which has largely been converted to agricultural and pasture use and dug up during gravel mining operations. Glauconite gravel is used for road surfacing. The ecological succession of brush and woody vegetation into the clearings on which it depends also threatens the plant. It does not tolerate competition with other plants. Habitat conservation activities include the removal of brush and vegetation buildup by mechanical means or with herbicides or fire. Most of the populations occur on private property, so conservation will depend on the cooperation of landowners.

Physcomitrium is a genus of mosses, commonly called urn moss, that includes about 80 species and has a cosmopolitan distribution. The scientific name comes from the Ancient Greek words physa, meaning bladder, and mitrion, meaning little turban, which together refer to the urn-like calyptra. The common name is derived from its symmetrical, erect and urn-like capsules that lack peristomes, these features characterising the genus. They are commonly found on exposed soils that are often associated with locations that become very wet in the spring, such as along river banks or on alluvial mud. They occur from near sea level to about 2500 metres. The capsules mature over the winter and into the spring.Many species were once circumscribed within the species Physcomitrium pyriforme, which over time has been broken up into many separate species based on variation of the sporophyte and gametophyte.

Although these organisms look like a single multicellular organism, each specimen is actually a colony of minute organisms called zooids that have to work together for survival. A gas-filled bladder resembling a blue bottle provides buoyancy, and long tentacles of venomous cnidocytes provide a means of capturing prey. A sail on the float, which may be left or right-handed, propels Physalia about the sea, often in groups. These siphonophores sometimes become stranded on beaches, where their toxic nematocysts can remain potent for weeks or months in moist conditions. Both species of this siphonophore resemble a jellyfish in appearance, with their gas-filled float and cluster of polyps beneath, which can hang up to 30 or 165 feet below the surface of the sea.The species Physalia utriculus is given the common name Pacific man o' war to distinguish it from the more widely distributed and larger Physalia physalis, the Portuguese man o' war. The species are told apart by the size of the float (six inches compared to twelve) and by having a single versus several long fishing tentacles. No fatalities from envenomation are recorded for P. utriculus, in contrast to the larger species.Because it frequently washes up on beaches on the coast of the Atlantic, Indian and Pacific Oceans and is seen in the open ocean, Physalia is the best-known species of siphonophore, as nearly all siphonophores live in the cold, dark ocean depths where they can only be observed in their natural habitat by a submersible or ROV.The genus was first described by Jean-Baptiste Lamarck in 1801.

Physcia caesia, known colloquially as blue-gray rosette lichen and powder-back lichen, is a species of foliose lichenized fungus. First described by Georg Franz Hoffmann in 1784, it is common across much of Europe, North America and New Zealand, and more patchily distributed in South America, Asia, Australia and Antarctica. There are 2 subspecies, P. c. caesia and P. c. ventosa, as well as a number of distinct forms and varieties. Molecular studies suggest that the species as currently defined may be polyphyletic. It is typically pale gray shading to darker gray in the center (though some forms are considerably darker), and grows in a small rosette, usually some 2–3 cm (0.79–1.18 in) across at maturity. It only rarely has apothecia, instead reproducing most often vegetatively via soredia, which are piled in round blue-gray mounds across the thallus's upper surface. It grows most often on rock—principally calcareous, but also basaltic and siliceous—and also occurs on bone, bark and soil. It is nitrophilic and is particularly common on substrates where birds perch.Capable of growing at a multitude of angles on a variety of surfaces, Physcia caesia also tolerates a wide range of environmental extremes from the high temperatures of desert locations to the low temperatures of the Antarctic. It grows on both dry stone and that moistened by seepage, and can survive being irregularly submerged for extended periods underwater. Like many lichens that grow on rock, Physcia caesia is able to extract nutrients from the substrate upon which it grows, as well as from rainwater and atmospheric dust. It is threatened by habitat loss through development, as well as trampling or overgrowth of its location. A number of lichenicolous species are known parasites.

Physalospora is a genus of fungi in the family Hyponectriaceae. The genus is estimated to contain about 36 species that grow on dead leaves. Often confused with Botryosphaeria, Physalospora is probably polyphyletic.

Physaria congesta

Physaria obcordata is a rare species of flowering plant in the mustard family known by the common name Dudley Bluffs twinpod. It is similar in appearance to the more common Piceance twinpod, but can be distinguished by looking at the leaves through a hand lens. The Piceance twinpod, Physaria acutifolia has stellate hairs when viewed through a hand lens while Physaria ocordata has markings that look like a satellite dish, or a circle with a dot in the middle. It is endemic to Colorado, where it is found only in the Piceance Basin in Rio Blanco County. It is threatened by the loss and degradation of its habitat. It is a federally listed threatened species of the United States.This plant was discovered in 1982 and described to science in 1983. Its Piceance Basin habitat is open, barren, and made up of white shale outcrops in the Green River Formation. The topography has been shaped by rivers cutting down through the substrate. Much of the rock is oil shale covering deposits of natural gas. Heavy petroleum exploration and extraction activities occur throughout the area, and the region is mined for minerals such as nahcolite and dawsonite. This mining and surveying activity is the main threat to the species and its relative, the Dudley Bluffs bladderpod (Physaria congesta). This threat is considered "imminent". 100% of the plant's habitat is potential territory for oil and mineral mining. The threat includes drilling activity as well as associated activities including road maintenance, pipeline installation, utilities, and construction of new housing and power plants. Increased pollution and dust may affect the plants.The Dudley Bluffs twinpod is a perennial herb with a branching caudex covered with the shredded remains of previous seasons' leaves. The erect stems grow 12 to 18 centimeters tall. The wide lance-shaped basal leaves are 4 to 8 centimeters long. The upper leaves are narrower but not much shorter. The inflorescence is a loose raceme of flowers with yellow-green sepals and yellow petals up to a centimeter in length. The heart-shaped fruit is a hanging, inflated silique that is papery in texture and roughly half a centimeter long. The plant is pollinated by bees of the genera Halictus, Lasioglossum, Dialictus, and Andrena.Though rare overall with a very small distribution, this plant is locally abundant, with 10,000 individuals at one site. There are ten occurrences and an estimated total of up to 27,800 individuals.

Physalaemus pustulatus

Physalis heterophylla, colloquial name clammy groundcherry, is a herbaceous plant that is a member of the Solanaceae family. It is native to North America, occurring primarily in the eastern United States and Canada. It is known to occur in all contiguous states except for Nevada and California. It is found mainly in habitats such as dry or mesic prairies, gravel hills and rises, sandy or rocky soils, and waste places such as roadsides.Physalis heterophylla is a perennial, and is one of the taller-growing North American members of the genus, reaching a height up to 50 cm. The leaves are alternate, with petioles up to 1.5 cm, ovate in shape, usually cordate at the base (this is especially true of mature leaves), 6–11 cm long at maturity. Each member of the Physalis genus has at least one characteristic that makes it easy to differentiate in the field. For P. heterophylla, the stems and leaves are glandularly pubescent, giving it the "clammy" feel from which its name is derived. The plant also has distinctive thick rhizomes that run horizontal to the stem. Some sources recognize four distinct subspecies based primarily on leaf variation:P. heterophylla var. heterophylla, with thin leaves that have dentate margins;P. heterophylla var. clavipes, with thick, conspicuously veined leaves and sparingly tooth-like protrusions on otherwise entire margins;P. heterophylla var. ambigua, with thick, conspicuously veined leaves and dentate margins;P. heterophylla var. nycangienea, with thin leaves that have sparingly tooth-like protrusions on otherwise entire margins.The flowers are on simple inflorescences that emerge from leaf apexes. The petals are yellow on the exterior, and yellow on the interior with purple highlights emanating up each petal from the base. They are funnelform in shape, with five fused petals. There are five reticulated sepals, which enlarge after flowering to eventually protect the maturing fruit. Stamens five, with yellow anthers and purple filaments. The flowers face downwards when open, and are about 2.5 cm in diameter. The fruits are typical for the family (appearing like a tomatillo), and have a slightly bitter taste, though they are perfectly edible. The rest of the plant is poisonous.

It is endemic to western Colorado in the United States, where it is known only from seven occurrences in Rio Blanco County. It is federally listed as a threatened species.This is a petite perennial herb taking the form of a small, compact mound no more than about 2 centimeters tall. A short stem arises from a hairy caudex that remains buried in the soil. This is attached to a long, slender taproot. The leaves are linear or lance-shaped and measure up to 1.5 centimeters in length. They are coated in hairs, giving them a gray or silver color. The inflorescence is a raceme of flowers. It is so short it generally lies within the densely packed leaves. The flowers have bright yellow petals each about half a centimeter long. The fruit is a silique about the same length. The flowers are pollinated by the bee Andrena hicksii and other Andrena species.This plant grows on barren outcrops of rock in the notoriously petroleum-rich Piceance Basin. The substrate is pale to white in color, and the tiny, gray-colored plant is nearly invisible until it blooms in yellow flowers. The flat, open ground in the area is a section of the Green River Formation exposed when rivers and creeks cut through the rock. The rock covers a vast network of oil shale. About 90% of the plant's habitat is on land overseen by the Bureau of Land Management. The BLM is establishing a plan to balance the needs of the plant and other organisms in the habitat with the proposed oil and gas exploration in the immediate area. The rock is also mined for deposits of nahcolite and dawsonite, two types of sodium minerals.There are about 10,000 individual plants estimated to exist, all in an area of 88 square kilometers in one Colorado county. The plant is directly threatened by petroleum exploration activities. The effects of exploration on the species are not yet clear. While it is threatened, the species in general currently has a high probability of survival and does not yet meet the criteria for uplisting to endangered species status.

Physaria filiformis (syn. Lesquerella filiformis) is a rare species of flowering plant in the mustard family known by the common names Missouri bladderpod and limestone glade bladderpod. It is native to Missouri and Arkansas in the United States. It was federally listed as an endangered species in 1987 and it was downlisted to threatened status in 2003.Physaria filiformis is an annual herb producing several slender, branching stems up to 25 centimeters (10 inches) tall, growing erect or drooping. The leaves vary in shape, and the basal ones reach 2.4 centimeters (0.96 inch) in length. The inflorescence is a raceme of pale yellow flowers with petals half a centimeter to nearly one centimeter (0.4 inch) long. The fruit is a spherical silique. The plant is a winter annual, sprouting and forming a basal rosette of leaves in the fall and then producing stems and flower the following spring. Seeds are dispersed on the wind and in surface runoff.Physaria filiformis grows in limestone glades and outcrops of bare bedrock in southwestern Missouri and northwestern Arkansas. The surrounding habitat may be prairie and pasture. Several types of forest may be adjacent to the glades. The soil is shallow on the glades and supports few other plants. The plant grows less often in more vegetated areas with deeper soils, probably because other plants successfully compete with it there. It is also less abundant in the shady understory of Juniperus virginiana forest, as sunlight is a limiting factor in its growth. It can be found in a number of microhabitats, a factor that is important in its management and conservation. Wildfire is important in the maintenance of the limestone glade habitat and even more so its surrounding ecotones. Fire is the mechanism that keeps these habitats open and free of large and woody vegetation that shade out small annuals. Fire prevents ecological succession in the open habitat where the plant grows. Other plants in the local habitat include Arenaria patula, Camassia scilloides, Nothoscordum bivalve, Opuntia humifusa, Satureja arkansana, Tradescantia tharpii, and Verbena canadensis.As the health of the local ecosystem depends on fire, the practice of fire suppression has caused the degradation of the habitat. When fire is prevented, woody vegetation moves in, covering the glades and blocking the light from reaching this small plant. This encroachment of surrounding vegetation is a main threat to the species. Other threats include off-road vehicles, limestone mining, and urban development. Invasive species of plants have been introduced to the habitat, including Bromus tectorum, a competitive grass. The plant may be affected by grazing, trampling, and other disturbance, but these threats are mild because the plant can tolerate light disturbance.When Physaria filiformis was designated an endangered species there were nine populations. Extensive surveys located more occurrences and many of these were put under the protection of a number of agencies, including the National Park Service and The Nature Conservancy. By 2003 there were about 60 populations and the outlook for the plant had improved enough to warrant its downlisting to threatened status.Most occurrences of the plant are in southwestern Missouri. A large population can be found at Wilson's Creek National Battlefield. Conservation activities include protection of the habitat in public areas, prescribed burns to replace the natural fire regime, and reduced use of herbicides.

Physalaemus gracilis is a species of frog in the Leptodactylidae family. It is found in southern Brazil, Uruguay, and adjacent Argentina, and likely also in Paraguay.

Physaria pruinosa (syn. Lesquerella pruinosa) is a species of flowering plant in the mustard family known by the common names Pagosa Springs bladderpod and frosty bladderpod. It is native to Colorado and New Mexico in the United States.This plant is a perennial herb growing from a caudex which is clothed in the dried leaf blades of previous seasons. It is coated in short hairs, giving it a frosted look and giving it one of its common names. The decumbent or erect stems grow up to 20 centimeters long. The variously shaped leaves are up to 8 centimeters long. The inflorescence is a dense raceme of flowers with yellow petals roughly a centimeter long. The fruit is an inflated pod just under a centimeter long which is glossy and copper-colored. Flowering occurs in May through August.This plant occurs in the foothills of the San Juan Mountains. Its distribution runs through Archuleta and Hinsdale Counties in Colorado and Rio Arriba County, New Mexico, with its center near Pagosa Springs, Colorado. The land is managed by the United States Forest Service and the Bureau of Land Management, and part of the distribution lies on private land and the Southern Ute Indian Reservation.The habitat is made up of barrens and grasslands with the gray clay soils derived from the Mancos Shale. There are some occurrences near Ponderosa pines and Gambel oaks. It is also associated with Douglas-fir and Engelmann spruce. The plants grow in open areas, but can tolerate some shade. They are adapted to disturbed sites, as they grow on shales which are constantly crumbling and eroding. It can also grow on artificially disturbed sites such as roadsides and it can colonize bare soils. Associated plants include Arizona fescue, rushy milkvetch, mountain snowberry, sun sedge, Woods' rose, and Gray's Townsend daisy. It can be found growing with the rare species Pagosa skyrocket and Rothrock's Townsend daisy.The greatest threats to the survival of this plant are forces that destroy its habitat. These include development, off-road vehicle use, energy exploration and development, introduced species, herbicides, and grazing. Development in the vicinity of Pagosa Springs, Colorado, is probably the worst threat. Its habitat is currently being consumed for residential and commercial development. Roads are being constructed, destroying habitat and facilitating the spread of weeds that compete with the plant. Archuleta County, Colorado, "is one of the fastest growing counties in the United States."Estimates of the total number of plants remaining are anywhere between 5,209 and 20,619, with one estimate being 12,852 individuals.

Physaria fremontii (syn. Lesquerella fremontii) is a species of flowering plant in the mustard family known by the common name Fremont's bladderpod. It is endemic to Wyoming in the United States, where it occurs only in and around the Wind River Range in Fremont County.This species is a perennial herb growing from a taproot and producing decumbent or prostrate stems up to 15 centimeters long. The basal leaves are up to four or five centimeters long with oval blades borne on petioles. Longer, narrower leaves occur along the stems. The flowers have four yellow petals and measure 6 to 8 millimeters in length. The fruit is an inflated or flattened pod up to 7 millimeters long. It has a coating of hairs on the outer and inner surfaces.This plant is a calciphile, growing only on limestone or rocks that are partly limestone or are derived from limestone. It can be found up to 11,100 feet in elevation, up to the subalpine climates of the local mountains. It may be grow in Festuca idahoensis plant communities, and it is often associated with Pinus flexilis and Artemisia tripartita. The habitat is open. The landscape may have few plants, or it may be covered in cushion plants or dry mountain meadow species. Associated plants include Arenaria congesta (ballhead sandwort), Balsamorhiza incana (hoary balsamroot), Draba oligosperma (few-seed draba), Elymus spicatus (bluebunch wheatgrass), Erigeron compositus (cut-leaved daisy), Haplopappus acaulis (stemless mock goldenweed), Hymenoxys acaulis (stemless hymenoxys), Hymenoxys richardsonii (Richardson’s hymenoxys), Koeleria macrantha (Junegrass), Lomatium cous (biscuitroot), Lupinus argenteus (silvery lupine), Oxytropis sericea (white locoweed), Phlox hoodii (Hood’s phlox), Phlox multiflora (many-flowered phlox), Poa secunda (Sandberg bluegrass), Potentilla ovina (sheep cinquefoil), Sedum lanceolatum (lance-leaved stonecrop), Senecio canus (woolly groundsel), and Townsendia spathulata (spoon-leaved Easter-daisy).This plant's habitat is affected by road construction, limestone quarrying, and recreational activity such as off-road vehicle use.

Physalaemus petersi

Physaria thamnophila (syn. Lesquerella thamnophila) is a rare species of flowering plant in the mustard family known by the common name Zapata bladderpod. It is native to Texas in the United States, where it is known from Zapata and Starr Counties. The plant is threatened by the loss and degradation of its habitat. It is federally listed as an endangered species.This is a perennial herb producing one or more spreading stems from a woody base. The stems grow to 80 centimeters in maximum length. The herbage is silvery in color due to a coat of branching hairs. The leaves are oval to lance-shaped and smooth to faintly toothed on the edges, the lowest leaves reaching 12 centimeters long. The inflorescence is a raceme of yellow flowers. Blooming can occur through September whenever there is enough moisture. The population size can also increase rapidly after a significant amount of rainfall.This plant grows in desert shrublands above the Rio Grande floodplain in southern Texas. The substrate is calcareous clay and sandstone in geologic formations that contain an abundance of fossils. The terrain is sparsely covered by thorny shrubs and cacti, with the plant community dominated by Leucophyllum frutescens and Acacia berlandieri. Other plants in the habitat include Acacia rigidula (blackbrush acacia), Prosopis spp. (mesquite), Celtis pallida (granjeno), Yucca treculeana (Spanish dagger), Zizyphus obtusifolia (lotebush), and Guaiacum angustifolium (guayacan). Some shrubs may serve as nurse plants to the bladderpod, which grows in their shade and may benefit from their protection from soil erosion and herbivory by animals.This plant was thought to be limited to Zapata and Starr Counties in Texas, but there has been a documented population south of the border in Tamaulipas and the plant may occur in Webb County, Texas. There are approximately eleven populations known, but only about seven of these still exist. During dry spells the populations can shrink to low numbers, but flourish again when rain occurs.The main threat to the species is habitat destruction and modification. Non-native grass species have been introduced to the region to make pastures for grazing. Some areas have then become overgrazed. The landscape has been cleared and developed and associated infrastructure has been installed, including highways and transmission lines. There is active petroleum exploration occurring in the area.

Physaria chambersii

Physalospora thyoidea

Physalaemus nattereri (common name: Cuyaba dwarf frog) is a frog native to central and southeastern Brazil and eastern Bolivia and Paraguay. It has two "false eyes" on its rear. The 3–4 cm frog lifts its rear end when threatened, startling predators. This trait is so dangerous and intimidating because, no matter if you're at the front or the back of the frog, it will always appear to be staring at you. If a predator does not get fooled by the eyespots, and decides to move closer, the frog can produce an unpleasant secretion that comes from glands located in the eyespots. It has short limbs, and a plump body.

Physalaemus barbouri
