Physaria arctica is a perennial flowering herb in the family Brassicaceae, known by the common name arctic bladderpod. [1]
Plants are 6–12 cm high [2] with a short taproot and woody stem-base. Basal leaves, 2–6 cm and arranged in a rosette [3] predominate, and are obovate to oblanceolate, while cauline leaves, sessile or shortly petiolate, are oblanceolate or lingulate and 0.5-1.5 cm. [4] Inflorescences are loosely racemose, with flower stalks ascending or erect and 5–20 mm. There are 3-8 radially symmetrical flowers per inflorescence, [3] and the petals are spaulate, 5-6mm, with blades that narrow gradually to the claw. [4]
Physaria arctica grows in sand and gravel from calcareous bedrock, river bars and terraces, cliff ledges, scree and talus slopes. [4]
Petasites frigidus, the Arctic sweet coltsfoot or Arctic butterbur, is a species of flowering plant in the family Asteraceae. It is native to Arctic to cool temperate regions of the Northern Hemisphere in northern Europe, northern Asia and northern North America.
Salix arctica, the Arctic willow, is a tiny creeping willow. It is adapted to survive in Arctic conditions, specifically tundras.
Festuca altaica, also known as the altai fescue, or the northern rough fescue, is a perennial bunchgrass with a wide native distribution in the Arctic, from central Asia to eastern North America. It was first described in 1829 by Carl Bernhard von Trinius. It is under the synonym F. scabrella, the rough fescue.
Stylidium fimbriatum is a dicotyledonous plant that belongs to the genus Stylidium. It is an erect annual plant that grows from 15 to 30 cm tall. Oblanceolate leaves, about 16 per plant, form a basal rosette around the compressed stems. The leaves are generally 5–20 mm long and 2–7 mm wide. This species generally has one or two scapes and cymose inflorescences that are 15–30 cm long. Flowers are pink with yellow highlights. S. fimbriatum's distribution is confined to the area around Bachsten Creek in the Kimberley region in Western Australia. Its typical habitat is herbfields that are seasonally wet.
Chorizanthe orcuttiana is a rare small annual plant in the buckwheat family, Polygonaceae. It is known commonly as Orcutt's spineflower or the San Diego spineflower, and it is endemic to San Diego County, California. The plant is diminutive, and a hand-lens is necessary for proper identification. The plant is very sensitive to temperature and precipitation, and under drought or hot conditions the seeds will not germinate or survive. The plant is visible anywhere from February through July during good rain year, but most years the plant is only visible from April to June. Each minute flower yields one seed.
Turritis glabra, commonly known as tower rockcress or tower mustard, is a tall, slim, grey-green plant with small creamy flowers at the top of the stem. It usually grows on poor chalky or sandy soils, in open situations. It is native to Europe, Asia, and North Africa, and it is widespread in North America where it is also probably native. It can be found in many other parts of the world as an introduced species.
Dudleya blochmaniae is a summer-deciduous succulent plant known by the common names Blochman's liveforever or Blochman's dudleya. This species of Dudleya survives part of the year with no aboveground presence, surviving as underground corm-like roots in deciduous months. It is characterized by white, star-shaped and spreading flowers that emerge after sufficient rainfall. It is found along the Pacific coast of the California Floristic Province, from the vicinity of San Luis Obispo in California to Punta Colonet in Baja California.
Symphyotrichum pilosum is a perennial, herbaceous, flowering plant in the Asteraceae family native to central and eastern North America. It is commonly called hairy white oldfield aster, frost aster, white heath aster, heath aster, hairy aster, common old field aster, old field aster, awl aster, nailrod, and steelweed. There are two varieties: Symphyotrichumpilosum var.pilosum, known by the common names previously listed, and Symphyotrichumpilosum var.pringlei, known as Pringle's aster. Both varieties are conservationally secure globally and in most provinces and states where they are native.
Physaria bellii is a species of flowering plant in the family Brassicaceae known by the common names Bell's twinpod and Front Range twinpod. It is endemic to Colorado in the United States.
Luzula nivalis, commonly known as arctic wood-rush or less commonly as snowy wood-rush, is a species of perennial rush native to the North American Arctic and Northern Europe. It was described by Polunin (1940) as one of the most abundant, ubiquitous, and ecologically important of all arctic plants.
Physaria congesta is a rare species of flowering plant in the mustard family known by the common name Dudley Bluffs bladderpod. 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.
Iris sanguinea is a rhizomatous flowering plant in the genus Iris and in the series Sibiricae. It is cultivated as an ornamental plant in temperate regions. It is one of the species considered a Japanese iris. It is from Asia, found between Russia, Mongolia, China, Japan and Korea. It has grey green leaves, an unbranched flowering stem and flowers in reddish-purple shades, from blue to blue-purple, red-violet, with a rare white variant.
Platanthera dilatata, known as tall white bog orchid, bog candle, or boreal bog orchid is a species of orchid, a flowering plant in the family Orchidaceae, native to North America. It was first formally described in 1813 by Frederick Traugott Pursh as Orchis dilatata.
Symphyotrichum racemosum is a species of flowering plant native to parts of the United States and introduced in Canada. It is known as smooth white oldfield aster and small white aster. It is a perennial, herbaceous plant in the family Asteraceae. It is a late-summer and fall blooming flower.
Draba norvegica is a species of flowering plant in the mustard family (Brassicaceae) know by the common names Norwegian draba and Norwegian whitlow grass.
Symphyotrichum molle is a species of flowering plant in the aster family (Asteraceae) endemic to the Bighorn Mountains of Montana and Wyoming in the United States. Commonly known as soft aster, it is a perennial, herbaceous plant that ranges from 30 to 60 centimeters in height.
Dudleya cymosa subsp. paniculata, known by the common name Diablo Range dudleya, is a species of perennial succulent plant in the family Crassulaceae native to the Inner South Coast Range of California. It is characterized by pale yellowish flowers, oblong to oblanceolate leaves and a growth habit not limited to a single substrate. It is closely related to Dudleya abramsii subsp. setchellii.
Dudleya cymosasubsp. pumila, most commonly known as the low canyon dudleya, chalky canyon dudleya or California live-forever, is a species of perennial succulent plant. It has diamond to spoon shaped leaves, sometimes coated with a fine white powder, and in May through July, bright red, orange or yellow flowers adorn the short inflorescence. A leaf succulent primarily found growing in rocky cliffs and slopes, it is endemic to California, and grows in the Transverse Ranges and South Coast Ranges, with some outlying populations. A variable plant, in some localities it is difficult to distinguish from other plants in the genus.
Symphyotrichum kentuckiense is a rare species of flowering plant in the Asteraceae family and is commonly known as Kentucky aster, Price's aster, Miss Price's aster, Sadie's aster, or lavender oldfield aster.
