Calamagrostis purpurascens, is a perennial grass commonly known as purple reedgrass, purple pinegrass, or alpine reedgrass. [26]
Calamagrostis purpurascens is a large, clump forming, perennial grass; growing 30-80 cm (12-31 in.) tall. [27] It grows from short rhizomes and has dense, often purpled tinted flower heads that are 4 to 13 cm (1.6 to 5.1 in.) long. It has one flowered spikelets, two subequal glumes, and lemma with a dorsal awn. The awn is longer than the glum and sharply bent, and longer than the tip of the spikelet. Flowering stems have typically one or two leaves. [28]
Calamagrostis purpurascens is native from arctic Greenland, to much of Canada (Alberta, British Columbia, Manitoba, Newfoundland, Northwest Territories, Nunavut, Ontario, Quebec, Saskatchewan, and Yukon Territory) and the western and northern U.S. (Alaska, California, Colorado, Idaho, Minnesota, Montana, Nevada, New Mexico, Oregon, South Dakota, Utah, Washington, and Wyoming). [4] It is rare and scattered in the southern U.S. states, such as Louisiana, where it is a post-glacial relict.
Further south, C. purpurascens is also known in Chile, where it was recorded by Rodolfo Amando Philippi in 1860. Philippi gave it the name Deyeuxia robusta, now relegated to synonymy. [24]
Calamagrostis purpurascens grows in dry mountainous zones, from high up on the foothills to close to the snow-line, often taking root in gaps in the talus, where few other plants can grow. [27] It is an arctic-alpine species with disjunct boreal populations in eastern North America. [28] In Minnesota it is an endangered species found growing in the north eastern part of the state in the coniferous region in Cook county where it is found on tall north facing cliffs composed of slate and diabase; these locations are cool, moist, and lack heavy competition from other plant species. [28] [29]
Carterocephalus palaemon (arctic skipper) butterflies eat the nectar from C. purpurascens flowers, and their caterpillars feed on the shoots. [30] Ovis canadensis (bighorn sheep) are known to graze this grass. [26]
Stipa is a genus of around 300 large perennial hermaphroditic grasses collectively known as feather grass, needle grass, and spear grass. They are placed in the subfamily Pooideae and the tribe Stipeae, which also contains many species formerly assigned to Stipa, which have since been reclassified into new genera.
Anemone caroliniana, the Carolina anemone, is a species of herbaceous flowering plant in the family Ranunculaceae. Plants grow (7)10 to 40 cm tall, from short tuber-like rhizomes that are 10–30 mm long. Stem leaves without petioles. Plants flowering early to mid spring with the flowers composed of 10 to 20 sepals normally white or soft rose colored but also purple, one flower per stem, the sepals are 10 to 22 mm long and 2–5 mm wide. Fruits in heads ovoid to subcylindric in shape, 17–25 mm long.
Ceanothus griseus is a species of flowering shrub known by the common names Carmel ceanothus and Carmel creeper. 'Carmel' refers to the Carmel-by-the-Sea region in California.
Tussock grasses or bunch grasses are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season. Tussock grasses are often found as forage in pastures and ornamental grasses in gardens.
Calamagrostis canadensis is a species of grass, having three or more varieties, in the family Poaceae. It is known variously by the common names of bluejoint, bluejoint reedgrass, marsh reedgrass, Canadian reedgrass, meadow pinegrass, Canada bluejoint and marsh pinegrass.
Calamagrostis koelerioides, the fire reedgrass, dense-pine reedgrass, or the pineland reed grass, is a species of grass in the family Poaceae native to western North America. It ranges from western Wyoming to Washington state, south to Mexico. It is found in many habitat types, including mountain meadows, chaparral, pine and spruce forests, and on slopes, dry hills, and ridges.
Bromus maritimus is a species of brome grass known by the common names maritime brome and seaside brome. It is native to the coastal areas of California and Oregon.
Ribes velutinum is a species of currant known by the common name desert gooseberry.
Salix geyeriana is a species of willow known by the common names Geyer's willow, Geyer willow and silver willow. The type specimen was collected by the botanist Karl Andreas Geyer, for whom it was named. Its conspicuous, yellow flowers begin to bloom as early as March, to as late as the end of June.
Bolboschoenus robustus is a species of flowering plant in the sedge family. It is known by many common names: saltmarsh bulrush, alkali bulrush, sturdy bulrush, seacoast bulrush, stout bulrush, three-cornered sedge or leafy three-cornered sedge, and seaside club-rush.
Ceanothus americanus is a species of Ceanothus shrub native to North America. Common names include New Jersey tea, Jersey tea ceanothus, variations of red root, mountain sweet, and wild snowball. New Jersey tea was a name coined during the American Revolution, because its leaves were used as a substitute for imported tea.
Calamagrostis lapponica, the Lappland reedgrass, is a grass species native to colder parts of the Northern Hemisphere. It has been reported from Scandinavia, Russia, Greenland, Alaska, and every Canadian province and territory except the Maritime Provinces.
Calamagrostis tweedyi, the Cascade reedgrass or Tweedy's reedgrass, is a perennial in the grass family. It is native to the Pacific Northwest in the United States, in Washington, Oregon, Idaho, and Montana.
Sporobolus vaseyi, also known as Florida sandreed, is a species of perennial plant endemic to Florida.
