Taraxacum pamiricum Schischk.

Taraxacum atrans is a species of terrestrial,[1] perennial,[2] herb[3] in the family Asteraceae native to the region from central Asia to Mongolia and West Himalaya.[2]

Description

Vegetative characteristics

Taraxacum atrans is a terrestrial,[1] perennial,[2] 6–10 cm tall[4] herb[3] with slender roots.[5] The rosulate,[6] glabrous, oblanceolate,[7] undivided leaves[5] with glabrous, pale green, winged or unwinged petioles[7] are 2–8 cm long, and 3–12 mm wide.[5]

Generative characteristics

The solitary to few[5] brown to green scapes[7] with arachnoid hairs below the capitulum are almost as long as the leaves.[5][7] The yellow capitulum is 1.5–2 cm wide.[7] The florets are light yellow.[5] Pollen is rarely produced, but if present, the grains are irregularly sized.[7] The achenes are yellowish-brown.[5] The yellowish white pappus is 5.5–6 mm long.[4]

Taxonomy

It was described by Boris Konstantinovich Schischkin in 1964.[5][2] It has one synonym: Taraxacum pamiricum Schischk.[1][2][8] However, it was remarked that it is difficult to compare Taraxacum atrans to other taxa, because the type specimen does not posses achenes and the description of the achenes in the original publication may refer to unripe achenes or to achenes from another species.[7]

Etymology

The specific epithet atrans means darkening.[9]

Distribution and habitat

It is native to Kazakhstan, Kirgizstan, Mongolia, Tadzhikistan,[2] Pakistan, and India,[8] where it occurs in alpine pastures,[10] stony slopes, gravel beds,[5] and alpine salt-marshes.[11]

Cultivation

It can be cultivated in moist[12] or well drained,[6] gravelly,[6][12] humus-rich soil under bright conditions.[12]
