Atrichoseris is a genus of plants in the family Asteraceae.[2][1] It contains only one known species, Atrichoseris platyphylla, known by the common names tobacco weed, parachute plant, and gravel ghost.[3]
A. platyphylla is native to the deserts of the southwestern United States (southern California, Arizona, Nevada and the southwestern corner of Utah) and northwestern Mexico (Sonora, Baja California).[4][5][6]
The plant produces a low basal rosette of rounded leaves patterned with gray-green and purple patches at ground level. It sends up a weedy-looking thin branching stem up to 70 centimetres (28 inches) tall, topped with a number of attractive, fragrant white or pink-tinged flowers, about 2.5–5 cm (1–2 in) wide,[4] the layered ray florets rectangular and toothed.[5][6] The flowers bloom between February and May.[4] The hairless fruit has the shape of a five-sided club.[4]
The genus name, Atrichoseris, means 'chicory plant without hairs', referring to the fruit, and the specific epithet, platyphylla, means 'flat-leaved'.[4]
