About plant names...

Laxflower is native to northern Mexico and the south­western United States, at elevations of less than 3000' (914 m). It prefers sandy habitats and full sun.

Plants: 4-20" (10-50 cm), often branched. Stems are silvery (tomentose) due to the presence of many tiny hairs.

Leaves: Basal leaves wither quickly. Leaves higher up are 1½-6" (4-14 cm) long, linear-oblong to lanceolate or oblanceolate, sometimes deeply lobed.

Flowers: Composite flowers are yellow. Each stem contains 2-3 flowers. Each flower contains 4-8 obovate rays, each with 3 shallow lobes, yellow or pale yellow. There are 8-20 disc flowers, also yellow, and hairy. Flowers appear from March to May.

Fruits: Club-shaped, ⅛-³/₁₆" (4-5 mm), evenly ribbed.

Medical: Contains odoratin and paucin, which may prove effective against certain cancers.
