扁毛菊属 bian mao ju shu

Authors: Zhu Shi, Christopher J. Humphries & Michael G. Gilbert

Waldheimia Karelin & Kirilov.

Herbs, perennial, glabrous to densely tomentose. Leaves alternate, closely spaced, sometimes rosulate, spatulate or cuneate, apex 3-5-lobed or -parted, or oblong, pinnatisect or pinnatipartite. Capitula solitary, pedunculate, heterogamous, radiate. Involucre hemispheric; phyllaries in 3 or 4 rows, scarious margins dark brown. Receptacle convex, epaleate. Marginal florets in 1 row, female or neuter, usually sterile; lamina pink, white, or bluish violet. Disk florets many, yellow or bluish violet, bisexual, fertile; corolla tubular, apex 5-lobed. Anther bases obtuse, apical appendage ovate-lanceolate. Style branches linear, apex truncate. Achenes somewhat curved, faintly 5-10-ribbed, generally with sessile glands, sometimes pilose. Corona of 20-50 bristlelike scales, with flat and palmate base, apex brownish, sometimes wider.

Eight species: Afghanistan, China, India, Kazakhstan, Mongolia, Nepal, Pakistan, Russia, Tajikistan, Uzbekistan; eight species (one endemic) in China.

The exact date of publication of Allardia is uncertain, but such evidence as there is (Zain-ul-Abidin, Biologia 4: 212-214. 1958) suggests that it was in 1841, thus predating Waldheimia, which was published in 1842.
