Family Compositae

The largest family of flowering plants , the Compositae (Asteraceae), comprising about 1,100 genera and more than 20,000 species and characterized by many small flowers arranged in a head looking like a single flower and subtended by an involucre of bracts. A head may consist of both ray flowers and disk flowers, as in the sunflower, of disk flowers only, as in the burdock, or of ray flowers only, as in the dandelion.

Genus Brickellia

Annuals , perennials , subshrubs , or shrubs , (12-) 30-120(-200) cm. Stems mostly erect , often much branched (sometimes virgate , often striate ). Leaves cauline; opposite or alternate; petiolate or sessile; blades usually 3-nerved from bases , deltate, lance-elliptic, lance-linear , lanceolate, lance-ovate, lance-rhombic, linear , oblong , obovate , ovate , rhombic-ovate, spatulate , or suborbiculate, margins mostly crenate , dentate , entire, laciniate-dentate, lobed , serrate, or toothed , faces glabrous (sometimes shiny) or glandular-puberulent, strigose , or tomentose , sometimes gland-dotted. Heads usually in corymbiform , sometimes cymiform, paniculiform , or racemiform , arrays, rarely borne singly. Involucres cylindric to obconic or campanulate , 5-12 mm diam. Phyllaries persistent , (10-) 14-45(-60) in 3-7(-9) series, usually (4-) 5-6(-16) -striate or -nerved, linear or lanceolate to oblanceolate or oblong, usually unequal (usually chartaceous , sometimes herbaceous). Receptacles flat to convex , epaleate. Florets (3-) 8-45(-90) ; corollas usually white or whitish to cream, sometimes greenish, purplish or yellowish, throats mostly cylindric to narrowly funnelform (lengths 3-5 times diams.) ; styles: bases enlarged, hairy , branches narrowly clavatedilated distally). Cypselae narrowly prismatic , 10-ribbed, glabrous or hairy to glabrate , often gland-dotted; pappi persistent, of 10-80 usually smooth or barbellulate to barbellate , sometimes plumose or subplumose bristles in 1 series. x = 9.

Species ca. 100: North America, Mexico, Central America.[1]
