Description

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 Saussurea

Perennials , 5-120+ cm; herbage tomentose or glabrescent , not spiny . Stems erect or ascending , simple or branched. Leaves basal or cauline (sometimes cauline only), sessile or petiolate ; blade margins entire or dentate to pinnately lobed , faces glabrous to densely tomentose, glandular or eglandular . Heads discoid , borne singly or in corymbiform arrays. Involucres ovoid to campanulate or ± turbinate . Phyllaries many in 3-5(-10+) series, subequal to strongly unequal, appressed or not, ovate to lanceolate, margins entire, toothed , or lobed, apices obtuse or acute, appendaged or not, not spine-tipped. Receptacles flat or convex , epaleate, smooth , usually subulate-scaly, sometimes bristly or naked. Florets 10-20; corollas white to blue or purple, tubes slender, abruptly expanded to throats , lobes linear ; anther bases short-tailed, apical appendages linear, acute; style branches: fused portions with minutely hairy subterminal nodes, distinct portions oblong to linear, short-papillate. Cypselae oblong, ± angled , cylindric or 4-5-angled, ribs (when present) smooth or roughened, apices entire, glabrous or minutely glandular, attachment scars basal; pappi usually of 2 series, outer of readily falling, short bristles , inner persistent or falling as unit , of basally connate , usually longer , plumose bristles. x = 13, 14, 16, 17, 18, 19?.
