Annual, erect, little branched, or diffuse with numerous ascending 
branches, more or less glandular-hirtellous, about 1-24 ft. high; stem 
and lower branches terete, faintly striate, upper branches alate. Leaves 
narrowly lanceolate or linear, acute or subacute, mucronate, denticulate, 
sessile, decurrent, membranous, 1-3 in. long by 4,—2 in. wide. Capi- 
tula 3-9 (usually 4-) flowered, of which 1 fl. (central) only is male, 
crowded many together in subhemispherical subsessile or shortly pe- 
dunculate heads 4-4 in. diam., terminating the stem and branches. 
Scales of partial involucre 3—5, scarious, linear-oblon g, obtuse, apiculate, 
ciliate at apex, otherwise glabrous. Outer axial scales nearly equalling 
the head, closely appressed, broadly ovate, apiculate, pubescent. Com- 
mon receptacle slightly convex. Corolla with scattered sessile glands.

Capitula heterogamons, discoid, few-flowered, collected in globose 
G8; outermost florets pistillate, 2 (or few), inner 3 usually 4 (in 
frican sp.), fertile or sterile, each floret subtended by a scale equalling 
or exceeding it in length, the capitulum subtended by an axial scale. 
Corolla of 9 fi, narrowly tubular, of 3 floret slightly wider upwards, 
5-toothed, Anther-base taiJed, tails cohering in pairs. Style papillose, 
apex minutely bifid. Achene of 2 fil. broadly alate with coriaceous 
ings, concave, somewhat keeled, apex bifid; pappus of 3-4 stout bar- 
bellate sete.—Shrubs or undershrubs. Leaves alternate, ovate or 
ceolate. Heads of capitula terminal, globose, 4-14 in. diam.
