± erect or spreading, branched ± throughout.
cauline; all or mostly opposite;
petiolate or sessile;
blades mostly ternately lobed (blades or lobes lanceolate to lance-linear), ultimate margins entire, faces sparsely to densely scabrellous (hairs white, straight, conic or fusiform, 0.1–0.4 mm) and gland-dotted.
turbinate or obconic to ± hemispheric, 5–6+ mm diam.
± convex, ± pitted, epaleate.
3–8, pistillate, fertile;
corollas usually yellow, sometimes ochroleucous.
20–40+, bisexual, fertile;
corollas yellow to orange (gland-dotted), tubes about equaling funnelform to campanulate throats, lobes 5, deltate to lance-deltate.
persistent, 6–10 in 1–2 series (reflexed in fruit, distinct, oblanceolate, subequal, herbaceous, margins membranous, not purplish).
radiate, borne singly or (3–6) in loose, corymbiform arrays.
narrowly obpyramidal, 4-angled, finely nerved, shaggily hairy (at least at bases) and/or gland-dotted;
pappi persistent, of 8–10 (distinct) ovate or elliptic to lanceolate or linear-subulate (basally and/or medially thickened, distally and/or laterally scarious) scales in 1 series (weakly, if at all, aristate).

Picradeniopsis
Species 2 (2 in the flora).
According to T. F. Stuessy et al. (1973), among others, Picradeniopsis is closely allied to Bahia. Indeed, the species are often treated as members of Bahia. Where they occur together, the two species of Picradeniopsis may produce more or less sterile hybrids.
