hole-in-the-sand plant
erect or spreading, branched from bases or throughout.
cauline; mostly alternate (1–4 proximal pairs opposite);
blades mostly 1-pinnately lobed (lobes usually 3–11, bristle-tipped), ultimate margins entire, faces glabrous (often glaucous, oil-glands subterminal).
campanulate to turbinate or fusiform, 4–8(–10) mm diam.
convex to conic, ± pitted, epaleate.
7–12, pistillate, fertile;
corollas whitish with pinkish to purplish stripes.
15–100+, bisexual, fertile;
corollas yellow or purplish or whitish, tubes much shorter than cylindric throats, lobes 5, deltate to lanceolate.
persistent, 6–12 in ± 2 series (distinct to bases, lanceolate or ovate to linear, most bearing 1–5 oil-glands).
of 2–6 deltate to lanceolate bractlets (each usually bearing 1–5 oval to linear oil-glands).
radiate, borne singly.
clavate, sparsely puberulent (hairs usually reddish);
