Heliophila bulbostyla P.E.Barnes

Erect annual herbs up to 35 cm high; slender and simple or stout with spreading branches; rarely quite glabrous, usually the hypocotyl or lower few nodes and axils of branches minutely puberulous. Leaves 2-7.5 cm long, the lower ones 3-7-lobed, the uppermost simple, broadly linear to filiform, glabrous or the upper surface sparsely puberulous; each subtended by 2 minute stipules. Racemes terminal, rather lax; buds rounded. Pedicels generally puberulous in the lower half, each subtended by 2 minute bracts; in fruit 0.4-1.3 cm long, ascending, stout and thickened, especially apically, or slender (in shade forms). Sepals 3.5-5.9 mm long, oblong, semi-persistent; the outer 2 cucullate, membranous-margined; the inner 2 inflated at the base, with broad membranous margins. Petals 6-8.5 mm long, 3-6.5 mm broad, obovate to obovate-circular, rounded, clawed, each with a papillate appendage. Filaments 2.8-4.5 mm and 3.1-4.9 mm long, the 2 short ones each with an appendage. Anthers 1-2 mm long. Ovary linear, style short, soon becoming thickened; ovules 20-44. Fruits 3.5-5.5 cm long, 1.2-1.4 mm broad, linear, margins thick, almost straight or moniliform; valves 1-nerved, flat, in older fruits generally calloused between the seeds, glabrous or puberulous when young; style 3 mm long, spherical to clavate-globose. Seeds 1.2-1.4 x 0.8-0.9 mm, oblong, immarginate or very narrowly margined.
