Species

Angiosperms > Brassicales > Brassicaceae > Heliophila

Characteristics

Slender or stout, erect, annual herbs 15-50 cm high, simple or branched, completely glabrous or minutely puberulous for the first few nodes, on the axils of the lower branches, the upper surface of the leaves, and the lower part of the pedicels. Leaves 5-7 cm long, filiform or linear, simple or 3-lobed near the tip, mostly crowded in the lower half of the stem; upper leaves few, smaller, always simple. Racemes dense in flower and in fruit, in small unbranched plants sometimes lax; buds narrow, pointed. Pedicels in fruit 0.3-1 cm long, thickened near the appe x but never very stout and uniformly thick; erect, ± appressed. Sepals 4-5 mm long, linear-oblong, purplish, semi-persistent; the outer 2 cucullate, thickened at the apex or slightly horntipped; the inner 2 ± saccate. Petals 6-7 mm long, 2.5-3 mm broad, oblong-obovate or elliptic-obovate, rounded, cuneate but not distinctly clawed, each with a small appendage (sometimes very small and some distance from the base). Filaments 3-3.8 mm and 3.5-4.5 mm long. Anthers 1-1.4 mm long. Ovary linear; style soon beginning to thicken; ovules 24-38. Fruits 3-5.5 cm long, 0.9-1.4 mm broad, linear, regularly but very shallow-1y moniliform; valves 1-nerved, smooth, the margin thickened; style 1-2.8 mm long, globose or thick, cylindrical.
