Heliophila scoparia Burch. ex Dc.

Erect glabrous shrubs up to 1 m high, branched from the base. Stems densely leafy, brown, striate with decurrent lines or ridges. Leaves 0.5-5 cm long, 1-3.5 mm broad, broadly linear to linear-subulate or lanceolate, acute or mucronate, coriaceous, rigid, often appressed, smooth or wrinkled when dry, sometimes rough with rows of short triangular papillae, these sometimes joined in twos or threes, sulcate above, subtended by 2 minute stipules; leaf-scars prominent. Racemes terminal on abbreviated shoots along the main stems, 1-4-flowered, sometimes those on more robust branches several-to many-flowered, but then usually with fewer small lateral inflorescences. Pedicels subtended by 2 minute bracts, 0.4-1.6 cm long in flower, only slightly longer in fruit, erect, stout. Sepals 4.5-7 mm long, 1.5-2.5 mm broad, linear-oblong or narrowly obovate-oblong, obtuse; outer 2 ± keeled, thickened at the apex and slightly cucullate; inner 2 saccate with broad membranous margins. Petals 7-12 mm long, 2.5-7.8 mm broad, obovate or oblanceolate-spathulate, clawed. Filaments 3.5-6.5 mm and 4.5-7.3 mm long, smooth, subulate. Anthers 1-2 mm long. Ovary linear, sessile or shortly stipitate, style short, stigma small; ovules 10-36. Fruits 3-12 cm long, 2-4 mm broad, linear, erect, sessile or shortly stipitate; valves flat with straight margins, midrib prominent, sometimes slightly muricate-papillate; style 1.5-4 mm long, but often appearing longer because the valves taper towards the apex. Seeds 2.8 x 3.5-4 mm, oblong-circular, brown, winged, papillate.
