Heliophila hurkana Al-shehbaz & Mumm.

Erect, virgate, woody shrubs up to 2 m high, many-stemmed; terminal branchlets slender, straight, mostly inbranched. Leaves 0.4-1 cm long, linear, acute, channelled above, slightly glaucous, few, sparse. Racemes terminal, lax, at flowering time those of the previous season still persisting with the remains of the fruits. Sepals 2.5-3 mm long, oblong, finely 3-nerved. Petals 10-15.5 mm long, 2.8-5 mm broad, oblanceolate to oblanceolate-spathulate, rounded, long-clawed. Filaments 1.5-1.9 mm and 1.9-2.3 mm long. Anthers 1-1.5 mm long, minutely apiculate. Ovary narrowly elliptic, sessile, with a short, thick style. Fruiting pedicels 5-6.5 mm long, erect, slender, thickened at the apex. Fruits 1-1.4 cm long (including the style), 3.5-4.8 mm broad, elliptic, flattened, narrowed at both ends, beaked, the beak and style together 2.5-4 mm long (the style 1.5-2 mm); seen from the outside the valves have raised margins and are slightly bulged in the middle, 1-nerved, finely reticulately ridged especially near the margins; seen from the inside each valve has a thickened central plate corresponding in size and shape to the septum; at either end of this plate the midrib emerges from and lies on the inner surface of the valve; when the fruit dehisces each valve remains hanging from the free midrib which lies in a groove along the beak of the replum and which enters again into the style; eventually the midrib breaks and the valves falls away. Seeds 3-3.4 x 2.3-2.5 mm, oval, subcompressed, narrowly winged.
