Morphological description

Perennial or more rarely annual, usually with woody base and numerous herbaceous to more or less woody erect to prostrate stems up to 70 cm long, often stunted by browsing, stems often longitudinally ribbed, ribs often scabrid-tuberculate, older parts covered by yellowish-brown to almost black bark. Leaves linear or narrowly oblong to spathulate, (2-)4-14(-35) x (0.3-)0.6-1.5(-3) mm, alternate but often fasciculate, especially on young shoots, often somewhat fleshy, smooth to scabrid-tuberculate on margins. Stipules subulate, 0.2-0.5 mm long. Inflorescence a spike or spike-like raceme, (3-)5-10(-20) cm long. Bracts about as long as the sepals, narrowly triangular to ovate-triangular with broad white margins, (1.1-)1.2-2(-2.5) x (0.5-)0.6-1(-1.1) mm, usually with a stipuloid appendage about 0.2 mm long on each side near the base. Sepals 5, rarely 3 or 4, narrowly to fairly broadly oblong-ovate with broad white margins, (1-)1.2-2(-2.3) x (0.4-)0.5-0.8(-1) mm. Petals 2, rarely 3 or 4, white, sometimes tinged with pink, longer than the sepals, narrowly to fairly broadly oblong-ovate, oblong-obovate or spathulate-oblong, sometimes obliquely so, (1.2-)1.8-2.5(-2.8) x (0.6-)0.8-1.3(-1.5) mm, entire or margins irregularly undulate, crenate or shallowly lobed. Stamens usually 8-12, equally distributed around ovary, sometimes partly abortive with only 3-5 functional adaxial stamens or completely abortive; filaments 1-2.2(-3.2) mm long, anthers 0.4-0.7 mm long. Capsule subspherical to oblong-ovoid, 3-6 mm long and 2-3.5 mm broad. Seeds about 0.6 mm long, reniform to subspherical. From: Leistner, OA. 1970. Resedaceae. Fl. S. Africa 13: 177-184. Dept. Agric. and Technical Services, Pretoria. [CC BY]

Erect suffrutex, woody at base, 0.2-0.7 m high; glabrous. Leaves crowded at nodes, linear to obovate. Inflorescences elongating racemes, up to 250 mm long; peduncles finely ribbed. Flowers white, rarely pinkish; pedicels wanting; bracts shorter than flowers. Petals 2, narrow, exceeding sepals, tardily deciduous. Ovary subglobose to obovoid, ± 3.5 mm long; shallowly sulcate, carpels 4 or 5, not completely fused at top, with 4 or 5 apical, conical teeth bearing stigmatic surfaces; ovules 6 per placenta, in 2(3) rows.
