| Description: | Annual or biennial herb with much-branched, prostrate or ascending, pubescent stems up to 50 cm long, strong-smelling when crushed. Lower leaves pinnately lobed with the lobes pinnatifid; cauline leaves sessile with the lobes entire, all leaves sparsely pubescent to subhairless. Flowers very small, whitish, in dense leaf-opposed racemes, elongating up to c. 6 cm. Petals 0 or c. 0.5 mm, shorter than the sepals. Stamens 2(-5). Fruit c. 2.5 mm wide, constricted in the middle into 2 subspherical, 1 seeded mericarps. Seeds ellipsoid, flattened, orange-brown. (from Flora of Zimababwe website) Procumbent or erect herbs up to 30 cm high. Stems pilose, glabrescent. Basal leaves up to 9 cm long, pinnatipartite, the segments usually pinnatifid, sometimes only the upper margin of the segments lobed. Upper leaves pinnatifid, smaller. Racemes short and dense in flower, 2-3 cm long in fruit; rhachis pilose. Sepals 0-8-0-9 mm long, greenish white. Petals less than 0-5 mm long, white. Stamens 2 or rarely 4; filaments swollen at the base. Siliculae on spreading or recurved-spreading pedicels 1.5-2.5 mm long, 1-4-1-5 mm long, 2-2-6 mm broad, each half reniform-semi-circular, longer than wide, compressed, rounded on the back, reticulately netted and pitted; style always much shorter than the sinus. (from JSTOR Global Plants website / Flora of Southern Africa) Annual or biennial, foetid herb with slender tap-root and prostrate or ascending, much branched, shortly pilose stems up to 40–50 cm tall. Lower leaves petiolate, pinnatisect, lobes pinnatifid; cauline leaves sessile, with narrow almost entire segments, all sparsely pubescent or nearly glabrous. Flowers small, whitish, pedicellate, pedicels 1–2 mm long, in rather dense racemes elongating to about 6 cm, appearing extra-axillary or leaf-opposed but really terminal. Sepals c. 0.5 mm long. Petals 4, shorter than the sepals. Stamens 2 (rarely 4 or 5). Fruit 1.5–1.8 x 2.5 mm constricted at the septum into 2 subspherical, reticulate-pitted 1-seeded mericarps. Seeds 1 x 0.5 mm, orange-brown, flattened-ellipsoid. (from JSTOR Global Plants website / Flora Zambesiaca) |
