Stem subangular, yellowish, erect, usually with several ascending branches, some often longer than the main stem. Leaves with petiole up to 2(-4) cm; blade elliptic, up to 6 cm. fairly shallowly pinnatifid, with 2-4 wide lobes and several teeth on each side, sometimes dull green; base cuneate to very broadly cuneate; apex +/- obtuse, upper ones sometimes apiculate. Bracts lanceolate, small. Inflorescences terminal and axillary, elongated, bracteate almost to the top, on the main stem up to 3 cm wide, composed of dichasial cymes. Flowers bisexual; terminal flowers solitary, larger and earlier flowering than the lateral ones. Tepals 5, free, often not contiguous at base, elliptic to ovate, c. 1 x 0.5 mm, sometimes purple, often whitish in fruit, weakly keeled, on the back with short-stalked glands and rarely a few sessile ones; margin membranous, glabrous; apex acuminate. Stamens 1-5. Stigmas 2(-3), 0.6-1 mm. Nut mostly falling without the perianth; pericarp not adherent to the seed. Seed horizontal, orbicular in outline, 0.7-0.8 mm; edge rounded (sometimes partly truncate); seed-coat black, almost smooth. - Autumn.
