Characteristics

Suffrutex up to 30 cm tall with a woody rootstock; stems upright, branched, cinnamon-coloured, cylindric, slightly striate, glabrescent at the base, ± villous at the apex. Petiole 0.3-1.8 cm long, slightly canaliculate or flat above, ± villous. Leaflets sessile, discolorous (ferruginous above, pale cinnamon-coloured below), not shining, papyraceous, with very slightly revolute margin, sparsely villous on both surfaces, a little more so on the nerves and margin; median leaflet 3.5-8 x 1.7-3.3 cm, broadly to narrowly elliptic, somewhat narrowed at the apex into a short cuspidate acumen, entire or with 1-3 mucronate-cuspidate teeth in the upper part, symmetric and cuneate at the base; lateral leaflets narrower and c. 1 /3 shorter than the median one, usually entire or sometimes also with few teeth, asymmetric at the base; midrib, lateral nerves and reticulation paler coloured than the lamina, prominulous on both surfaces. Panicles narrow, the axillary ones shorter, the terminal ones nearly as long as the leaves; axis, branches, bracts and pedicels (1 mm long) villous. Calyx-segments c. 1 mm long, ovate-lanceolate, sparsely villous to glabrous. Petals c. 1.5-2 mm long, oblong, obtuse. [Female] flowers and fruits not seen.
