Morphology Leaves
Leaves somewhat fleshy, digitately 3–5-foliolate, sessile or nearly so; leaflets narrowly obovate, narrowly elliptic, ovate-elliptic or elliptic, 3–11 cm. long, 1.2–4.3 cm. wide, obtuse to acute at the apex, cuneate to narrowly truncate or asymmetric at the base, crenate-serrate or serrate, sparsely puberulous when young but soon glabrous except for some hairs on the midrib above and glandular hairs beneath; median petiolules 0.5–2 cm. long, the laterals often obsolete or up to 5 mm. long; stipules obliquely ovate to ovate-lanceolate, 0.4–1 cm. long, 1.5–5 mm. wide, the margins with gland-tipped hairs.
Morphology Reproductive morphology Inflorescences
Cymes lax, terminating short lateral branches, up to 9.5 cm. long; peduncle 3–8 cm. long, glabrous to puberulous and sometimes with gland-tipped hairs; pedicels 2–4.5 mm. long, glabrous or puberulous; bracts and bracteoles lanceolate-acuminate, ± 2 mm. long, pubescent and with few marginal glands.
Morphology General Buds
Buds brownish or greenish yellow with red tip, oblong-cylindric, ± 2.5 mm. long, constricted above the middle, glabrous or rarely puberulous.
Morphology Reproductive morphology Flowers Calyx
