Leaves entire alternate, often approximated in pseudo-verticels. Lamina up to 7,5 x 2,8 cm, usually 2-3 x 1-1,2 cm, narrowly to broadly elliptic or obovate-elliptic, usually acute, rarely rounded at the apex, cuneate at the base, appresed-pubescent and minutely verruculose, appresed-pubescent (often densely) beneath, midrib often sericeous beneath; lateral veins 4-7 pairs, reticulation often rather conspicuous beneath. Petioles 2-8 mm long, slender, appresed-pubescent. Inflorescences composed of 3-7 flowers grouped in a subcapitate spike on a slender sericeous rachis up to 2,5 cm long, usually 1-1,5 cm long; spikes usually borne in clusters of 2-5 on dwarf shoots or singly in the axils of the leaves. Flowers sessile, pentamerous, yellowish. Upper receptacle cupuliform, 2-2,5 mm long, appresed-pubescent. Lower receptacle 2-3 mm long, sericeous. Calyx-lobes ovate-triangular, about 1 mm long.
