Shrub. Branchlets rather densely very shortly pubescent and patent-setulose, terete, brown-red when dry. Leaves ovate or oblong-ovate, apex shortly subacutely acuminate, the terminal gland small, base subcordate, subcoriaceous, glabrous above, the puberulous midrib excepted, rather densely short-setulose, finally punctate beneath, regularly serrulate, the teeth close, c. 0.5 mm, each ending in a fine caducous bristle, (2-)2.5-4.5(-5) by (1.5-)1.8-2.5(-2.8) cm, midrib and nerves very slightly impressed above or rather obscure, distinct beneath, midrib thick-prominent beneath, nerves 2-3 pairs, high curved-ascending and anastomosing, the lowest 1-2 pairs from, the upper ones from above the base of the lamina, other nerves or veins ± transverse from the midrib, forming with the veinlets a lax reticulation which is a little raised beneath; petiole pubescent, laxly setulose, rather flattened, 1.5-2 by 1-1.5 mm. Panicles terminal, formed by racemes which come from the axils of the upper, rather abruptly decrescent leaves, sometimes with additional racemes from the axils from lower and normal leaves, all racemes ± spreading, rather dense-flowered, slender, (4-)5-12 cm. Rachis 0.5-0.7 mm ø, densely shortly yellowish pubescent and laxly setulose especially in its lower part. Pedicels exclusively densely yellowish pubescent, c. 3 mm. Bract ovate, subacuminate, pubescent, 2-3 mm. Bracteoles subovate-semiorbiculate, pubescent, c. 1.5 mm, inserted immediately below the calyx. Calyx rather deeply 5-partite, 2.5 mm, short-pubescent dorsally, lobes ovate-acute, densely ciliate. Corolla subcylindric-urceolate, 4.5-5 by c. 2.5 mm, somewhat contracted at the mouth, glabrous. Stamens c. 2.5 mm; filaments papillose; anthers ovate-oblong, the very short tubules biaristate (c. 0.7 mm). Ovary whitish yellowish hirsute; style glabrous, 3 mm.
