Shrub, epiphytic, creeping. Branchlets rooting, red-brown and setose in the older parts, rather densely subpatently setulose (1.5-2 mm) and ± densely (rarely laxly) patently fuscous-puberulous. Leaves elliptic, sometimes subovate-elliptic or oblong-elliptic, broad-attenuate at both ends, the apical gland small though distinct, on each side accompanied by a protracted tooth, thus the apex becoming ± tridentate, rigid, coriaceous, glabrous above, set with scattered blackish, short ± caducous bristle-like hairs beneath, finally blackish punctulate, manifestly crenate, the teeth obtuse, passing into ± persistent bristles (1 mm), 0.7-1.4 by 0.4-0.7 cm, triplinerved, midrib distinctly sunken above, a little raised or sunken beneath, nerves impressed above, mostly obsolete, sometimes very slightly impressed beneath; petiole setulose, 1.5-2 mm. Flowers solitary. Pedicels slender, glabrous, (6-)7-10 mm. Bracteoles ovate, subacute, ± reflexed, rather long (0.6 mm) setulose. Calyx 2.5 mm, glabrous dorsally, lobes ovate-deltoid, 1.5 mm, margin with coarse longish (0.6-0.8 mm) bristles. Corolla urceolate, glabrous, bright red, 8.5-9.5 by c. 3.5 mm, lobes obtuse 1.5 mm. Filaments filiform, somewhat dilated above the base, S-curved, glabrous, 4.5 mm; anthers oblong, apiculate-recurved at the base, very granular, 3.5 mm, the rather broad tubules included. Ovary glabrous; style 7 mm.
