"Vine-like" shrub;  mature branches subterete, densely hispid with brownish to reddish-brown hairs 1-2 mm long.  Leaves oblong-elliptic, (8-)10-18(-20.5) x 3-7 cm, basally rounded or obtuse, apically somewhat abruptly caudate-acuminate, pilose on both surfaces (densely beneath) with brown hairs ca. 1-1.5 mm long, glandular-fimbriate on both surfaces;  5-plinerved from base with midrib and secondary nerves impressed above and raised beneath, reticulate veinlets obscure; petiole subterete, rugose, 5-7 mm long and 2.5-4 mm in diam., hispid as stems.  Inflorescence ca.20-flowered, the flowers restricted to distal 1/3 of inflorescence;  rachis subterete, densely pilose, 2.5-3.5 cm long and 4 mm in basal diam. becoming 7 mm in diam. at apex;  floral bracts subcoriaceous, conspicuously striate, oblong to obovate, 25-30 x 10-15 mm, apically obtuse or rounded, those of proximal 2/3 of inflorescence subtending sterile nodes, densely pilose dorsally, those of distal 1/3 subtending flowers and becoming continuously less pilose with margins glabrous, lamina of bracts also provided with subspherical, "granular" glands especially dense towards midrib;  pedicels subterete, sparsely pilose, 3-4 mm long and 1.5-2 mm in diam.;  bracteoles linear-oblong, ca. 7 mm long, margins (seemingly) eglandular and distally ciliate.  Flowers:  calyx essentially glabrous (except lobe margins), 9-12 mm long;  hypanthium obconic and slightly constricted just above base, 3-3.5 mm long;  limb cylindric-campanulate 7-8 mm long;  lobes narrowly triangular, 4-5 mm long with margins long-ciliate, eglandular, often involute;  sinuses rounded;  corolla not seen (although one style in the packet would suggest a corolla ca. 30 mm long);  stamens (from packet) alternately ca. 13 mm and 15 mm long;  filaments sparsely pilose on ventral surface, alternately 2.5-3 mm and 5-5.5 mm long;  anthers alternately ca. 11 mm and 10 mm long;  thecae nearly smooth 3-4 mm long;  tubules dehiscing by clefts 3.5-4.5 mm long;  style 30 mm long.  Berry not seen.
