Characteristics

Shrub about 2 m tall which may become scandent if crowded with other trees or bushes; young branches very delicate, sparsely pubescent, soon becoming glabrous, older branches 4-angled. Leaf-blade 15-60 x 8-25 mm, lanceolate, apex acute to subacute, base rounded or subcordate, margin serrate or serrate-crenate, glabrous above, very sparsely appressed stellate-pubescent below, especially on the nerves, lateral nerves 4-5; petiole 1-3 mm long, sparsely setulose-pubescent; stipules about 6 mm long, subulate, sparsely setulose. Inflorescences all axillary; peduncles 3-10 mm long, 1-3-flowered, slender, sparsely setulose; pedicels similar, 2,5-6 mm long; basal bracts 1 mm long, minutely pubescent, oblong. Buds oblong, slightly wider towards the apex. Sepals about 6.5 mm long, narrowly oblong-spathulate, involute towards the apex, pubescent outside, three-nerved, apex somewhat hooded. Petals yellow, about half the length of the sepals, often incised at the apex, with a basal nectary which is circumvillous on the margins within with a slight ledge above and glabrous at the back. Androgynophore 0.75 mm long, glabrous, barely elongated at the pubescent apex. Ovary never lobed, appressed setose; style about 3 mm long, glabrous; stigmas very small, subulate. Fruit about 8 mm in diam., globose, yellowish, very sparsely stellate-setulose.
