The petiole is 2-4 cm long while stipules are absent.

Inflorescence is terminal or axillary, usually solitary, 4-5 cm long, at first dense and scorpioid, ultimately lax and almost straight. Flowers are bisexual, 5-merous and subtended by orbicular-obovate 5-9 mm long bracts. The sepal tube is 4-5 mm x 3 mm, sparsely pilose, unequal lobes which are ovate to orbicular, 2-2.5 mm long.  Petal is 3 mm long with short tube, spatulate-obovate lobes and slightly fleshy. The stamens are alternate with petal lobes. Ovary is inferior with 2-celled, short style and massive stigma.  

Fruit is an ellipsoid, 8-9 mm x 3-4 mm indehiscent berry and many-seeded.

Seeds are ovoid and minute.
