Brachyblast buds lanceolate; brachyblast usually developing a pair of normal leaves near base of the terminal 1(3)-flowered cyme, there being an outer involucre of scarious stipule-derived and leaf-derived bracts and an inner larger involucre of similarly derived bracts and bracteoles 2.5–10 × 2 × 4 mm, inside which the flower is subtended by a cupular bracteole sometimes with a subfoliaceous lobe.
Fruits yellow, yellow-orange or scarlet with greenish veins, or black (fide E.A. Robinson 6045), surrounded at the base by the imbricate bracts/bracteoles, 5 mm in diameter (dry), 7–8 × 8–9 mm (fide Lebrun), subglobose.
