Morphology Reproductive morphology Inflorescences
Inflorescences usually bisexual in the axils of the upper leaves, or in the axils of fallen leaves just above soil-level, single, paniculate, but with very reduced side-branches so the inflorescences appear as interrupted spikes, of an overall length up to 30 cm., often with clusters of flowers from the base, but sometimes with a peduncle up to 10 cm. long, axis glabrous or puberulous, flowers in cymose clusters up to 1 cm. in diameter.
