“ Staminate flowers 2-4 in a spathe, long-penduncled, the stamens united in a column bearing 6-12 anthers at different heights, sometimes producing only 9-12 staminodia, the filaments tipped with abortive anthers. Pistillate flowers sessile or short-peduncled with 3-6 vestigial stamens; ovary 6-9-celled with as many central placentae; stigmas as many as the cells, each 2-parted. ”
