Taxon name Zingiberaceae
Closely related taxa Costaceae Mobot.org
Taxon details Zingiberaceae split off from the genus Costaceae ~79 or ~100 million years ago, based on two estimates (Kress06,Janssen04). The family consists of over 93 genera and over 2000 different species, with the center of diversity in South-East Asia. Mobot.org,Kress06,Janssen04
Taxon morphology details Small to large herbaceous plants, distichous leaves with basal sheaths that overlap to form a pseudostem. Plants are either self-supporting or epiphytic. Flowers are hermaphroditic, usually strongly zygomorphic (bilateral symmetry), in determinate cymose inflorescences, with conspicuous, spirally arranged bracts. The perianth is composed of two whorls, a fused tubular calyx, and a tubular corolla with one lobe larger than the other two. Flowers typically have two of their stamenoids (sterile stamens) fused to form a petaloid lip, and have only one fertile stamen. The ovary is inferior and topped by two nectaries, the stigma is funnel-shaped. Wikipedia
