Evolution

The earliest known fossils of the family belong to the Campanian age and are from the genera Spirematospermum in Germany,Tricostatocarpon and Striatornata in Mexico, and Momordiocarpon in India.[5][6] Spirematospermum chandlerae from the Santonian of North Carolina was previously classified in the Zingiberaceae, but more recent studies support it belonging to the Musaceae.[7][1]

Description

Members of the family are small to large herbaceous plants with distichous leaves with basal sheaths that overlap to form a pseudostem. The plants are either self-supporting or

zygomorphic, in determinate cymose inflorescences, and subtended by 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.[citation needed

Some genera yield essential oils used in the perfume industry (Alpinia, Hedychium).
