Zingiberaceae (/ˌzɪndʒɪbəˈreɪsiː/) or the ginger family is a family of flowering plants made up of about 50 genera with a total of about 1600 known species[2] of aromatic perennial herbs with creeping horizontal or tuberous rhizomes distributed throughout tropical Africa, Asia, and the Americas.

Many of the family's species are important ornamental, spice, or medicinal plants. Ornamental genera include the shell gingers (Alpinia), Siam or summer tulip (Curcuma alismatifolia), Globba, ginger lily (Hedychium), Kaempferia, torch-ginger Etlingera elatior, Renealmia, and ginger (Zingiber). Spices include ginger (Zingiber), galangal or Thai ginger (Alpinia galanga and others), melegueta pepper (Aframomum melegueta), myoga (Zingiber mioga), korarima (Aframomum corrorima), turmeric (Curcuma), and cardamom (Amomum, Elettaria).

Characteristics

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 epiphytic. Flowers are hermaphroditic, usually strongly 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.

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

Distribution

The Zingiberaceae have a pantropical distribution in the tropics of Africa, Asia, and the Americas, with their greatest diversity in Southeast Asia.
