The gingers are rhizomatous perennial herbs, mostly aromatic, of the family Zingiberaceae which has over 1500 species, with its center of diversity in Asia. It is the largest family in the order Zingiberales, which contains nearly 3000 species. The gingers are related to the Bananas, Strelitzias (Bird-of-paradise flowers), Orchidanthas, Heliconias, Costus (Spiral Gingers), Cannas, and Prayer-plants. In Borneo, the gingers display great diversity and are separated into 19 genera with nearly 250 named taxa (and many others still to be identified). They favor riverine and limestone forests, but occur from lowland coastal forests to as high as lower montane forests; only a few occur in upper montane forests.
Many ginger species – and 4 of the 19 genera – in Borneo are endemic to the island, which is one of the world's hotspots of plant diversity; this is also true for ginger diversity. While some gingers provide spices such as ginger, galangal, turmeric, and cardamom, other species are utilized as vegetables or for fruits, and many have medicinal uses. Though most have flowers that last only a day, the showy inflorescences produce a series of flowers for several days. These and species with beautiful foliage have potential as ornamental plants. A Guide to Gingers of Borneo covers 100 species, representing all 19 genera of Borneo.
