Taxonomy

edit

The genus was erected by the Scottish botanist William Roxburgh in 1810, and published in the journal Asiatic Researches.[4] It is named after Prospero Alpini, a 17th-century Italian botanist who specialized in exotic plants.[5] Species of the genus are known generally as shell gingers.[3][6]

Description

edit

These herbs lack true stems, but have pseudostems usually up to about 3 metres (9.8 ft) long which are composed of the overlapping leaf sheaths.[2][3] A few species have been known to reach 8 metres (26 ft).[7] They grow from thick rhizomes. The leaves are lance-shaped to oblong. The inflorescence takes the form of a spike, a panicle, or a raceme. It may be hooded in bracts and bracteoles. The flower has a shallowly toothed calyx which is sometimes split on one side. The flower corolla is a cylindrical tube with three lobes at the mouth, the middle lobe larger and hoodlike in some taxa. There is one fertile stamen and two staminodes, which are often joined into a petal-like labellum, a structure that is inconspicuous in some species and quite showy in others. The fruit is a rounded, dry or fleshy capsule.[2][3] The plants are generally aromatic due to their essential oils.[8]

Species

edit

This is the largest genus in the ginger family,[7] with 248 species and 2 hybrids accepted by Plants of the World Online as of 27 June 2024.[1] A number of those are commonly grown for their flowers, including red ginger, and others are used as spices, including Galangal.
