Gmelina is a genus of approximately 35 species of flowering trees and shrubs in the family Lamiaceae (the mint family), placed in the order Lamiales. The genus is native to tropical and subtropical regions of Australia, Southeast Asia, India, New Guinea, and New Caledonia, spanning a range from the Indian subcontinent eastward through the Pacific island groups.
Members of the genus are woody plants — mostly trees or large shrubs — bearing opposite leaves, tubular two-lipped flowers, and aromatic characteristics broadly associated with the Lamiaceae. The genus includes both forest-canopy trees and smaller understorey species distributed across the Indo-Pacific region.
The most economically prominent species is Gmelina arborea, commonly known as Gamhar, White Teak, or Kashmir Teak, a fast-growing timber tree widely planted for pulpwood, construction timber, and agroforestry throughout tropical Asia and Africa. Several other species are confined to island archipelagos of the southwest Pacific, including New Guinea, New Caledonia, and the Solomon Islands. The genus was named by Carl Linnaeus in honour of the German botanist and explorer Johann Georg Gmelin (1709–1755).
Etymology
The genus name Gmelina was given by Carl Linnaeus in honour of Johann Georg Gmelin (1709–1755), a German botanist and naturalist renowned for his explorations of Siberia and his contributions to the study of flora across Asia.
Distribution
Gmelina species are native to a broad Indo-Pacific range encompassing India, Southeast Asia (including the Malay Peninsula and the Philippines), New Guinea, Australia, and New Caledonia. Some species, notably G. arborea, have been widely introduced beyond this native range and have become naturalised in parts of Africa and elsewhere in tropical Asia.
Taxonomy Notes
Gmelina belongs to the family Lamiaceae (order Lamiales). The genus was revised by de Kok in 2012, drawing on additional sources including IPNI, APNI, and the Flora of China. Earlier classifications sometimes placed it in the related family Verbenaceae, which accounts for conflicting records in some databases.
