Descriptions

de Kok, R. (2008). The genus Vitex (Labiatae) in the Flora Malesiana region, excluding New Guinea. Kew Bulletin 63: 17. https://doi.org/10.1007/s12225-007-9013-7

Distribution
New Guinea north to South China and west to India. New Guinea via Indonesia and Philippines to South China and India.
Ecology
Primary to secondary forest or more rarely in submontane forest, often in swamps or periodically inundated areas. Soil: stony to sandy or loamy clay, sometimes over limestone, at 10 – 470 (– 1000) m altitude. Flowering from May to December; fruiting from July to April. Lowland primary to secondary rainforest on (stony to sandy) clay or limestone at 10 - 470 m altitude.
Note
The leaves of Vitex quinata can vary enormously in texture throughout its range. Usually the leaves have an herbaceous texture, which is very similar to most other species of Vitex. However, populations do exist that have much more leathery leaves. These populations are usually in areas with a more monsoonal type of climate. The name of V. padangensis Hallier f. is based on examples of the latter type from Sumatra. Vitex buddingii Moldenke is based on a specimen with an inflorescence without any flowers or fruits; despite this, given the location and the shape of the inflorescence it clearly is part of V. quinata. This species differs from the widespread Vitex cofassus in having usually palmate leaves, calyces that are as velutinous as the inflorescence apex, and a corolla lip with a truncated apex. Vitex cofassus always has an unifoliolate leaf, calyces that are clearly less hairy than the inflorescence, and a corolla lip that is clearly emarginate. The indumentum character can sometimes be difficult to interpret when dealing with old inflorescences. Some specimens (e.g., Mair, April 1945) only have one leaflet per leaf and are then very reminiscent of V. cofassus. However, they have all the other above-mentioned characters in common with V. quinata, and are therefore better placed in this species.
