Conservation
This species must be considered as very rare. Only five collections are known, while relatives from similar habitats from the same area have been collected in abundance. Given that it has very few known localities and that Sarawak has gone through an extensive period of deforestation a conservation rating of vulnerable (VUB1) is proposed (IUCN 2001).
Distribution
Only known from a few collections from Sarawak.

Morphology Reproductive morphology Inflorescences
Inflorescence axillary, dichasia, compound, axis 1.4 – 2 cm long, flattened in cross-section; hairs few to moderate, appressed; glands many; bracteoles elliptic-lanceolate, up to 10 mm long, glabrous, often not persistent
Note
Vitex flava seems to be closely related to the Peninsular Malaysian species V. longisepala King & Gamble (see also Ridley 1929), but has more glabrous leaves with smaller bracts and a corolla, which is covered with glands rather than hairs. V. flava is endemic to Sarawak and is often confused with V. vestita Wall. ex Walp.
