Description

Tetrameranthus laomae is a tree reaching 7 to 35 meters in height with a trunk diameter of 11 to 45 cm. Young twigs and petioles are densely covered with whitish, stellate hairs that become glabrous with age. The leaves have petioles 10 to 20 mm long and laminae that are obovate to narrowly elliptic-obovate, 6 to 24 cm long and 2 to 7 cm wide. The leaves are chartaceous to thinly coriaceous, with a shiny to dull greenish-brown upper surface and a dull greenish-brown lower surface in dry conditions. The primary vein is raised to almost flat above, with 7 to 10 secondary veins on either side, forming loops. Inflorescences are single-flowered, with peduncles up to 1 mm long and bracts 1 to 2.5 mm long. Flowers are green to yellowish with yellow centers or entirely yellow, and sepals are broadly elliptic to ovate, 2.5 to 3 mm long.
