Ptychopyxis glochidiifolia Airy Shaw, Kew Bull. 14 (1960)

Latin for 'leaves similar to those of the genus Glochidion'.

The type of this species was collected in Sungai Wain in 1950, so it might still be alive in the forest.

Upper canopy tree up to 43 m tall and 76 cm dbh. Stipules absent. Leaves alternate, simple, penni-veined, glabrous. Flowers not seen but probably similar to the other two Ptychopyxis species in this checklist. Fruits ca. 14 mm long, yellow-reddish-brown, 2-lobed, fleshy capsules. Seeds probably with aril.

In undisturbed mixed dipterocarp forests up to 400 m altitude. Mostly on hillsides and ridges with sandy to clay soils. In secondary forests usually present as a pre-disturbance remnant tree.


Borneo (Sarawak, East-Kalimantan).
