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

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

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

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.
