Phalaenopsis rundumensis

A Bornean moth orchid from Sabah, first collected in forest at 600-800 m and named after the Rundum area in the southwest of the state. It belongs to the P. gigantea / P. doweryensis group, carries two or three broad leaves 20-23 cm long, and produces successive small clusters of 2-3 flowers about 6 cm across on a slowly lengthening inflorescence, with very variable colouring. Grow it as a warm, shaded, humid epiphyte much like its better-known relatives.

Where it grows wild

An epiphyte of humid hill forest in Sabah. Published details are limited to the type locality near Rundum and an elevation of 600-800 m; like its relatives P. gigantea and P. doweryensis it presumably grows on trunks and branches in the shaded lower to middle canopy.

Collected at 600-800 m; warm hill forest, a little cooler at night than the lowlands.
