Notes.

Borneocola petiolatus is distinguished by its long petiole and narrow leaves from the other species. Its lamina length is almost 3 times the width (12-21.5 × 3.1-7.1 cm). Smith (1987) found that Borneocola petiolatus has small inflorescences as in Borneocola argenteus . However, both can be easily separated by their leaf characters. Borneocola petiolatus has much longer petioles compared to Borneocola argentea (12.7-31.5 cm versus 3-6 cm). Borneocola argenteus also has prominently raised lateral veins on the adaxial surface of lamina, more conspicuous on dried specimens than fresh materials. This character is lacking in Borneocola petiolatus .
