NOTES

It is a tiny, pale green epiphyte with shoot width of only 0.4-0.8 mm. Specific characters are narrowly triangular lobes of the concave leaves with long, setose apices and with triangular, unicellular teeth on their side and also on the underleaves. It seems to be a rare Malesian species hitherto known only from Java and Papua New Guinea. New to Vietnam.
