In this research 11 epiphyticorchids such as Bulbophyllum bakhuizenii Stenn, Coelogyne miniata Lindl, Coelogyne rochussenii de Vr.,
Dendrobium bigibbum Lindl., Dendrobchilum longifolium, Eria bogoriensis, J.J.S. Liparis caespitosa (Thou.) Lindl., Liparis pallida (Bl.). Pholidota globosa (Bl.) Lindl., Polystachya flavescens (Bl.)
