Continuing literature and herbarium studies of the Malesian orchid flora reveal the need for four transfers, viz. Aeridostachya bancana, Bryobium consanguineum, Phreatia microscopica, and Zeuxine zollingeri. Two taxa, Dendrobium lancifolium and Eria stellata are reinstated. Furthermore, aside from lectotypifications, nine new synonyms are proposed in the genera Bulbophyllum, Dendrobium, Eria, Gastrochilus, and Habenaria.
