Moore s.n. ( K ) ; Jun 1903 , cult. Moore s.n. ( K ) . Distribution:— The eastern Himalayas, northeastern India , Myanmar , Thailand and southwestern China . Notes:— Vanda confusa is based on V. coerulescens var. boxallii . In PO’s opinion, it is not a natural hybrid and definitely falls within the variability of V. coerulescens . Vanda parviflora var. albiflora looks more like a smallflowered form of V. coerulescens . It is probably not the same as V. lilacina Teijsm. & Binn. , for which no Myanmar material has been seen. Photographs identified as V. lilacina in Nyan Tun (2014: 451−452) seem to be V. coerulescens because they have the retrorse spur and relatively longer midlobe of that species.
