Notes:

• this specimens collected from Rejang Lebong, Bengkulu Province, Indonesia
• "This species has been called E .rigida BL. in most accounts, Lindley's earlier naming having been overlooked until noted by Seidenfaden &J.J Wood in "The orchids of Peninsular Malaysia and Singapore" ( 1992 ). Schlechter noted that his E. rhodobractea differed from E. rigida in the lip, but this didifference has not been upheld by subsequent authors" ( Orchid of Sumatra, JB.Comber)
