Province, Luzon. 
This species has the appearance of Eria perspicabilis Ames 
but is most closely allied to E. brachystachya Reichb. f. and to 
E. albolutea Rolfe. It is larger throughout than E. brachysta¬ 
chya with a rather different lip. It has much larger leaves, 
fewer-flowered racemes, and apparently wider perianth parts 
than E. albolutea Rolfe.
