3. This species is most closely allied to G. bambusifolia, but can be distinghuised by the comparatively narrower perianth parts and differently shaped spur and blade of the lip. This species is also smaller (not exceeding 20 cm in height) as compared to G. bambusifolia that can reach up to 65 cm high. This species is the only species of the genus Glomera that has been reported from Micronesia.
