Common Name The Ribbed Micropera
Flower Size .52" [1.3 cm]
Described from an inflorescence only, that was found in western Sumatra at unknown elevations, with a non-branched, peduncle terete, to 3.2" [8 cm] long, rachis a bit thicker and angular, many flowered, and carrying fleshy, mostly waxy yellow flowers that face in all directions
J J Smith stated that this species differed from M papuana in the lip shape, the ribbed spur and the twisted column. It differs from M proboscidea in the lip shape and the shorter rostellum and it differs from M callosa in the broader floral segments, the lip shape and the much longer rostellum.
CAUTION The first photo seems much closer to J J Smith's type drawing, the second and third photo are close but as you can see in the side view photo, there are erose margins to the midlobe of the lip that are not present in J J Smith's drawing
Synonyms *Camarotis costulata J.J.Sm. 1927
