Commentaires

Notes: This species is related to G. rosea (Perrier) Ormd. with which it shares characters such as a densely flowered inflorescence and flowers with a bicarinate labellum that has a basal transverse row of dentiform calli. From G. rosea it differs in its smaller plant size (19.3 vs. 30-40 cm tall), shorterinflorescence peduncle (5.8 vs. 10-12 cm) and labellum with an obcuneate-subquadrate (not ovate) epichile. Another close relative is G. perrieri (Schltr.)Schltr. which also has a bicarinate labellum. However it differs from G. goudotii in having a laxly 8-12-flowered inflorescence with flowers in which the labellum has two parallel (not transverse) crests of subulate calli and a triangular (notobcuneate-subquadrate) epichile.
