Erect terrestrial herb. Stem terete, laxly 9-leaved, rooting at base, 9.5 cm long, 0.15-0.3 cm thick; internodes 0.8-1.65 cm long. Leaves obliquely oblong to ovate, acute, 3.2-5.5 cm long,0.5-1.7 cm wide; petiole and sheath 1.1-1.6 cm long. Inflorescence pubescent, 9.8 cm long; peduncle 5.8 cm long; sheathing bracts three, approximate, 1.5-2 cm long; sterile floral bracts 6-7 at apex of peduncle, lanceolate, acute, crowded, to 1.1 cm long; rachis densely ca. 40-flowered, 4cm long; floral bracts lanceolate, acute, lcm long, 0.2 cm wide. Pedicellate ovary cylindric-fusiform, pubescent, 4-5mm long. Flowers resupinate, colour not known, externally pubescent in lower half. Dorsal sepal oblong-lanceolate, subacute, 4 mm long, 1.5 mm wide. Lateral sepals obliquely elliptic, acute, subfalcate, 4 mm long, 1.9 mm wide. Petals ligulate-oblanceolate, acute, 4 mm long, l mm wide.

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), shorter inflorescence 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 (not obcuneate-subquadrate) epichile.
