Erect Coelogyne is an orchid growing on trees, with
comparatively large sized cylindric, smooth pseudo-bulbs, sheathed at
the base, as long as 6-13 cm and 4-6 cm in diameter. Bulbs are attached
at a distance more than 4 cm apart on very stout sheathed rhizomes.
Leaves are in pairs, slightly leathery, elliptic oblong, pointed,
narrowed at the base to a long leaf-stalk. Leaves are as long as 15-25
cm and 2.5-4 cm in width. Flower-cluster-stalk arising between the
leaves from the tip of the adult bulbs, rather short or of the same
size of the leaves, naked on the lower portion, with many closely
arranged overlapping sheaths just below the raceme. Raceme is 7-10 cm
long, distichous, many flowered. Flowers are 2-4 cm across, sepals and
petals pale ochre, the lip white, the middle lobe with a broad wide
spot of yellow spread across and with two parallel purple streaks. The
flowers are of an unpleasant smell. Sepals are nearly equal, oblong,
sub-pointed, spreading, three veined. Petals very narrowed, slightly
longer than the petals, sub-pointed, single veined. Lip elongate, the
lower part oblong and with narrow entire side lobes, separated from the
sub-round anterior lobe by an erose edged sinus; anterior lobe
irregularly erose, wavy, blunt; the disc with two erose-crenulate
lamellae from the base to almost tip. Erect Coelogyne is found in
