Assam Boat-Lip Orchid is a large sized, warm to cool
growing terrestrial orchid with an often branched, thin, woody stem.
Flowers are not upside down, greenish white; flower-stalk and ovary 5-6
mm. Sepals are lanceshaped or oblong-lanceshaped, 7-10 x 1.5-1.7 mm,
tip long tapering; lateral sepals fused only at base, tip recurved.
Petals are oblong-lanceshaped, 6-8 x about 1.3 mm; lip
ovate-lanceshaped or oblong-lanceshaped, boat-shaped, 6-8 mm,
concave-saclike at base. It has basally stem-clasping, thin but tough,
pleated, narrowly lanceshaped, pointed leaves. Leaves are held in a
spiral around the stem. The plant blooms in the late spring and early
summer on a 1.5 cm long, corymb-like, several to many flowered
inflorescence, in leaf-axils or at branch-ends, often on more than one
per internode. Assam Boat-Lip Orchid is found in Eastern Himalayas
to New Caledonia, Peninsular India and Andaman islands. It grows in
shaded places, along valleys in forests, at altitudes of 200-1000 m.
