Ecology Minute epiphyte on Diospyros sp. & Mememceylon umbellatum in evergreen forest
Pseudobulbs 3-12 mm across, flat, irregularly. orbicular, usually in 3's forming a chain on tree trunks; veins usually running the whole length of the pseudo bulbs, rarely branching.
Leaves sessile, appearing usually before the flowers, often persistent till flowering, 2-3, arising from a pseudo stem 2-3 mm high, lamina 2-25 X 2-11 mm, obovate-elliptic or oblong to obovate, glabrous, 7-9-nerved, tapering to tl1e sheathing base, rounded apiculate at apex, margins entire, minutely papillate.
Scape 1-4 cm long, from between the leaves, sheathed at base, flexuose, capillary, bracteate at every bend.
Bracts 1-2 mm long, broadly ovate, cordate, cymbiform, acute or apiculate or acuminate, semi-amplexicaul, hyaline, entire, about as long as the ovary.
Flowers up to 12 in a raceme, each 2 mm long, subsessile, bracteate, translucently greenish white; generally only 1-2 flowers mature at a time.
Sepals ± equal; dorsal one 2 x 1.25 mm, oblong, entire, obtuse, 1-nerved;
lateral sepals 2 mm long, 1.5 mm broad at· base, subfalcate, obtuse or apiculate ; midnerve prominent, lateral pair of nerves indistinct.
Mentum stout, saccate, about equalling the upturned tips of the sepals.
Petals 1.25 x 0.75 mm, shorter than sepals, 1-nerved, narrowly oblong or sublanceolate, acute, broadest about the middle, entire.
Lip 1.5 mm long, very slightly stipitate, arcuate, oblong-ligulate, apiculate, ± equal to petals, fleshy, olive-green, enclosed within the much longer sepals.
Column very small with 2 small hook-like arms; foot 1.25 mm long, curved, stout.
Ovary about 1 mm long, oblong, with a very short pedicel.
Capsules 5 x 1.5 mm, broadly ovoid, green, faintly ribbed.
