is an evergreen perennial orchid occurring on trunks, bough, or even
twigs, emerging many roots at the plant base, which sustains the
body hanging down. The lanceolate, 2cm-long leaves are distichous,
arranging in two vertical rows. From the axil, there emerges a
slender stalk with yellow flowers. The sepals measure 7mm long, the
side petals a bit shorter, the lip sack-shaped with some
purple-brown spots inside.
