The Plants Description

 

The rhizomes are long and creeping, Jim Comber wrote that this species hangs down from tree branches (Comber 2001). The pseudobulbs are cylindrical and measure 2-3cm long and 0.5-0.7cm in diameter. The pseudobulbs are narrower at their apex. The leaves are shaped elliptic-lanceolate and have very short petioles; the leaves measure 10-12.5cm long and 1.3-2.3cm wide.

 

The Inflorescence

 

The flowers grow all the way from the base of the inflorescence. The inflorescence measures 9-17cm long

 

The Flowers

 

The flowers are yellow and open widely. The sepals are shaped narrowly oblong and have subacute apices. The sepals measure 5mm long. The petals are shorter than the sepals and are shaped  linear-spathulate and falcate. The labellum is entire, shaped oblong and ahs an obtuse apex; the labellum is wider at its apex. The column measure 2mm long. The stelidia grow from near the apex and curve inwards, the stelidia are longer than the column.
