The Plants Description
The rhizomes grow to 50cm long and branch many times. The pseudobulbs are spaced 9cm apart and 4.7cm long. The leaves are petiolate; the petiole measures 1.0cm long. The leaf blades are shaped lanceolate-elliptic and have acute apices. The leaf blades measure 9cm and 2.85cm wide.
The Inflorescence
The inflorescence grows from nodes found along the rhizome. The peduncle is covered with small bracts; the bracts are covered with red-brown spots. The inflorescence measures up to 10cm long. The flowers are spaced 3mm apart along the rachis.
The Flowers
The flowers are coloured light green and open widely. The flowers measure 8.5mm across. The sepals and petals are a few hairs on them. The dorsal sepal is incurved in the middle and recurved at its apex. The lateral sepals are convex, shaped obliquely ovate, apiculate and are 5mm long and 2mm wide. The petals narrow at their base are shaped obliquely lanceolate and are recurved at their apex. The labellum is very small and measures 2.4mm long. The labellum has a broad base and the epichile narrows abruptly. There are two raised ridges on the labellum. The column is curved and measures 2.6mm long. The apical hood is minutely bidentate and recurved. The stelidia grow from just below half way up the column and don’t quite reach the apical column.
