The rhizomes branch and measure up to 50cm long with internodes spaced 3.5cm apart. The pseudobulbs are spaced 12.5cm apart and are cylindrical measuring up to 2.9cm long. The leaves are petiolate; the petiole measures 1cm long. The leaf blade is shaped elliptic-lanceolate. The leaf blade narrows abruptly 2cm from the apex. The leaf blade measures 14cm long and 3.5cm wide.

The inflorescence is synanthous and appears just before the leaves develop. The peduncle measures 5cm long and the rachis up to 10cm long, the rachis is arching. The flowers are spaced 3.5mm apart.

 

The Flowers

 

The flowers open widely and are light brown with a dark brown labellum. The sepals are shaped lanceolate and have acuminate apices. The sepals measure 6.5mm long and 1.75mm wide. The petals are shaped elliptic-lanceolate. The petals measure 6mm long and 2mm wide. The petals have erose margins along their upper part. The labellum is held parallel to the column and is 3-lobed. The side-lobes are small and broad. There are 3 keels that run nearly the entire length of the labellum. The column is very small and measures 1.3mm long. The apical hood has a bi-dentate margin. The stelidia grow from just above the middle of the column. The stelidia are shaped  linear and exceed the apical hood.

Additional Comments
