The Plants Description

 

The pseudobulbs are narrow and shaped ovate. The pseudobulbs grow close together on the short rhizome and measure 2.5cm long. The leaves are petiolate; the petiole measures 6cm long. The leaf blades are shaped narrowly lanceolate and have acute apices. The leaf blades measure 30cm long and 1.5cm wide.

 

The Inflorescence

 

The inflorescence is synanthous and grows at the same time as the leaves.  The peduncle grows to 20cm long, the rachis to 15cm long. The flowers alternate distichously and in a zig-zag habit and are spaced 4.5mm apart.

 

The Flowers

 

Approximately 30 flowers grow on an inflorescence. The sepals are shaped narrowly triangular-lanceolate and have acute apices. The sepals are three veined and measure 8mm long and 2mm wide. The petals are shaped lanceolate and have acute apices. The petals are three veined. The labellum is entire and measures 5.7mm long. The hypochile is a circular shape and has erose margins. The epichile is shaped oblong-ovate and has finely erose margins. There are 2 short ridges on the hypochile. The column is curved and measures 2.5mm long. The apical hood has an obtuse apex. The stelidia grow from the middle of the column and do not reach the apical hood. The stelidia are shaped lanceolate.

I do not think this species is in cultivation, if it is which is doubtful, it could be labelled as Dendrochilum simile.

Other Information

 

Jim Comber wrote that this species appears to be close to Dendrochilum simile but differs by having erose margins on the hypochile and shorter stelidia (Comber 2001).
