The pseudobulbs are clustered along a rhizome. The pseudobulbs are cylindrical and slightly narrowed at their apices. The pseudobulbs measure 6.5cm long and 5.5mm in diameter. The leaves are petiolate; the petiole measures 3mm long. The leaf blades are shaped narrowly lanceolate and have acute apices. The leaf blades measure 16cm long and 1.25cm wide.

The inflorescence is synanthous. The peduncle is erect and measures 5cm long. The rachis is nodding and measures 8cm long.

 

The Flowers

 

The following is taken from Jim Comber, The Orchids of Sumatra.

 

The flowers are small and measure 6.3mm across. The dorsal sepal is shaped ovate and has an obtuse apex. The dorsal sepal measures 3.3mm long and 2mm wide. The lateral sepals are shaped obliquely-oblong and have acute apices. The lateral sepals measure 3.6mm long and 1.75mm wide. The petals are shaped elliptic and slightly oblique. The petals measure 3mm long and 1.7mm wide. The labellum is entire. The labellum is shaped broad almost ovate and slightly rhomboid, the labellum narrows slightly in the middle. The labellum apex is rounded. The labellum is 3mm long and 1.4mm wide. There are three keels at the base of the labellum that form a shape like a letter W. The column measures 1mm long; the apical hood has 2 or 3 teeth and is yellowish-white. The stelidia are only minute triangular teeth.

Additional Comments

 

This species is supposed to be similar to Dendrochilum cornutum but differs by its smaller flowers, the keels on the labellum that form the letter W and stelidia that are minute triangular teeth.
