The Plants Description

 

The rhizomes are short, branch and bear pseudobulbs close together. The pseudobulbs are shaped ovoid and measure 4-6.5cm long and 3mm in diameter. The pseudobulbs grow at an acute angel to the rhizome. The leaves are petiolate, the petiole measures 1-2cm long. The leaf blades are shaped linear and have acute apices. The leaf blades measure 14-16cm long and 5-8mm wide.

The inflorescence is synanthous. The peduncle is filiform, shaped terete and measures 12cm long. The rachis measures 5-5.5cm long. The flowers are spaced 2mm apart

Between 18 and 20 flowers grow on an inflorescence. The flowers are creamy yellow. The dorsal sepal is shaped lanceolate and has an acute apex. The dorsal sepal measures 4.7mm long and 1.3mm wide. The lateral sepals are shaped lanceolate and have acute apices. The lateral sepals measure 5.1mm long and 1.9mm wide. The petals are shaped lanceolate and have acute apices. The petals measure 3.8mm long and 1.3mm wide. The labellum is 3-lobed. The labellum side lobes are erect, shaped quadrangular and have acute apices. The side lobes measure 0.67mm long and 1mm wide. The mid lobe is shaped triangular and has an acute apex. The mid-lobe measures 2.5mm long and 1.3mm wide. The margins on the side lobes are erose. There are two keels that emerge from the base of the labellum and are connected by a transverse ridge at the middle of the labellum. The column measures 1.7mm long. The apical hood has a truncate apex with a dentate margin. The stelidia grow from above the middle of the column and do not reach the column apex. The stelidia are broad and have truncate apices.

Other Information

 

Jim Comber wrote that this species is similar to Dendrochilum dewildei but differs by its longer and narrower pseudobulbs, longer leaves, and inflorescences that roughly the same size or only slightly longer than the leaves, longer peduncle and shorter rachis and 3-lobed labellum with erose margins.
