Habitat in the Wild


This species is found in Aceh Province on Mount Leuser West and close to the summit. A specimen was recorded as growing as a dense tufted epiphyte on stunted trees.


The Plants Description


The pseudobulbs are shaped ovoid and have narrowed apices. The pseudobulbs measure 1.5-3.5cm long and 5-8mm in diameter. The pseudobulbs are placed at an acute angle to the rhizome and are pale green. The leaves are petiolate, the petiole measures 0.5-1cm long. The leaf blades are shaped narrowly lanceolate to ligulate and have acute apices. The leaf blades measure 5-9cm long and 5-7mm wide. The leaf blades are dark green.


The Inflorescence


The inflorescence is synanthous. The peduncle is filiforme and measures 5-6cm long. The rachis measures 6-10cm long. The flowers are spaced 2.5mm apart.


The Flowers


Up to 40 flowers are recorded by Jim Comber as growing on an inflorescence. The flower colour on the holotype is described as creamy. The dorsal sepal is shaped lanceolate and has an acuminate apex. The dorsal sepal measures 5.4mm long and 1.9mm wide. The lateral sepals are shaped oblong to narrowly triangular. The lateral sepals measure 5.4mm long and 1.9mm wide. The petals are shaped lanceolate and have acute apices. The petals measure 4.4mm long and 1.7mm wide. The labellum is porrect and 3-lobed. The side lobes are erect, shaped triangular and have acute apices. The side lobes measure 0.4mm long and 1.3mm wide. The mid-lobe is shaped narrowly triangular and measures 2.5mm long and 1mm wide. The labellum has entire margins. There are 2 keels that are connected at the base of the labellum by a transverse ridge, there is a smaller median keel. The keels grow from just above the labellum’s base and run nearly the whole length of the labellum. The column is wide and measures 2.3mm long. The apical hood has a truncate apex and a dentate margin. The stelidia grow from the middle of the column and do not reach the apical hood. The stelidia are shaped broadly obtuse.

Other Information


It appears the spelling of this name on the on-line Kew World Checklist of Selected Plant Families is incorrect.


Jim Comber wrote that this species is similar to Dendrochilum merapiense but differs because the flower colour is cream not brown, the keels are much longer, the side lobes have entire margins and the mid-lobe is wider basally.
