This species has been collected from Aceh Province on the summit of Mount Lembuh in the Gayo Highlands. The type was collected on a forest ridge.

 

The Plants Description

 

The pseudobulbs cluster together on a short rhizome. The pseudobulbs are shaped narrowly ovoid to oblong-ovoid and are a reddish colour. The pseudobulbs measure 1.5-2.2cm long and 3.0-4.3cm in diameter. The leaves are petiolate. The leaf blades are shaped narrowly linear and have more or less obtuse apices. The leaf blades measure 21-25cm long and c3mm wide. The leaves are rigidly coriaceous.

 

The Inflorescence

 

The inflorescence is synanthous and appears with the newly formed pseudobulbs. The peduncle is erect and measures 16-17.5cm long. The rachis measures 10-13cm long.

 

The Flowers

 

The dorsal sepal is concave, shaped narrowly lanceolate and has an acute apex which is apiculate in its centre. The dorsal sepal measures c6mm long and c1.5mm wide. The dorsal sepal is three veined and has entire margins. The lateral sepals are shaped obliquely lanceolate and have acute apices that narrow. The lateral sepals measure 6.3mm long and 1.5mm wide. The lateral sepals are 3-veined and have entire margins. The petals have acuminate to acute apices; I could find no other information on their shape. The petals measure c5mm long and 1mm wide. The petals are three veined and have erose margins basally. The labellum is three lobed and has an overall elliptic shape when spread out. The labellum measures 3.6mm long and 1.6mm wide. The labellum is three veined. The side lobes are broad and have fimbriate margins. The mid-lobe is shaped rhomboid and has a somewhat acute apex. The mid-lobe has serrate-erose margins except at its base. The mid-lobe measures c2mm long and 1.6mm wide. The column measures 2mm long. The apical wing is broad and bilobed, each lobe shaped triangular. The stelidia grow at an acute angle from the apical hood and curve inwards. The stelidia grow from just below the middle of the column and do not reach the column apex. The stelidia are shaped linear-subulate and have an acute apex.

Other Information

 

Jim Comber wrote that this species seems to be closest to Dendrochilum ophiopogonoides (Comber 2001). J.J. Smith wrote that the labellum resembles Dendrochilum linearifolium but also mentioned that in other respects it is quite different (J.J. Smith 1943).
