The Plants Description

 

The rhizomes are ascending. The pseudobulbs are shaped narrowly ovoid, almost terete. The pseudobulbs measure 4-5cm long and 1cm in diameter at the base. The leaves are petiolate; the leaf blade is shaped lanceolate with an acute apex and measures 12-18cm long and 2-2.5cm wide.

 

The Inflorescence

 

The inflorescence is pendent. I could find no other information.

 

The Flowers

 

The flowers are approximately 4mm across and are whitish-green. The sepals and petals look much the same and are shaped ovate-lanceolate with acuminate apices. The labellum is entire shaped obovate with an apiculate apex. The labellum is 2mm wide. The labellum has a transversely bilobed ridge at its base; there is a semicircular callus on the upper third of the labellum. The labellum is densely hairy. The column is small and the apical hood is tridentate. The stelidia grow from the top 1/3 of the column and are subulate.

Other Information

 

Kränzlin compared this species to Dendrochilum filiforme but Jim Comber wrote that the labellum on Dendrochilum barbifrons is very different (Comber 2001). This species is distinguishable by the dense hairs on it labellum.
