The Plants Description

 

This species can reach a height of 55cm. The pseudobulbs are spaced close together on a short rhizome. The pseudobulbs are shaped oblong and are almost cylindrical. The pseudobulbs measure 2-2.5cm long and 4-6mm in diameter. The leaves are petiolate, the petiole measures 1-4cm long. The leaf blades are shaped narrowly lanceolate and measure 15-30cm long and 1.5-2.4cm wide.

 

The Inflorescence

 

The inflorescence is synanthous and grows at the same time as the leaves. The peduncle measures 13-17cm long and is erect.

 

The Flowers

 

Between 10 and 20 flowers are recorded as growing on an inflorescence. The flowers measure 1cm across and are greenish-yellow. The dorsal sepal is shaped lanceolate and has an acuminate apex. The dorsal sepal measures 5.5mm long. The lateral sepals are shaped oblique and have acuminate apices. I could not find any information about the measurements of the lateral sepals or petals nor about the shape of the petals. The labellum is 3-lobed and measures 4mm long and 3mm wide. The side lobes grow from the base of the labellum and are ear shaped, oblique and have shortly acute apices. The mid-lobe is shaped broadly elliptic and has an acuminate apex. There are 2 small keels close to the labellum’s base. The column measures 2mm long and the apical hood has a dentate margin. There are no stelidia.

Other Information

 

J.J. Smith thought that this species and Dendrochilum kingii could be the same (Comber 2001). Schlechter also wrote that this species was close with Dendrochilum kingii but differed by having no stelidia or even swellings on the column, smaller flowers and acute side lobes. The side lobes on D. kingii are obtuse.

 

I find it unusual that this species has been placed in section Platyclinis as there are no stelidia.
