The Plants Description

 

The rhizomes branch. The pseudobulbs are shaped cylindrical and are narrowed toward the apex. The pseudobulbs are pale green and measure 3.5cm long and 6.5mm in diameter. The leaves are petiolate; the petiole measures up to 3cm long. The leaf blades are shaped linear and have acute apices, narrowed towards the apex. The leaf blades measure 15cm long and 8.5mm wide.

 

The Inflorescence

 

The inflorescence grows from the apex of the pseudobulb just before it matures. The peduncle is erect and measures 12cm long. The rachis measures 4.5cm long. The flowers are spaced 1.5mm apart.

 

The Flowers

 

The flowers measure 3mm across and are pale green with a greenish yellow labellum.  The dorsal sepal is shaped narrowly ovate and has an acuminate or acute apex. The dorsal sepal measures 2.5mm long and 1.25mm wide. The lateral sepals are shaped obliquely ovate and have apiculate apices. The lateral sepals are shorter than the dorsal sepal. The petals are shaped obliquely oblong. The petals measure 2.3mm long and 1mm wide. The petals have erose margins. The labellum is entire and measures 2.25mm long. The labellum is shaped oblong-ovate and has a truncate apex. There are two incurved margins at the base of the labellum and two keels that run between them. The column is very short and measures 0.75mm long. The apical hood is elongate and as long as the column. The stelidia are very small and triangular.

J.J. Smith compared this species with Dendrochilum cornutum and wrote that it differs because the leaf, flowers, rachis and the lateral wings on the column are smaller (Comber 2001).
