The Plants Description

 

The pseudobulbs are placed close together on a short rhizome. The pseudobulbs are shaped long-ovoid and narrow abruptly at their apices.  The pseudobulbs measure c3cm long and c0.8cm in diameter. The leaves are petiolate; the petiole measures 2.2-4cm long. The leaf blades are shaped linear-lanceolate and measure c21cm long and c1.4mm in diameter.

 

The Inflorescence

 

The inflorescence is synanthous and grows from the immature pseudobulbs before its leaf has fully developed. The peduncle measures 12-17.5cm long. The rachis is zig-zag and measures approximately the same length as the peduncle. The flowers are spaced c4mm apart.

 

The Flowers

 

The small flowers are a salmon colour. The dorsal sepal is shaped oblong-ovate and is narrowed towards its recurved apex. The dorsal sepal measures c4mm long and c1.75mm wide. The lateral sepals are shaped oblique and have acute apices. The lateral sepals measure c4mm long and c1.75mm wide. The petals are shaped obliquely-oblong and have acute apices. The petals have tiny trichomes above and the margins widen basally. The labellum is 3-lobed and strongly convex. The labellum measures c3.25mm long and c2.6mm wide. The side lobes grow from near the base of the hypochile are rounded and concave. The mid-lobe is shaped triangular and is narrower basally, its margins incurve. There are scattered trichomes on the labellum. The column is curved and measures c1.3mm long. The apical hood is shaped semi-orbicular and has an irregular dentate margin. The stelidia grow from the middle of the column, are shaped obliquely linear and do not reach the column apex.
