The Plants Description

 

The pseudobulbs cluster along the rhizome. The pseudobulbs are shaped cylindrical to slightly fusiform. The pseudobulbs measure up to c8.0cm long. The leaves are petiolate; the petiole measures up to c15.0cm long. The leaf blades are shaped narrowly-oblong and have acute apices. The leaf blades measure up to c30.0cm long and up to c3.0cm wide.

 

The Inflorescence

 

The inflorescence is synanthous. The peduncle is suberect and is longer than the rachis. The rachis is arched to nodding and measures up to c60.0cm long. The flowers alternate distichously and are flattened along the rachis. The rachis twists slightly.

 

The Flowers

 

The flower colour is white with reddish coloured sepals and petals, the tepals are white at their bases. The labellum is yellow and has orange markings on the inside of each side lobe. The sepals and petals do not open widely. The dorsal sepal is shaped narrowly-oblong and has an acuminate apex. The dorsal sepal measures c10.0-10.1mm long and c2.5mm wide. The dorsal sepal is three? veined and has entire margins. The lateral sepals are connate, shaped narrowly-oblong and have acuminate apices. The lateral sepals measure c9.9-10.0mm long and c2.0mm wide. The lateral sepals are three? veined and have entire margins. The petals are shaped narrowly-oblong and have acuminate apices. The petals measure c6.0-7.0mm long and c2.0mm wide. The petals are three? veined and have entire margins. The labellum is porrect, firmly attached to the column and is 3-lobed. The side lobes are erect, shaped semi-elliptical and have subacuminate apices. The mid-lobe is shaped oblong and has an acuminate apex. The labellum measures c8.3mm long. The labellum has entire margins. There are two long keels that emerge from the base of the labellum and terminate at the base of the mid-lobe. The column is suberect, straight and measures 3mm long. The apical wing is prolonged, distinctly exceeds the anther cap and is shaped truncate with a dentate margin. The stelidia grow upwards from the middle of the column. The stelidia are shaped broadly-obovate and have acuminate apices. There is a brown marking on the inside of each of the stelidia. The rostellum slightly protrudes but is overshadowed by the prolonged apical wing.
