Habitat in the Wild


This species has been collected from Mount Talang in Solok Province. I could find no information about its wild growing habits.


The Plants Description


The pseudobulbs are placed close together on the rhizome. The pseudobulbs measure 5.7cm long and are narrowed at the apices. The leaves are petiolate; the petiole measures 1.85-3.2cm long. The leaf blades are shaped elliptic-lanceolate and have obtuse apices. The leaf blades measure 14-17cm long and 4.3-6.3cm wide.


The Inflorescence


The inflorescence is synanthous and grows from immature pseudobulbs at the same time that the leaves emerge. The peduncle measures 12-17cm long. The rachis is quadrangular in cross-section. The flowers are spaced 4.5mm apart.


The Flowers


The flowers are green; the labellum has two brown longitudal markings. The sepals and petals are incurved and have papillae at their bases. The dorsal sepal is shaped oblong-rhomboid and has an acute apex. The dorsal sepal measures 7mm long and 2.6mm wide. The lateral sepals are shaped obliquely oblong-ovate and have acute apices. The lateral sepals measure 7mm long and 2.75mm wide. The petals are shaped oblong-ovate. The petals measure 6.25mm long and 2.3mm wide. The margins on the petals are erose near their apices. The labellum is hinged and recurved above its base and 3-lobed. The side lobes are broad and have narrowly triangular to acute apices. The side lobe apices have erose margins. The mid-lobe is shaped broadly spatulate and has a truncate and minutely apiculate apex. There are three keels that run the labellum’s length from the base of the hypochile and terminate by merging together on the mid-lobe. The median keel is smaller. The column is curved and measures 4mm long. The apical hood is triangular and has an acute apex with a dentate margin. The stelidia grow from below the middle of the column and are shaped obliquely linear. The stelidia curve inwards and grow as long as the column but do not reach the column apex.
