Habitat in the Wild

 

The holotype was collected at Kaba in Bengkulu Province. J.J. Smith wrote that this species was rather common in old forest (J.J. Smith 1943).

 

The Plants Description

 

The rhizome branches and hangs freely, the rhizome measures up to 60cm long and has internodes of 0.5-1.8cm. The pseudobulbs are spaced widely apart, shaped terete and measure 1.5-3.0cm long and 4-6mm in diameter. The leaves are petiolate; the petiole measures 0.4-1.0cm long. The leaves are shaped ovate-oblong to lanceolate and have shortly acute or apiculate apices. The leaf blades measure 5.5-12.5cm long and 1.2-5cm wide. There are 7-9 distinct nerves on the leaf blade.

 

The Inflorescence

 

The inflorescence grows from matured pseudobulbs, and is longer than the leaves. The peduncle measures 3.25-5cm long. The rachis measures 12-14cm long. The rachis is quadrangular in cross section. The flowers alternate distichously and are spaced 2.0-2.5mm apart.

 

The Flowers

 

I counted approximately 49 flowers on an inflorescence of the holotype. J.J. Smith wrote that the inflorescence is copiously flowered and the flowers are greenish-white (J.J. Smith 1943). The dorsal sepal is shaped lanceolate and has an acute apex. The dorsal sepal measures 4.5mm long and 1.5mm wide. The dorsal sepal has an entire margin and is three veined. The lateral sepals are shaped obliquely ovate-lanceolate and narrow towards their apex. The apices of the lateral sepals recurve. The lateral sepals have entire margins and are three veined. The lateral sepals measure 4.6mm long and 1.5mm wide. The petals are shaped ovate and have acute apices. The petals measure 3.6mm long and 1.8mm wide. The petals have erose margins and are three veined. The labellum is 3-lobed and three veined. The labellum measures 3.3mm long. The side lobes are short, recurved and contain minute trichomes. The mid-lobe is recurved, shaped ovate and has a narrowed acuminate apex. The mid-lobe contains minute trichomes. The mid-lobe measures 2.3mm long and 1.8mm wide. The column is very short and measures 1mm long. The apical hood is concave, tri-lobed and broadly obtuse. The stelidia grow from just below the middle of the column and are shorter than the column itself.

Additional Comments

 

J.J. Smith wrote (1943, Blumea p302) “Nearly related to D. decipiens J.J. Smith but differing by the smaller differently coloured flowers, more conspicuously erose petals, strongly recurved mid-lobe of the lip, relatively shorter lateral wings of the column, a broader stigma and rostellum. The sheaths of the rhizome are slightly punctuate light brown when young”.
