Origin in the Wild




Elevation in the Wild


665–1,030 metres


Habitat in the Wild


This species is an epiphyte of mossy cloud forest. The specimen, 12436 at Ames, was collected “in creeping clumps along small stems only a few feet from the moist humus covered soil of a forested ridge”


Plants have been collected from Mount Madia-as, the summit of Mount Salibongbong and Mount Guiting-Guiting on Panay.


The Plants Description


The pseudobulbs cluster on a short rhizome and are shaped fusiform to slenderly obpyriform. The pseudobulbs measure 0.7-2.6cm long and 0.2-0.6cm in diameter. The pseudobulbs are dark green. The pseudobulbs are covered with 3-4 cataphylls when they are growing; the cataphylls disintegrate into persistent fibres as the pseudobulb mature. The leaves are petiolate; the petiole measures 0.5-3.6cm long. The leaf blades are dorsiventrally complanate, shaped lanceolate and have acute apices. The leaf blades measure 5.0-13.5cm long and 0.8-1.6cm wide. The leaf blades are dark green above and pale green below. The leaves are thin textured to leathery and have 3-5 distinct nerves; the mid nerve is more prominent.


The Inflorescence


The inflorescence is synanthous. The peduncle is sub-erect to curved and measures 5.1-14.4cm long. The rachis is probably pendent and measures 5.4-13.4cm long. The flowers alternate distichously and are spaced 2.0-3.0mm apart. The peduncle is pale green and the rachis is reddish-brown. There are 3-6 appressed non floriferous bracts at the base of the rachis. The bracts are reddish brown. The flowers open from the proximal section of the rachis.


The Flowers


The flower is pale greenish-yellow. The sepals and petals spread widely. The dorsal sepal is shaped lanceolate and has an acuminate to acute apex. The dorsal sepal measures 4.8-5.9mm long and 1.6-1.8mm wide. The dorsal sepal is three veined and has an entire margin. The lateral sepals are shaped elliptic and have acuminate apices. The lateral sepals measure 4.8-5.8mm long and 1.9-2.1mm wide. The lateral sepals are three veined and have entire margins. The petals are shaped elliptic and have acute to obtuse apices. The petals measure 4.2-5.2mm long and 2.1-2.4mm wide. The petals are three veined and have finely erose (in the apical part) margins. The labellum is pendent and 3-lobed. The labellum measures 3.5-4.1mm long and 1.7-2.2mm wide. The labellum is 3-5 veined and has erose margins from the base to the apices of the side lobes, the mid-lobe margin is entire. The side lobes spread, are shaped triangular and have acuminate apices. The mid-lobe is shaped obovate to obcuneate and has a rounded and apiculate apex. There are two interconnected keels located on the lateral nerves and which terminate just past the base of the mid-lobe. The column is erect, slightly incurved and measures 2.3-2.8mm long. The apical wing is prolonged into a truncate to tridentate apex. The apical wing distinctly exceeds the anther cap. The stelidia grow upwards from the base of the column and are distinctly shorter than the column apex, the stelidia outcurve apically. The stelidia are shaped linear and have subacute apices. There are minute papillae on the lower margin of the stelidia.

Flowering Season


Flowering plants have been collected in the wild from April to June and during August.




I do not think this species is in cultivation or if it is it could be mislabelled as Dendrochilum uncatum or one of its synonyms.

Additional Comments


This species is similar to Dendrochilum uncatum but differs by its acute leaves, basally interconnected keels on the labellum and the acute, apically outcurved, minutely papillate stelidia. Henrik Pedersen (Pedersen 1997) considered this species to be closely related to Dendrochilum uncatum.


The epithet comes from parvus (small) and papillatus (having papillae on the stelidia)
