Habitat in the Wild
The type species was collected in Baram District in Sarawak. Nothing else is known of its habitat and I could not find any further information about it.
The Plants Description
The rhizome is long, creeping and can branch; the pseudobulbs are spaced approximately 1-2cm apart along it. The pseudobulbs measure 4cm long and are wider in their middle than at each end. The pseudobulb colour at species level can vary from green, yellowish-green yellow or reddish-brown. The leaves at species level range in shape and can be lanceolate, linear-lanceolate, narrowly elliptic, oblong-elliptic and have acute apices.
The inflorescence is usually erect but can arch. The peduncle is virtually non-existent and measures less than 1cm long. The inflorescence is heteranthus and grows from the base of a pseudobulb.
The flowers open widely and the colours vary. The sepals’ measure 5.5-6mm long, the sepals vary in shape but are usually shaped oblong-linear; the lateral sepals appear remotely falcate. The petals are slightly shorter and are a spatulate shape. The labellum is entire and narrowed at its centre. There are three keels; the two lateral keels terminate at the centre of the labellum; the median keel is much shorter. The column is curved and has a bidentate apical hood. The stelidia emerge from the base of the column and are equal to or exceed the apical hood.

Dendrochilum pallidiflavens var. pallidiflavens
Dendrochilum pallidiflavens var. oblongum
This varieties of Dendrochilum pallidiflavens can be distinguished from each other by the keels. Var oblongum has an oblong or ovate oblong shaped labellum and three keels. Var brevilabratum has 3 keels.
Dendrochilum pallidiflavens var. brevilabratum also differs from var. pallidiflavens and var. oblongum by its stelidia that are equal to or exceed the column apex and the longer sepals.
The epithet refers to the short labellum.
