The Plants Description

 

The pseudobulbs are clustered along the rhizome and are shaped fusiform. The pseudobulbs measure 3.2-4.0cm long and 0.4-0.5cm in diameter. The pseudobulbs are covered by 2-3? cataphylls while they are growing. The cataphylls disintegrate into persistent fibres as the pseudobulbs mature. The leaves are petiolate; the petiole measures 0.8-1.5cm long. The leaf blades are shaped lanceolate and have obtuse apices. The leaf blades measure 9.0-13.7cm long and 2.0-3.4cm wide. The leaves are thin textured and have 6-7 distinct nerves.

 

The Inflorescence

 

The inflorescence is synanthous. The peduncle is erect and measures 4.3-4.5cm long. The rachis is probably nodding and measures c31.8cm long. The flowers alternate distichously and are spaced 4.0-4.5mm apart.

 

The Flowers

 

The flower colour is white. The sepals and petals spread widely. The dorsal sepal is shaped linear-lanceolate and has a subacute apex. The dorsal sepal measures c6.3mm long and c1.9mm wide. The dorsal sepal has entire margins and is 3-veined. The lateral sepals are shaped linear-lanceolate and have acute apices. The lateral sepals measure c6.5mm long and c2.0mm wide. The lateral sepals have entire margins and are 3-veined. The petals are shaped linear-oblong and have obtuse apices. The petals measure 4.6mm long and 1.5mm wide. The petals have entire margins and are 3 veined. The labellum is easily versatile, probably pendent, 3-veined and 3-lobed. The labellum measures c5.5mm long and 2.4-2.5mm wide. The side lobes spread widely are shaped obliquely linear-triangular and have acute apices. The side lobes are shorter than the mid-lobe. The mid-lobe is shaped obovate-spathulate and has a rounded apex. The margins are entire except on the upper side lobes where they are erose. There is a transverse E shaped callus at the base of the labellum; the lateral arms form keels which terminate at the middle of the column. The column is suberect, somewhat incurved and measures c4.2mm long. The column foot is short. The apical hood is prolonged into a rounded, truncate dentate wing that distinctly exceeds the anther cap. The stelidia grow outwards from the middle of the column and terminate below the apical wing. The stelidia are shaped linear and have subacute apices.

Other Information

 

The field notes on the holotype (written by Quisumbing?) name the collection as Dendrochilum sp. nov. affine clemensiae.

 

Henrik Pedersen agreed with Quisumbing's decision to group this species with Dendrochilum gracile, Dendrochilum longifolium and Dendrochilum papillosum on account of the longitudinally striated pseudobulbs, few nerved bracts and quite entire petals (Pedersen 1997).

 

The rachis is very long in comparison to the peduncle.

 

This species is only known from the type (Pedersen 1997)
