The Plants Description
The pseudobulbs are spaced 1.2cm apart along the rhizome, shaped nearly cylindrical and are narrowed near their apices. The pseudobulbs measure 3-4cm long and 6mm in diameter. The leaves are petiolate; the petiole measures 1cm long. The leaf blades are shaped lanceolate, elliptic and distinctly narrow 6mm below the apices. The leaf blades measure 10-16cm long and 1.75-2.5cm wide.
National Herbarium Netherlands (L)
Specimen L0058496 (photo)
I could find no record.
The specimen at Leiden was collected in the wild during May.
The inflorescence is synanthous. The peduncle measures 7.5cm long and the rachis measures 6.75-15cm long. The flowers are spaced 6mm apart.
The flowers are large and green. The dorsal sepal is shaped lanceolate and has an acuminate apex. The dorsal sepal measures 1cm long and 3.5mm wide. The lateral sepals are shaped obliquely lanceolate and have long acuminate apices. The lateral sepals measure 1cm long and 3.5mm wide. The petals are shaped obliquely elliptic-oblong and have acuminate apices. The petals measure 7.5mm long and 3.8mm wide. The labellum is 3-lobed, recurved above the base and near the apex. The side lobes are short; the mid-lobe is shaped broadly ovate-triangular and is narrower basally. The labellum measures 7.25mm long, the side lobes are 4.2mm wide and the mid-lobe is 4.75mm wide. The margins on the labellum are erose. The labellum has two calli located between the side lobes and near their bases. The column is short, its apical hood is truncate and rounded. There are no stelidia on the column.
I do not think this species is in cultivation
J.J Smith considered this species to be close to Dendrochilum glossorhynchum but said it differed by having larger flowers, broadly ovate shaped bracts, and the erose and wider labellum.
