The Plants Description

 

The pseudobulbs cluster and are shaped oblong-ovoid. The pseudobulbs measure 2.3cm long. The leaves are petiolate; the petiole measures 2.7-3.2cm long. The leaf blades are shaped lanceolate, are narrowed distally and have acute to acuminate apices. The leaf blades measure 7.4-7.8cm long and 1.5-1.6cm wide. The leaves are thin-textured and have five distinct nerves.

 

The Inflorescence

 

The inflorescence is synanthous and appears with the new growth and before the leaf has matured. The peduncle is longer than the leaves, suberect and measures 9.5cm long. The rachis is arching and measures 11cm long. The flowers alternate distichously and are spaced 0.4-0.5mm apart. J.J. Smith’s drawing showed the flowers opening from the proximal section of the rachis and with one appressed non floriferous bract.

 

The Flowers

 

Approximately 21 flowers grow on an inflorescence (Smith 1945). The dorsal sepal is shaped narrowly oblong and has a subacute and recurved apex. The dorsal sepal measures 5.0mm long and 1.0mm wide. The dorsal sepal is three veined and has an entire margin, its apex is hooded. The lateral sepals are oblique, shaped ovate-oblong and have acute or acuminate apices. The lateral sepals measure 5.0mm long and 1.75mm wide. The lateral sepals are three veined and have entire margins. The petals are shaped subobovate-oblong and have obtuse apices. The petals are narrowed basally and narrowed towards their apices (elliptic?). The petals measure 4.5mm long and 1.75mm wide, (across the middle). The petals are 2-3 veined and have entire margins. The labellum is porrect and entire. The labellum measures 4.5mm long and 1.75mm wide. The labellum is three veined and has entire margins. The labellum is shaped broadly ovate and has an obtuse and minutely apiculate apex. There is a small elevated, horseshoe shaped callus at the base of the hypochile. The column is suberect and measures 3.4mm long. The apical wing is prolonged into a truncate apex and has a lacinulate margin. The stelidia grow upwards from the top of the column on the apical hood.

Other Information

 

J.J. Smith wrote that this species differs from Dendrochilum muriculatum by its far less conspicuous muriculate inflorescence, smaller flowers, hooded apex on the dorsal sepal, wider labellum, lacinulate margins of the apical hood.

 

The epithet refers the collector of this plant, C. Monod de Froideville.
