The Flowers

 

The sepals and petals have not been described.

 

The flowers are greenish-amber. The labellum is shaped ligulate and has either an acute apex or a retuse apex with an apiculum in its centre. The labellum’s margin is erose basally. There are two keels that run the length of the labellum and are joined by a short ridge basally. The stelidia are shaped falcate and grow from above the base of the column and are equal to the column apex. The apical wing is shaped semi ovate and has an entire margin.

 

Culture

 

I do not think this species is in cultivation, if it is it could be a mislabelled plant of Dendrochilum simile or Dendrochilum odoratum.

Other Information

 

Reichenbach compared this species to Dendrochilum simile. The original description only contains information about the flower and any other information about the rest of the plant is unavailable in literature. Jim Comber failed to mention this species in The Orchids of Java. I have translated the description above from the original Latin of Reichenbach’s.

 

This species differs from Dendrochilum simile because Dendrochilum simile has a bidentate margin on the apical wing and a tooth on each stelidia.

 

Based on the descriptions, the only difference I can find between Dendrochilum odoratum and this species is that the stelidia are equal to the apical wing rather than almost reaching the column apex as in that species and that the apical wing’s margin is entire rather than dentate or deeply cleft as in that species. I believe that Dendrochilum odoratum is most similar to this species, particularly if looking at a specimen with a deeply cleft apical wing.

 

When describing Dendrochilum malindangense Henrik Pedersen wrote that the nearest species is this one.
