Additional Comments

 

This species is thought to have similarities to Dendrochilum gibbsiae. The holotype for this species can not be located and until it can be examined this species will continue to be considered an incompletely known taxon but separate from Dendrochilum gibbsiae.

 

Henrik Pedersen wrote in 2007 that Jeffrey Wood recommended that Dendrochilum trilobum be considered a separate species. The authors of the Orchids of Sarawak thought it likely that Dendrochilum trilobum is conspecific with Dendrochilum gibbsiae. If the type is found and confirmed this Dendrochilum trilobum’s name would have priority over Dendrochilum gibbsiae.
