This species has no near allies in the Philippines. The 
peculiar structure of the leaves and the shape and size of 
the perianth segments render it an easily distinguished 
and distinctive species. 
Dendrochilum yuccaefolium seems to be most nearly 
allied to D. simile Blume, a species not yet known from 
the Philippine Islands. From this species, our plant may 
be distinguished by its very different leaves and by the 
inflorescence, as well as by differences to be found in the 
flower.
