Appendicula maquiling ensis resembles most closely among Philippine 
species A, xytriophora Reichb. f. The more compact inflorescence, dif- 
ferent floral bracts, and the elongated, lanceolate leaves are differentiating 
characters. A. lucbanensis is also a nearly related species which is in 
part sufficiently characterized by the very different callus of the labellum.

Apparently a very distinct species clearly separable from all known 
representatives of the genus in the Philippines by the bilobed membra- 
nous callus on the disc of the lip, opposite the sinus of which,- near the 
apex of the lip, a papilla-like tubercle is situated.
