The collector describes the flowers as white with two violet streaks 

 on the petals. 



Àppendicula (sect. Fissanthera) kinabalucnsis J. J. S. comb. nov. — 

 Chilopogon kinabaliiense Ames! Orch VI (1Q20}, 141. 



A few particulars may be added to Ames' description. 



The bracts are scattered iiot distichous as in the section Chilopofron. 

 The mentuiii is inflated at the apex, contracted at the base. The lip has 

 a broad very concave claw adnate to the coliimn foot, the epichyl is not 

 much broader, convex and possesses a longitudinal ridge. The anther is 

 rounded with a rather deeply cordate base and a gibbous connective, 

 produced at the apex into a conspicuous bifid beak narrower than the 

 anther, with the lacinia nearly parallel and acute. There are 6 clavate 

 pollinia very niuch narrowed towards the base, 2 much shorter caudiculae 

 and a single \/"Shaped glandula. The rostellum is projecting and bidentate. 



The plant belongs to the section Fissanthera. It is most nearly related 

 to A. floribiinda SCHLTR., which, however, seems to be a larger plant with 

 much longer generally branched inflorescences, the mentum hardly inflated 

 at the apex, a shorter claw to the lip and the teeth of the anther curved 

 outward. 



1 think that A. Mcnillii Ames belongs to the same affinity.
