ORCHIDACE.E 



duo, complanati, unus prope basim lobi lateralis utriusque. Co- 

 lumna minuta, rostellum prominens. 



Dendrochilum binuangense at first glance resembles D. mi- 

 crochilum (Schltr.) Ames so closely that it might readily be mis- 

 taken for it. The floral bracts are acuminate and end in a sharp 

 triangular point, and the lateral lobes of the labellum are con- 

 spicuously longer than the middle lobe, exceeding the column 

 when erect. In Z). microchilum, on the other hand, the floral bracts 

 are obtuse and the lateral lobes of the labellum are not much 

 longer than the middle lobe.

Dendrochilum (§ Acoridium) cinnabarinum Ffitz. in Engl. 

 Pflanzenreich IV, 50. II. B. 7 (1907) 104. 



This very distinct species, of which a detailed account was 



given in Orchidaceae 3 (1908) 10, t. 27, was originally reported 



from Benguet Province, Luzon, without precise data. Since its 



discovery by A. Loher it has been collected several times, but 



always on JNIount Pulog, and would seem to be restricted in its 



distribution.
