ORCHIDACE^ 



This plant has several more or less close allies. It is unUke 

 Bulbophyllum maculosum Ames in color of flower, unarmed col- 

 umn and dissimilar lip. B. vinaceum is separable from B. daga- 

 mense Ames by its smaller thicker leaf, much broader dorsal 

 sepal and different lip, and from B. cornutum var. ecornutum 

 J. J. Sm. by its much larger flower which is of another color. 

 Narrower leaves and very unlike lip distinguish it from B. patens 



King.
