ORCHIDACEiE 



Appendicula malindangensis (Ames) Schltr. closely resem- 

 bles this plant vegetatively, but A. longirostrata has somewhat 

 smaller leaves, much less numerous racemes, differently formed 

 lip and white instead of dark blue flowers. A close match super- 

 ficially is the Philippine A. Wenzelii Ames, but the Bornean 

 species has much larger flowers of dissimilar form. A. micrantha 

 Lindl. has smaller, more spreading leaves and much smaller 

 flowers than this species.
