A specimen referable to this variety was placed under P. ama- 

 bilis Bl. in my first list of Philippine Orchids, published in fascicle 

 1 of this work. P. Aphrodite and P. amabilis have always been 

 more or less confused, the differences between them being very 

 slight and often obscure. In my herbarium an almost complete 

 series can be arranged which shows the gradual passage of one set 

 of characters regarded as specific into the other. The retuse apex 

 of the arms of the callus is about the only character which may 

 be relied upon to separate the Javan from the Philippine plants.
