50 ORCHIDACEM 



A. benguetensis is very closely allied to A. Prainii, a native 

 of upper Assam, but differs from it in its entire, not 3-lobed up, 

 and in its somewhat smaller flowers. The wings on the claw of 

 the lip of A. benguetensis are very similar to those of A. Prainii 

 as figured in plate 2192 of Hooker's Icones. 



Apparently parasitic on pine roots in pine forests, dry ridges,
