Prof. Reichenbach rightly compares ihis for appearance lo 0. falcipetalum. It is 

 distinguished by tlie two sniall triangular wings being stationed ut the hase of ibe 

 stigma . and by the crest, which consists of a few iriangular keels poiniing forwards, 

 and soiue sinuous roundish waris sianding on either side between it and ihe lower 

 edgc of the lip. I do iio not flnd, ihat ihc lip is retuse and iridenlate as described 

 by Rclib., whu sceius lo have examiacd an injured speciuien.
