In the description and floral analysis (in Xen. Orch. 
l.c.) it is indicated that the flower of this species has two 
pollinia, whereas a flower trom J. ’. Macbride 3774 shows 
four pollinia (one pair of Jarge pollinia and one pair of 
small ones in front of the larger). 
This genus, which is at present monotypic, was found 
by Warscewicz at Loxa in Ecuador at about 9000 feet 
altitude. In addition, we now have it from Peru ( Yanano, 
about 6000 feet altitude, J. /”. Machride 3774 and Valle 
de Santa Ana, Prov. de la Convencién, /’. L. Herrera 
8007) and from Venezuela (‘Tabay, Mérida, at about 
5400-6600 feet altitude, Gehriger 451).
