Type in the U. S. National Herbarium, no. 675793 and 675794, 

 collected in humid forests around Los Siguas Camp, southern 

 slope of Cerro de la Horqueta, Chiriqui, altitude about 1,700 

 meters, William R. Maxon 5415, March 17-19, 1911. 



Specimens included: Costa Rica: "Barba, borde du Rio 

 Mancaron," altitude 1,200 m., Pittier & Durand 2001. U. S. 

 National Herbarium no. 154300, without definite locality and 

 collection number, Cooper. 



In a cover with some South American plants marked tentatively 

 sp. nov. by Professor L. M. Underwood, are two sheets from 

 Colombia (altitude 5,000 feet, H. Smith 1084). One has a rhizome 

 33 cm. high, and they surely belong in this species.
