3. Geographic and altitudinal range of the species, followed by specimens ex- 

 amined in addition to the type collection. 



4. Vernacular names and sources of these names (usually specimen labels). 



5. Discussion of the species. 



The specimens have been cited geographically by country and province from 

 north to south and west to east as follows: 



COLOMBIA (Departments and Commissaries): Antioquia, Caldas, Cundina- 

 marca, Valle, Tolima, Cauca, Huila, Narino, Putumayo. 



ECUADOR (Provinces): Carchi, Imbabura, Pinchincha, Cotopaxi, Napo- 

 Pastaza, Bolivar, Tungurahua, Chimborazo, Guayas, Canar, Azuay, Santiago- 

 Zamora, El Oro, Loja. 



PERU (Departments): Piura, Cajamarca, Amazonas, La Libertad, Ancash, 

 Huanuco, Pasco, Junln, Huancavelica, Cuzco, Ayacucho, Apurlmac, Puno. 



BOLIVIA (Departments): La Paz, Cochabamba, Santa Cruz, Chuquisaca, Tarija. 



ARGENTINA (Provinces): Jujuy. 

 Only limited data for the exact locality of each collection within the province or 

 department has been cited; this data is sufficient in most cases for the location 

 of the place of collection by use of the American Geographical Society's index to 

 their map of Hispanic America (1943) and the quadrangles of this map. Obscure 

 localities in Ecuador have sometimes been found by use of Wolf's map of Ecuador 

 (1892); other localities have usually been pinpointed by use of the references in 

 the Barnhart Biographical Index of botanists in the library of the New York Bo- 

 tanical Garden. Complete names of collectors are given in the index to collections 

 at the end of this study.
