19142 and 19143. Xanthosoma spp. Yautia. 



From Northern Colombia. Presented by Prof. H. Pittier, of the Division 

 of Botany. Received August 31, 1906. 



" Rhizomes of two undetermined varieties of yautias which were collected in 

 the Sierra Nevada de Sta. Marta, Colombia, near the Koggaba village of San 

 Andres, at about 1,200 m. above sea level. The plant is cultivated by the In- 

 dians, although not extensively, under the name of mundi, or mi-indi. The 

 Spanish people call it malanga. In the Cauca Valley that same Xanthosoma, 

 Or one very like it, is called rascadera, a very striking coincidence with the 

 Nahautl word quequeque, applied to the same plant in some parts of Central 

 America, the meaning of which is ' that which causes itching,' while rascadera 

 signifies ' that which causes one to scratch.' 



" The Koggaba Indians cultivate Xanthosoma in the garden-like fields around 

 their houses in isolated plots, mixed in with corn, cane, cotton, coffee, coca, 

 yuca (Manihot). They do not seem to use it to any extent." (Pittier.)
