Plant of the Anyu, Tropaeolum tuberosum Ruiz and Pavon, a Peruvian 

 Mountain Root Crop. (See S. P. I. Nos. 41 185 and 41 186.) 



This rather close relative of the ordinary nasturtium of our gardens is cultivated in the plateau region 

 of Peru for its tubers, which are eaten like potatoes, ocas (Oxalis tuber osa Molina), anduhucus ( Ullucus 

 tuberosus Calder) but chiefly in the form of soups. The tubers are unusually good keepers, some 

 having reached Washington in good condition in mid-September which were collected in early April. 

 They are of at least two forms, one with short coarse purple stripes mostly near the very deep eyes, 

 and the other with larger stripes of a lighter color. (Photographed by G. B. Gilbert for the Yale- 

 National Geographic Society Peruvian Expedition, Sicuani, Peru, April 10, 1915; about one-fourth 

 natural size; P17749CA.)
