41185 and 41186. Tkopaeolum tubekosum Ruiz and Pavon. Tropaeola- 



cese. Anyu. 



" One of the Andean root crops, generally cultivated in the potato- 

 growing districts of the plateau region of Peru. Though apparently 

 less popular than the oca and ullucu, the anyu has one important ad- 

 vantage over all the Peruvian root crops, including the potato, in its 

 keeping qualities. Specimens collected in the district of Sicuani on 

 April 9 were kept for three months at Ollantaytambo and then brought 

 to Washington, and were still in good condition the middle of September. 

 This means that the anyu tubers would be very easy to handle com- 

 mercially in case they should prove to be of use in the United States. 

 In Peru they are eaten like potatoes, papa lisas, and ocas, chiefly in the 

 form of soups. The anyu plant is a rather close relative of another 

 Peruvian species, Tropaeolum majus, a familiar ornamental cultivated 

 in the United States under the name nasturtium. Hybrids between these 

 two species might be of interest as affording a possibility of securing 

 ornamental varieties that could be propagated from tubers. The flowers 

 of T. tuberosum are not so large as those of T. majus and do not open 

 so widely, but in other respects the general appearance is much the 

 same. Experimental plantings of anyu should, be made in the elevated 

 districts in the Southwestern States and along the Pacific coast. In 

 comparison with potatoes there appear to be very few varieties of the 

 anyu:' 



41185. "No. 2024. Ollantaytambo, Peru, June 15, 1915. Cheojche 

 ahu. Spotted anyu. Strikingly marked with purple stripes, 

 especially about the eyes. Two forms are found, one with short, 

 coarse stripes, mostly confined to the vicinity of the eyes, which 

 are very deep, with the surface very prominent between the eyes, 

 making the outline very irregular. The other form has larger 

 stripe's of a somewhat lighter color. These are called Pucacheojche; 

 the other Yanacheojche, or black striped. 



41186. "No. 2031. Ushcopata, Sicuani, Peru, April 9, 1915. Qquello 

 or yellow anyu. From Ushcopata, a few miles above Sicuani." 

 For an illustration of an anyu plant, see Plate X. 



41187. Canna edulis Ker-Gawler. Cannacese. Canna. 

 " No. 1674. Santa Ana, Peru, July 6, 1915. Achria. Canna cultivated 



at Santa Ana, entirely different from that below San Miguel. Tubers 

 are superficial and green, flowers scarlet and of different form. Midribs 

 of leaves dissolve into fine veins some distance below the apex. Plant 

 looks like ordinary canna, familiar in the United States. Roots white 

 where not green. Inflorescence joints come apart. Flowers not in good 

 condition." 



41188. Polymnia sonchifolia Poepp. and Endl. Asteraceae. 



"No. 2022. Ollantayambo, Peru, July 24, 1915. Llacono. A root crop 

 grown sparingly about Ollantaytambo at altitudes of about 10,000 feet. 

 The tubers resemble sweet potatoes externally, but are white and 

 watery within and taste much like Jerusalem artichokes."
