of wheat from the Calvlnla Division of the Cape Province . 

 These wheats are grown under Irrigation in soil which 

 contains a good deal of both sodium carbonate and sodium 

 chloride. They may have developed local peculiarities 

 quite different from anypossessed byAmerlcan wheats."

Tropaeolum tuberosum (Tropaeolaceae), 41185 & 41186. 

 Anyu. From Peru. Collected by Mr. 0. P. Cook on his 

 1915 South American trip. "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 im- 

 portant advantage over all the Peruvian root-crops , in- 

 cluding 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 

 back to Washington, and were still in good condition 

 the middle of September. This means that the anyu tubers 

 would be very easy to handle commercially 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, T. 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 propa- 

 gated 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 they are much the same. Experi- 

 mental plantings of anyus should be made in the ele- 

 vated districts in the southwestern states, and along 

 the Pacific Coast. In comparison with potatoes, there 

 appear to be very few varieties of anyus." (Cook.)
