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 any possessed by American wheats."

Tropaeolum tuberosum (Tropaeolaceae ), 41185 & 41186. 
Anyu. From Peru. Collected by Mr. 0. F. 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 Slcuani 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 llsas , 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.)
