Barbados Red, a Good Variety of Tropical Yam. (Dioscorea alata L.; 



S. P. I. No. 5556 1.) 



This is a horticultural form of Dioscorca alata, technically known as the greater yam. It is widely 

 grown in the West Indies and is closely related to the Dago hava, or Guam vain. It is, however, 

 better than the latter in some respects. The tuber has a purple inner skin, and the firm flesh, 

 mealy when cooked, is purplish and of good flavor. The yam replaces the potato in certain 

 tropical regions and in its best varieties is fully equal to the latter: indeed, good varus properly 

 cooked can hardly be distinguished from potatoes. (Photographed, natural s'ize, by E. L".
