Tubers of the Congo Yam. Dioscorea cayenensis Lam.. S. P. I. 



No. 54901.; 



The Congo yam, shown above greatly reduced in size, has rich yellow flesh strikingly different 

 from all other yams commonly grown. While the flavor is not so delicate as that of many other 

 yams, the texture is good and the color attractive. The average weight of tubers, when grown 

 imder favorable conditions, is 4 to .5 pounds. (Photographed bv E. L. Crandall, AVashington,
