distinguish them. This is unnecessary, 

 however, as tubers of the chufa for pro- 

 pagation may be obtained from most 

 seedsmen. The tubers of the chufa are 

 formed at the ends of scale-covered root- 

 stocks. The plant is extremely prolific, 

 cultivated forms usually producing 100 



dried. Tubers from wild plants are 

 usually much smaller and have a greater 

 proportion of fiber. The general ap- 

 pearance of chufas and of tubers from 

 a wild sedge are well shown by figure 9. 

 Chufas are known also by the vernacu- 

 lar names, earth almonds and ground

tubers to the plant, and instances are 

 known in which more than 600 tubers 

 were produced in one season from one 

 tuber planted in the spring. 



Well-developed tubers of the culti- 

 vated variety average about three- 

 fourths of an inch in length by three- 

 eights of an inch in diameter when 



nuts, and the plant as nut grass and 

 cache-cache. 



DISTRIBUTION. 



The northern boundary of the natural 

 range of the chufa is marked by the fol- 

 lowing localities : Southern New Bruns- 

 wick, southern Ontario, northern Ne- 

 braska, New Mexico, Arizona and the
