calyces of the two forms belonging to the altissima, they 

 have no culinary value. However, their habit of growth 

 is favorable to the production of a long fiber; and, 

 according to Mr. M. M. Saleeby, chief of the fiber di- 

 vision of this Bureau, the two forms of this variety 

 are far superior to jute and to all other varieties 

 of roselle (including four from India) in habit, 

 growth, and yield. As yet, the problem of utilization 

 of the fiber of the altissima has not been carefully 

 studied, but it is apparently suitable for all uses 

 for which jute fiber is now employed." (Wester, Philip-

Ipomoea batatas (Convolvulaceae) , 47432 & 47433. 

 Sweetpotato. From Mayaguez , Porto Rico. Tubers presented 

 by Mr. T. B. McClelland, horticulturist, Porto Rico 

 Agricultural Experiment Station. "Tubers of two va- 

 rieties of the mamey type of sweet potato from the 

 eastern part of the island. The donor distinguishes 

 these as mameyona or 'large mamey' and mameyita or 'small 

 mamey. ' He prefers the mameyita, if it is eaten immedi- 

 ately after digging, but says that the mameyona, if kept 

 for a week, has the better flavor. However that may 

 be, both belong to the best type of Porto Rican [sweet] 

 potato." (McClelland.)
