have no culinary value. However, their habit of growth 
is favorable to the production of a long fiber; and,

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-

fpomoea 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 mamey cna 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.)
