53622 and 53623. 



From Tripoli. Libia. Africa. Seeds presented by Dr. E. O. Fenzi. Receivcl 

 .Tune 1, 1921. Quoted notes by Dr. Fenzi. 



53622. Eleusine cokacana (L.) Gaertu. Poacese. Ragi millet. 



" Bescna. The l)escna appears to be more prized for forage than for 

 grain, although the natives assure me that it will keep in perfect 

 condition for 100 years. This and gssah [S. P. I. No. 53623] are prac- 

 tically the only summer forage plants grown by the Arabs, under irri- 

 gation, of course." 



53623. Pennisettm glaucitm (L.) R. Br. Poacete. Pearl millet. 

 (P. typhoideum Rich.) 



" Gssah. The seed of the gssab has a better taste than bescna and 

 always commands a higher price on the market. It also grows taller 

 than bescna and yields more forage, but will need also much more 

 water. It is claimed that it will ripen seeds in 40 days from date of 

 sowing, which statement, however, I can not guarantee. From what I 

 know P. fflaucinn finds its northern cultural limit in Libia. 



53624. AvENA sATivA L. Poacese. Oat. 



From Aberystwith. Wales. Seeds presented by K. G. Stapledon. director.

 {L. E. Thatcher.) 



53625. RuBus macraei A. Gray. Rosaceae. Akala. 



From Honolulu, Hawaii. Seeds collecte<l by J. F. Rock, Agricultural Ex- 

 plorer of the Department of Agriculture. Received June 6, 1921. 

 " Spineless variety from near Shipman Ranch, Kilauea, Hawaii. This 

 variety grows epiphytically in the forks of large koa trees [Acacia koa Gray) 

 and on fallen logs of the same species, inaccessible to cattle. The dark-red 

 fruits attain a diameter of nearly 2 inches, are very juicy, and, though slightly 

 hitter, are quite pleasant to the taste. The variety would likely improve 

 under cultivation. The canes do not grow as straight as those of the yellow 

 and re<l varieties on Mauna Kea rs. P. T. Nos. 534«<0 to .53482), but they are 

 over an inch in diameter at the base: the whiplike branches are very scandent 

 and rambling. These seeds came from a fern forest at an altitude of 4,500 

 feet on the slopes of Mauna Loa, Hawaii, May, 1921." (Rock.)
