Anrtona sp. (Annonaceae) , 54682 . From Caracas, Ven- 
ezuela. Seeds presented by Mr. H. Plttier. "Seeds of 
the so-called ' chlrimorlfton. ' The fruit is small for 
its kind, about 12 centimeters (5 in.) long, ovoid- 
oblique, and almost pointed at the apex. At the base, 
the scales are very numerous, imbricate, and mostly 
small; towards the apex they are much larger, and scat- 
tered In the shape of rounded protuberances. It is by 
far the most delicious of the sweetsops, the flberless 
flesh having just the consistence of thlckish cream and 
a delightful flavor suggestive of strawberry Ice cream 
without any of the 'gout de pommade' of either Annona 
reticulata or A . eherimola. The seeds seem to be very few 
In each fruit." (Plttier.) 
"Probably tropical in its requirements, and in the 
United States suited for cultivation only In southern 
Florida." (Wilson Popenoe.) . 
Cymbopogon rufus (Poaceae), 54679. From Lavras, 
Minas Geraes .Brazil . Seeds presented by Mr. B.H* Hun- 
nicutt. "'Jaragua grass.' A perennial grass native to 
Brazil and cultivated there and at various other places 
in the American Tropics. This leafy bunch-grass, the 
tussocks of which become a foot or so in diameter and 
the numerous leafy culms 6 to 10 feet high, is prima- 
rily a hay-grass and yields the best quality If cut 
when 3 feet high, so that from 2 to 6 cuttings may be 
made in a year. The hay is considered excellent for 
fattening and particularly desirable as horse-feed. 
Previous introductions have been tested in the South 
and in California with promising results, though the 
grass Is killed at temperatures of about 25° F. In 
Brazil the grass is also grazed, but It must not be 
overgrazed asunder such treatment it is killed. At the 
present time It is being extensively tested in Florida 
and Texas." (C. V. Piper.)
