ROLLINIA ORTHOPETALA. 



Rollinia orthoretala A. DC. ( S . P. I .Nos . 22512,27579,27609) 

 is one of the finest of all the custard apples. It probably 

 ranks with the o?st chirimoya. The tree grows to a moderate 

 size 30 to 40 feet) and has the habit of an Annona , with two- 

 ranked entire leaves somewhat li,ke those of A. reticulata. 

 The greenish yellow fruit is prominently tuberculate or squa- 

 mose, and about 6 inches in diameter. The seeds, which are 

 very much live those of an Annona, are surrounded by a pleas- 

 antly flavored sweet-acidulous pulp, of a custard-li;:e con- 

 sistency. The species is very closely related to Rollinia 

 mucosa of the West Indies, but is better flavored. It appears 

 to thrive in low tropical situations which may be subject to 

 periodical floods, and in such locations where the chirimoya 

 (A. cherimola Miller) of subtropical regions does not fruit 

 well, the Rollinia can be successfully grown. It is known in 

 Brazil as Arabicu. (After Safford.) From photograph by Mr. 

 Walter Fischer, i^ara, Brazil, 2/5 natural size.
