380 SAFFORD : CLASSIFICATION OF ROLLINIA 



field photographs of the fruit, and descriptive notes. In a letter dated 

 September 12, 1912, Mr. Jimenez describes the plant as follows: 



"At Nuestro Amo it is known as anonillo. The fruits are squamose 

 and are sometimes 10 cm. by 6 cm. when mature. The skin is then yel- 

 low; but while still immature it is of a greenish and somewhat glaucous 

 color. It is edible, with an acidulous pulp and a great quantity of 

 seeds which have a tendency to adhere to the skin when the latter is 

 removed. This fruit is little appreciated by the natives, but when it 

 is kept for some time among the leaves and allowed to become fully 

 ripe, it is rather appetizing. The trees reach a height of 8 meters. 

 On young [vegetative] branches the leaves are often quite large, and 

 of a beautiful green color. I hope to obtain for you fruits fully ripe, 

 but I shall have to send them to you in fragments as I have no facility 

 for sending them entire." 



In another communication Mr. Jimenez states that all the Rollinia 

 material from Nuestro Amo was obtained from the same tree, and 

 that the specimens of fruits photographed in the field, so remarkably 

 like those of Annona squamosa, were the same as the dried fruit for- 

 warded to the writer, with the individual carpels much more distinctly 

 separated and terminating in many cases in a sharp point. 



GROUP C 



COROLLA LOBES LINEAR-OBLONG OR SPATULATE, ASCENDING OR ERECT 



AND INCURVED 



Rollinia orthopetala A. DC. Mem. Soc. Phys. Geneve, 5: 200. 1832. 



A shrub or small tree resembling R. Sieberi. Branches and leaves 

 very much as in that species; petioles slightly longer; leaf blades oval- 

 oblong, acute at each end, pilose. Peduncles in pairs; calyx lobes 

 smaller than in R. Sieberi; corolla wings erect and incurved. 



Type in Herb. De Candolle, collected near Demerara, British Guiana, 

 in 1824, by Charles S. Parker. 



Martius, in his Flora Brasiliensis, gives an amended description 

 of this species, the fruit of which he describes as "the size of an in- 

 fant's head," with sweet, white, fleshy pulp. It is not certain, however, 

 that the trees producing the fruits described by him really belong to 

 this, species. It is probably owing to Martius's description that the 

 name R. orthopetala has been incorrectly applied to several species 

 of Rollinia with large edible fruit. Of these the principal species, 

 from an economic point of view, is R. deliciosa, described above, which 

 is readily distinguished from R. orthopetala by its widely spreading, 

 decurved corolla wings.
