and A. rosei Safford of the island of Hispaniola, from both of which it differs 
decidedly in the character of its leaves. 
American Rollinia emarginata in their texture and venation. 
The small globose flowers are no larger than chick-peas (gar- 
banzos). In the type specimens, as described by Schlechtendal, 
more or less imperfect minute inner petals were present, but 
in the specimens examined by the present writer no inner petals 
were observed. It is quite probable, however, that they are 
sometimes present, as in Annona rosei. 
Annona globiflora was first collected the latter part of the 
18th century near the village of Espinal, in the State of Vera- 
cruz, by Mocifio, and it was described under the name Annona 
fruticosa in Mocifio & Sesse’s Flora Mexicana. This work, 
however, remained in manuscript for nearly a century, and the 
description was not published until 1894, as above cited. The 
name Annona globiflora, very appropriately applied to it by 
Schlechtendal in 18386, must therefore take precedence. Mocifio

common name “ anonita de papagayos” as “little custard apple of the parrots.”

Section Annonella. A shrub or small tree; young branches slender, minutely 
subappressed-pilose or hirtellous, at length glabrate, terete, densely plicate- 
striate when dry, grayish brown, conspicuously dotted with pale grayish lenti- 
cels; leaves with petioles 3 to 7 mm. long, variable in shape, 
a those at the base of the branchlets, as in many other Annonaceae, 
smaller and relatively broader than the succeeding ones, orbicular 
or suborbicular, rounded or emarginate at the apex, 1.5 to 3 cm. 
long by 1.5 to 2.5 cm. broad, the succeeding ones ovate to ovate- 
t elliptical, rounded or obtuse at the base and often abruptly de- 
current on the petiole, 8 to 7 cm. long by 2 to 5 cm. broad, in

beneath pale greenish gray and densely clothed with very minute

small, in pairs or solitary, on short hirtellous peduncles not 
exceeding the petioles in length, issuing from the base of the young branchlets 
and subtended by two minute triangular pilose bracteoles; flower buds sub- 
globose-triangular, often obtusely acuminate, 5 to 6 mm. in diameter; calyx 
lobes broadly triangular, soon reflexed, 1.5 mm. long, ferrugineous-hirtellous; 
petals 3, fleshy, semiorbicular-triangular, sometimes obtusely acuminate at the 
apex, 5 mm. long and about 5 mm. broad, clothed on the outside with short 
appressed rufous hairs; stamens numerous, in 8 or 4 series, 1.2 to 1.4 mm. long, 
the linear pollen sacs borne on the back of a thick, fleshy connective, this obtuse 
or rounded at the apex, but not expanding into a hoodlike cap above the pollen 
sacs; carpels numerous, forming a broadly pyramidal gynecium; ovaries
