SAFFORD—CLASSIFICATION OF ANNONA, 45 
LocaL NAME; Anonilla, or “dwarf anona” (Acapulco), 
This species has very much the same habit of growth as A. globifiora Schlecht., 
the dwarf anona of eastern Mexico, but the head of the connective is broader 
than the two pollen sacs and the long, solitary peduncle is very different from 
that of A. globifiora. On account of the broad connective and the perfectly 
formed inner petals, the writer provisionally assigns A. palmeri to the section 
Atta, which includes A. sguamosa and its allies. It has, however, the habit of 
certain species of Rollinia, and its short, round-pointed, thick petals, together 
with its Rollinia-like seeds may 
indicate that it is a link between 
the genera Annona and Rollinia.

Section Atta. A shrub 3 to 10 
feet high, the young branches, pe- 
duncles, and petioles densely soft- 
pubescent; leaves elliptical to 
ovate or obovate-elliptical, usually 
rounded but sometimes acute at 
the base, rounded or obtuse and 
often minutely apiculate or mucro-: 
nulate at the apex, bright green G 
abeve, glaucous green beneath 
(when dry), 5 to 14 ecm. long by 
3.5 to 8 cm. broad, densely and ABB, 
softly pubescent when fresh, at i 
length becoming nearly glabrous 
above and glabrescent or sparsely

Fig. 54.—Flower of Annona palmeri. a, Stamens; 
b, carpel. From type specimen, Flower, scale 4; 
pubescent beneath except on the gp, scale 13, y , 
midrib and lateral nerves; flowers 
resembling those of A. cherimola but larger, short-peduncled, pubescent, 
densely so at the base; calyx divisions deltoid-ovate, 5 mm. long, clothed 
on the outside with fine long soft hairs; outer petals linear-oblong or 
oblong-lanceolate, 4 to 5 cm. long and 7 to 9 cm. broad, coriaceous, swollen at 
the base and concave about the essential parts, whitish or cream-colored with a 
dark purple or blackish spot at the base; inner petals minute (sometimes want- 
ing), finely pubescent, ovate, obtuse, 2 to 3 mm. long; torus hemispherical, 
clothed with fine straight hairs between the filaments; stamens 2.2 to 2.7 mm. 
long, with the connective terminating in an expanded cap above the parallel 
pollen sacs, its surface finely granular; carpels 2.5 to 3 mm. long, the ovaries 
1.5 to 2 mm. long, covered with rufous ascending hairs, the styles 1 to 1.5 mm. 
long, minutely puberulent (under the microscope), the stigmatic extremity 
tapering to a point; fruit conoid or globose-ovate, its surface either reticulated 
with flat areoles or bearing protuberances like those on certain forms of the 
fruit of Annona cherimola L.; seeds coffee-colored, obovoid, cuneate, truncate 
or obpyramidal, about 15 mm. long and 10 mm. broad, with a smooth thick
