(figs. 63, 64, pp. 54, 55) small, often no larger than a pea, on short slender 
peduncles, either solitary or geminate; petals 3 or 6, the outer ones thick, con- 
cave, broadly ovate or suborbicular; connectives of the stamens remarkable in 
not being broadly dilated above the pollen sacs; carpels free, the ovaries pilose 
and tipped with a tapering glabrous style; fruit (fig. 35) no larger than a peach 
with the areoles indistinctly outlined, gibbous and obtuse or terminating in a 
small point. The flowers are for the most part 3-petaled, but occasionally 
one or more inner petals are present. In addition to the type species this 
section includes Annona bicolor Urban (pl. 34), of Santo Domingo, the fruit 
of which is described and figured for the first time in the present paper, and 
A. rosei Safford (pl. 85), a new species which was recently discovered by Dr. 
J. N. Rose on the south coast of the island of Santo Domingo.

Annona montana Macfad. Fl. Jam. 7. 1837. 
Section Euannona. <A tree usually of small dimensions, but sometimes reach- 
ing the height of 15 meters; leaves coriaceous, glabrous, dark green and very 
glossy as though varnished above, lighter green beneath, very similar to those 
of Annona muricata L., but larger, obovate-oblong, acute or rounded at the base 
and abruptly acuminate at the apex, usually about 12 to 18 cm. long and 
5 to 6.5 em. broad; flowers similar to those of Annona muricata, but with the 
3 outer petals obtuse or acute, rarely acuminate, normally about 4 cm. long and 
8 cm. broad, sometimes much larger (6 cm. long and 4 cm. broad), valvate, 
cordate-ovate, apparently glabrate on the outside but clothed with minute 
appressed hairs as seen under the microscope; inner petals imbricate, thin- 
edged, broadly obovate, usually rounded at the apex and narrowed at the base 
into a slender claw; calyx lobes triangular, acute, often persistent at the base 
of the fruit; peduncles thickest at the apex, glabrous, solitary or in pairs, 
extra-axillary, sometimes apparently axillary when issuing from the base of 
a new branchlet, often opposite a leaf, about twice the length of the petioles 
and bearing 2 small, sessile or semiamplexicaul, more or less persistent bract- 
lets, these ovate or orbicular in shape and acute at the apex; receptacle 
truncate-conoid or subcylindrical, 5 to 6 mm. in diameter and 4.5 to 5 mm. 
high, thickly covered with minute straight hairs; stamens very numerous, in 
18 to 20 rows, club-shaped, 4.3 to 5.5 mm. long, the two parallel pollen sacs 
2.5 to 8 mm. long and the expanded connective above them 0.5 mm, thick and 
1 mm. broad with its surface minutely muriculate; carpels forming a cluster 
(gynecium) at the apex or center of the receptacle, 5 to 5.8 mm. high, the 
styles 3 mm. long covered with chestnut-colored sericeous hairs, the stigmas 2 
to 2.8 mm. long, pale brown and velvety, broad at the end and tapering to 
the slender base, becoming glued together into a flat or convex surface by 
a viscous exudation just before the dehiscing of the pollen sacs and sepa- 
rating from the tips of the styles after pollination; fruit broadly ovate or 
subglobose, tomentose at first, at length glabrate, varying in size from that of
