9. Annona acuminata Safford, sp. Nov. 
SMALLER WILD ANNONA OF PANAMA. 
Anona echinata Hemsl. Biol. Centr, Amer. Bot. 1: 19. 1879, not Dunal, 1817. 
A small tree 5 to 7 meters high with slender branches roughened by thickly crowded 
prominent reddish brown lenticels; very young branchlets clothed with minute 
appressed ferrugineous hairs scarcely visible even with the aid of a lens, very soon 
glabrate; leaves small, thin, membranaceous, glabrate, pellucid-punctulate (those of 
flowering branches only observed), 6.5 to 8 cm. long and 1.8 to 2.2 cm. broad, lanceolate 
or oblong-elliptical, gradually acuminate at the apex, the tip usually rounded, acute 
at the base, the blade decurrent on the short thick channeled petiole (1.5 to 3 
mm. long), often conduplicate or revolute; midrib impressed above, prominent 
beneath, ferrugineous or cinnamon brown, and bearing minute scattered appressed 
hairs when young, but at length glabrous or nearly so; lateral nerves 10 to 12 on each 
side, not impressed above, distinct beneath and colored like the midrib, glabrous, 
dichotomously branching and anastomosing before reaching the margin; peduncles 
solitary, 1-flowered, extra-axillary, sometimes nearly opposite a leaf, at first minutely 
appressed -pilose, at length glabrate, 12 to 16 mm. long, remarkable in comparison with 
closely related species for two linear-lanceolate acuminate bracteoles 2 to 4 mm. long, 
one situated at the base and one at or a little above the middle; flower subglobose in 
bud, about 15 mm. in diameter: calyx gamosepalous, subtriangular, with three slender 
acuminate points projecting from the broad base, appressed-pilose on the outside 
and with a fringe of stiff rufous hairs within at the base of the receptacle; receptacle 
convex, clothed with pale yellow hairs between the bases of the stamens; stamens 
numerous, 2.5 mm. long, the connective expanded into a broad flat hood above the 
pollen sacs, its surface muriculate with short stiff points but without hairs; pollen 
bright orange yellow, in two vertical columns of tetrads; carpels numerous, the 
minutely hirtellous ovaries united into a disk-like mass and bearing club-shaped, 
easily detached styles 1.5 mm. long; fruit not observed. (PuaTE 97 ) 
Type in the Kew Herbarium (from Herbarium Hookerianum, 1867), collected at 
the Bojfo Station, Panama Railroad, Isthmus of Panama, J une, 1861, by Sutton Hayes 
(no. 142). ‘A small tree, 15 to 20 feet high.”’

mass of ovaries denuded of their styles; c, carpels, composed of short hairy ovaries surmounted by club- 
shaped styles; d, stamens, showing linear pollen sacs, one of which has opened, displaying the pollen 
grains in tetrads, and the expanded, mutriculate connective heads. a, Natural size; b, scale about 2;

10. Annona jamaicensis Sprague. 
WILD ANNONA OF JAMAICA. 
Anona jamaicensis Sprague, Bull. Herb. Boiss, II. 5: 701. 1905. 
Anona sericea Griseb. F1. Brit. W. Ind. 5. 1864, not Dunal, 1817. 
A slender tree 3 to 9 meters high; young branchlets ferrugineous-pubescent, soon 
glabrescent; branches grayish brown or reddish brown, bearing many inconspicuous 
brownish lenticels; old leaf scars prominent, lined with ferrugineous tomentum; 
petioles 7 to 18 mm. long, channeled above, finely appressed-pubescent at first, at 
length glabrescent; blades ovate or obovate to obovate-oblong, shortly and obtusely 
acuminate at the apex and rounded or obtusely cuneate at the base, 10 to 20 cm. 
long, 4.5 to 8.5 cm. broad (those near the base of young branches often considerably 
smaller), glabrous above, finely appressed-pubescent beneath, at length sparsely so 
except along the ferrugineous midrib and lateral nerves; midrib impressed above, 
prominent beneath; lateral nerves slightly curved, 11 to 18 on each side the midrib,
