SAFFORD—ANNONA SERICEA AND ITS ALLIES. 275 
not impressed above, prominent and sharply defined beneath; peduncle 8 to 12 mm. 
long, ferrugineous-tomentose, with a small tomentose bracteole near the middle; 
flowers ovoid to oblong in bud, 3-petaled; calyx 3-parted, the lobes broadly ovate, 
obtuse or obtusely acuminate, 3 mm. long and 3 mm. broad at the base, clothed on 
the outside with ferrugineous tomentum like that of the peduncle; petals ovate to 
oblong, obtuse, 11 to 20 mm. long and 6 to 8 mm. broad, thick and leathery, clothed 
on the outside with fine ferrugineous velvety tomentum, lined within except near 
the reddish brown base with fine grayish tomentulum; stamens numerous, 1.6 to 2 
mm. long, the connective somewhat broader than the lobes of the whitish pollen 
sacs, minutely papillose (under the microscope); carpels numerous, closely crowded 
in a conoid gyneecium, the styles together with the ovaries about 1.25 mm. long, the 
latter clothed with ferrugineous sericeous hairs; stigmas compressed-ovoid, 0.5 mm. 
long, cemented together at the time of pollination by a reddish brown viscous fluid; 
fruit globose or somewhat oblate, more or less umbilicate at the base, 4 to 6 cm. in 
diameter, clothed with grayish brown pubescence, with the carpels produced into 
tubercles usually hooked or incurved at the tips; seeds 12 to 16 mm. long, 6 to 10 mm. 
broad, obovate, somewhat compressed, reddish brown or tan-colored, with a smooth 
thin testa more or less wrinkled by the inclosed ruminate albumen. (PLATEs 98, 99.) 
Type in the Kew Herbarium, collected near Bath, eastern Jamaica, by William 
Purdie, 1844, Cotypes, without definite locality, collected by March (nos. 4, 7, 1571) 
and Alexander Prior (also cited by Grisebach under ‘‘A. sericea”). 
Distrrsution: Known only from the island of Jamaica. 
SPECIMENS EXAMINED: JAMAIcCA—Without definite locality, 1849-50, Alexander 
Prior, in Gray Herbarium (with ovoid flower bud); roadside near Hampton, Santa 
Cruz Mountains, alt. 700 meters, September 4, 5, 1907, N. L. Britton 1196, in herb. 
New York Botanical Garden (with almost mature fruit); Sheldon Road, St. Andrew, 
alt. 750 meters, September 10, 1897, William Harris, 6861, in U. 8. National Herba- 
rium (with fully developed flower and fruit). 
Annona jamaicensis has been known hitherto from specimens in which the flowers 
were evidently immature. The petals were described by Sprague as ovate, obtuse, 
11 to 12 mm. long and 8 mm. broad. The accompanying drawing (pl. 99) shows 
them to be longer and relatively narrower when fully developed, approaching the 
shape of the petals of A. cherimola and its allies, but distinguished from them in not 
being triquetrous or keeled on the inner face. Moreover, the connective of the sta- 
mens is not so much swollen as in the section to which those species belong; and 
the incurved tips of the mature carpels serve also to prevent the confusion of this 
species with A. cherimola Mill., which is sometimes cultivated in the mountains of 
Jamaica. The flower buds somewhat resemble those of A. sericea when immature, 
but the indument of the petals in the present species is more velvety and of a more 
reddish color, while the stamens never bear hairs on the connective terminal. In 
addition to these points of difference the leaves are relatively broader and are never 
clothed with the dark red, soft, velvety lining of the leaves of A. sericea and its 
close allies.
