SAFFORD—CLASSIFICATION OF ANNONA, 41 
almost strigillose-villous indument; indument of the outer petals finer, subseri- 
ceous, of a lighter chestnut brown or cinnamon color; flower buds ovate-conical 
or fusiform, acuminate at the apex and sometimes triangular-pyramidal with 
the apex more or less curved; calyx 3-parted, the lobes scarcely 4 mm. long, 
broadly ovate-triangular, acute or acuminate; petals closely united in bud, 
broadly spreading after anthesis, fleshy but thin, the outer ones united at the 
base (gamopetalous), 12 to 16 mm. long, concave at the base around the essential 
parts and narrowed into a long-acuminate apex, white within with a light red 
or purplish spot at the base; inner petals about half as long as the outer, 
ovate, acute, excavated at the base and more connivent above the essential parts 
at first, at length opening widely, white with a purplish spot at the base; torus 
raised, conoid, minutely puberulent between the bases of the stamens and bor- 
dered about the base with stiff ferrugineous hairs; stamens numerous, yellow 
(light brown or straw-colored when dry), with short 
flat filaments and the connective expanded above 
the pollen sacs into a swollen, brown, minutely 
papillose or velvety head; carpels numerous, closely 
crowded into a conoid gyncecium borne on the apex 
torus; ovaries densely pilose with ascending rufous 
or fulvous subulate hairs, linear-oblong, tipped with 
short prism-shaped styles terminating in depressed- 
capitate velvety stigmas with their surface covered 
with minute acutish papillose cells; young fruit 
ovate-conoid, rufous or fulvous-pubescent and tu- 
berculate or verrucose from the swelling of the 
carpels composing it; ripe fruit not observed, but 
in all probability similar to that of A. cherimola 
in shape and appearance. (Piate 22. Ficures 21,
