SAFFORD—CLASSIFICATION OF ANNONA. 65 
smooth, areolate, composed of many carpels fused together in a solid mass; 
seeds small, surounded by edible pulp. 
Type species, Fusaea longifolia (Aubl.) Safford. 
The distinctive characters of the 
type of this genus were first noted by 
Baillon, who pointed out that its fruit 
(fig. 74), instead of being composed 
(as in Duguetia of distinct woody 
ecarpels, inserted in cavities in the 
hardened torus, is a solid mass, “une 
véritable boule de bois, sans asperités 
de la surface rappelant la presence 
de ses nombreux carpelles;” and that 
the outer stamens are modified into 
“lamelles pétaloides, imbriquées, 
longuement obovées;”* and Robert BH. 
Fries, who followed Baillon in regard- 
ing Fusaea as the section of a genus 
(Aberemoa), says that “this section 
departs in so many respects from the j.,, 72__mower of Fueaea longifolia. Show- 
remaining ones, that it should perhaps ing petaloid outer stamens. Reproduced 
be regarded as a special genus,” and from Baillon. 
that in its fruit it bears a great re- 
semblance to the genus Annona. The synonomy, which the elevation of this 
section to generic rank entails, and a brief description are as follows: 
Fusaea longifolia (Aubl.) Safford. 
Annona longifolia Aubl. Pl. Guian. 1: 615. pl. 248. 1775. 
Duguetia longifolia Baill, Adansonia 8: 827. 1868. 
Aberemoa longifolia Baill. Hist, Pl. 1: 205. f. 2338-235. 1868. 
A tree or shrub ; leaves very short-petioled, 
oblong-lanceolate (25 cm. long and 8 em. 
broad), obtuse or shortly tapering at the 
base, long-acuminate at the apex, above 
smooth, with midrib and nerves impressed, 
below the latter very prominent, sparsely 
hairy; flowers extra-axillary, long-pedun- 
cled, solitary or in pairs; peduncles bearing 
one or two bracteoles; calyx gamosepalous, 
deeply 3-lobed, the lobes ovate-acute, ferru- 
gineous-hirtellous on the outside; corolla 
broad, widely spreading; petals 6, in 2 rows, 
purplish, imbricate, sericeous-pilose, ovate- 
spathulate or oblong with the apices ob- 
tusely cuneate, the inner somewhat longer 
and narrower than the outer; stamens nu- 
merous, the outer sterile, petaloid, imbri- 
cated, the inner perfect, with the tips of the 
connectives expanded above the pollen sacs 
as in the typical Annonas; fruit about the 
size of an orange, globose, smooth, areolate 
but without protuberances; seeds small surrounded by a red edible pleasantly 
flavored pulp. (Ficures 73, 74.).
