Bumelia. SAPOTACE^. 67 



extrorse, versatile : frnit cherry-like, with thin pulp, containing a mostly solitary erect 

 seed (from a 5-ovuled ovary) ; the scar small and basilar or nearly so. 



3. DIPHOLIS. Petaloid staminodia mostly erosely or iimbriately toothed. Seed with 

 copious albumen ; the embryo in its axis with flat cotyledons. 



4. BUMELIA. Petaloid staminodia entire or denticulate. Seed destitute of albumen ; 

 the cotyledons very thick and fleshy, commonly consolidated. 



* * Calyx double, of 6 or 8 sepals in two series ; the outer almost valvate and enclosing 

 the inner and thinner. 



5. MIMUSOPS. Corolla of or more exterior proper lobes, and twice as many similar 

 appendages, a pair in each sinus outside of a thin scale-like or petaloid staminodium. 

 Anthers sagittate, extrorse. Ovary G-8-celled. Fruit baccate, maturing one or few seeds. 



1. CHRYSOPHYLLUM, L. Star-apple. (Formed of /pi;^'6s% gold, 

 and cpvXXov, leaf, from the golden sheen of the lower face of the leaves.) — Hand- 

 some trees of tropical regions ; with the leaves in the commoner species green 

 and glabrous above, and beneath resplendent with a golden or copper-colored 

 silky pubescence, traversed by fine and close parallel transverse veins : flowers 

 small in axillary fascicles : fruit fleshy and commonly edible. 



C. Cainito, L., the common Star-apple of the W. Indies, if spontaneous in Florida, is 

 doubtless an introduced tree. It has an 8-10-crenate stigma and an 8-10-celled large and 

 globose edible fruit, as large as an apple ; the foliage undistinguishable from the following. 



C. oliviforme, Lam. Small tree: leaves oval; the lower face (also young shoots, 

 pedicels, and calyx) silky-tomentose and shining with the copper-colored or golden pubes- 

 cence : corolla white ; its tube seldom exceeding the calyx ; stigma 5-crenate : fruit ovoid- 

 oblong, 1-seeded, blackish when ripe, insipid. — Diet. i. 552; Descourt. Fl. Ant. ii. t. 71 ;

2. SIDEROXYLON, L. (Composed of oidijoog, iron, and ^vXov, wood, 

 from the hardness of the latter.) — A wide-spread tropical genus, of which a 

 single W. Indian species has reached Florida. 



S. mastichodendron, Jacq. (Mastic-tree.) Rather large tree, glabrous : leaves 

 thinnish, oval, with undulate margins, rounded or bluntish at apex, acutish at base, shining 

 above (2 to 4 inches long), on slender (inch long) petioles : flowers crowded in lateral or 

 axillary fascicles much shorter tlian the petioles : calyx barely puberulent, half the length 

 of the 5-parted yellow corolla : staminodia lanceolate, with a subulate tip, nearly entire : 

 ovary glabrous, 5-celled : fruit plum-like, 1-seeded, "yellow," — Coll. ii. t. 17, f. 5 (Catesb.

3. DiPHOLIS, A. DC. (Formed of 5<V, double, and cpollg, scale, from the 

 pair of appendages in the sinuses of the corolla.) — Three W. Indian species, 

 with the aspect and seeds of Sideroxylon, one of them extending to Southern 

 Florida. 



D. salicifolia, A. DC. Tree 60 feet high : leaves oblong-lanceolate, acuminate, gla- 

 brous, tapering into a petiole : flowers in axillary fascicles : short pedicels and calyx rusty 

 silky-pubescent : staminodia oval, erose-toothed, as long as the linear or subulate exterior 

 appendages : anthers oblong : fruit the size of a pea. — Prodr. 1. c. 188, & Deless. Ic. v. 40

 ingly transferred to this genus.) — Shrubs or small trees (of Atlantic U. S. and
