Seeds with endosperm. 3. Sideroxylon. 



Seeds without endosperm. 4. Lucuma. 



Corolla-lobes with a large median lobe and 2 smaller 

 lateral lobes. 

 Ovary glabrous : endosperm copious. 5. Dipholis. 



Ovary pubescent : endosperm wanting or scant. 6. Bumelia. 

 Corolla lobes with dorsal appendages. 7. Mimusops. 



1. CHEYSOPHYLLUM L. Shrubs or trees. Leaf-blades commonly 

 lustrous-pubescent beneath. Calyx-lobes mostly 5. Corolla, like the calyx, 

 often pubescent: lobes mostly 5, entire. Anthers emarginate and apiculate. 

 Style wanting: stigma lobed. 



1. C. olivaeforme L. Evergreen tree, becoming 10 m. tall, the twigs closely 

 pubescent : leaf -blades leathery, oblong, elliptic, or oval, 3-10 cm. long, lustrous- 

 pubescent beneath: calyx-lobes suborbicular, 1.5 mm. long: corolla white, 

 about 5 mm. wide; lobes suborbicular: berries oval, about 2 cm. long, dark- 

 purple. — All year. 



The Satikle-af grows in hammocks along the lower two-thirds of the eastern 

 coast of peninsular Florida and along the lower portion of the western coast, and 

 in the hammocks of the Everglade Keys and the Florida Keys. The brown and red- 

 tinged heart-wood is close-grained, heavy, and hard. (IF. I.) 



2. SAPOTA Mill. Trees. Leaf-blades glabrous. Calyx-lobes 6, or rarely 

 5, pubescent. Corolla glabrous: lobes 6, or rarely 5, toothed. Anthers blunt. 

 Staminodia nearly as long as the corolla-lobes. Style elongate: stigma minute. 

 Berry spheroidal or elongate, rough. 



1. S. Achras Mill. Tree with rusty-tomentose twigs: leaves and flowers ap- 

 proximately at the ends of branchlets: blades oblong to elliptic, varying to 

 broadest above or below the middle, 5-12 cm. long: pedicels rusty-tomentose, 

 about as long as the petioles: calyx-lobes 8-10 mm. long: corolla 8-10 mm. 

 long; lobes about i as long as the tube: berries ovoid or depressed, 4-8 cm. 

 in diameter. — Spr. & sum. 



The Sapodilla, a native of the West Indies, grows in hammocks in southern 

 peninsular Florida and the Keys. The red-striped wood is close-grained, heavy, and 

 hard. (IF. /.) 



3. SIDEROXYLON [Dill.] L. Shrubs or trees. Leaf -blades not lustrous- 

 pubescent. Calyx-lobes 5-6. Corolla glabrous: lobes 5-6, entire. Anthers 

 notched. Staminodia much shorter than the corolla-lobes. Style columnar: 

 stigma truncate. 



1. S. foetidissimum Jacq. Evergreen tree becoming 25 ni. tall: leaf -blades 

 thin-leathery, oblong to oval or rarely ovate, 4-1.5 cm. long, glabrous at 

 maturity: calyx-lobes suborbicular, about 2 mm. long: corolla light-yellow, 6-7
