FAMILY 2. SAPOTACEAE Reichenb. SApopILLA FAMILY. 
Shrubs or trees, sometimes thorn-armed, usually possessing a milky sap. 
Leaves mostly alternate, without stipules: blades entire, commonly densely 
nerved. Inflorescence clustered. Flowers perfect or rarely polygamous, com- 
plete. Calyx of 4-12 sepals, imbricated in one or two series. Corolla often 
white, with 4—several lobes, deciduous, with or without appendages at the sinuses.

corolla-tube, often to the bases of the lobes and opposite them, alternating with 
commonly conspicuous staminodia. Filaments distinct. Anthers often attached 
at the base, opening somewhat extrorsely. Gynoecium of several united carpels.
