67. SAPOTACE^E, SAPPODILLA FAMILY. 



Mainly tropical trees or shrubs, with hard wood, and in other 

 respects also resembling the last family, but mostly with milky 

 juice, perfect flowers, anthers turned outwards, erect ovules, and 

 bony-coated seeds. Represented S. by a lew species of 



1. BUMELIA. (Ancient name of a kind of Ash, transferred to this genus.) 

 Flowers small, white or whitish, in clusters in the axils of the leaves. Calyx 

 5-parted. Corolla 5-cleft, and with a pair of internal appendages between the 

 lobes, 5 good stamens before them, and as many petal-like sterile ones or 

 scales alternating. Ovary 5-celled, hairy: style' 1, pointed. Fruit cherry- 

 like, containing a single large stony-coated seed. Small trees or shrubs, with 

 branches often spiny, and deciduous but thickish leaves entire. Fl. summer : 

 fruit purple or blackish. Natives of river-banks, c. 

 B. lycioides, from Virginia to Illinois and S., is smooth, with obovate- 



oblong or lance-wedge-shaped leaves 2' -4' long, and greenish flowers. 



B. t6nax, still more southern, has smaller leaves brown-silky underneath, 



and a shorter white corolla.

woolly beneath, and white corolla. 



68. STYRACACE^E, STORAX FAMILY.

 phous stamens, only one style, and a 1 - 5-celled 1 - 5-seeded fruit. 

 Ovules as many as 2 in each cell. Calyx in ours coherent more or 

 less with the 2 - 4-celled ovary. 



* 1 STYRAX Flowers from the axils of the leaves, white, showy, on drooping pe- 

 duncles. Calyx scarcely 5-toothed, its base coherent mcrel'v with the base of 

 the 8-celled many-ovnled ovary. Corolla open bell-shaped, mostly 5-parted,

 1-reUed. with usually only one globular hard-coated sml at its base. 



2. HALESLA Flowers 'in fasciclefl on hanjring pedicels from the axils of the
