278 STORAX FAMILY. 



1. STYRAX. Flowers from the axils of the leaves, white, showy, on drooping peduncles. 



Calyx scarcely 5-toothed, its base colierjnt merely with the base of the 3-celled many- 

 ovuled ovary. Corolla open bell-shaped, mostly 5-parted, rather downy outside.

 at base, and linear anthers. Fruit dry, 1-celled, with usually only one globular hard- 

 coated seed at its base. 



2. HALESIA.. Flowers in fascicles on hanging pedicels from the axils of the deciduous 



leaves of the preceding year, white, showy. Calyx 4-toothed, the tube wholly cohe- 

 rent with the 2^-celled ovary. Petals 4, or united into a bell-shaped corolla. Sta- 

 mens 8-16 ; filaments monadelphous at the base ; anthers linear-oblong. Ovules 4 in 

 each cell. Fruit large and dry, 2^-winged, within bony or woody, and 1-4-celled, a 

 single seed filling each slender cell. 



8. 8YMPLOCOS. Flowers yellow, in the axils of the thickish leaves, not drooping. 

 Calyx 5-cleft, coherent with the lower part of the 3-celled ovary. Petals 5, broad, 

 nearly separate. Stamens very many in 5 clusters, one attached to the base of each 

 petal ; filaments very slender ; anthers very short. Fruit 1-celled, 1-seeded, small 

 and dry.
