STYRACACEAE 



The Storax Family 



The storax family consists of trees or shrubs with alternate 

 leaves more or less covered with stellate pubescence, without 

 stipules and with regular, perfect flowers borne in clusters. The 

 calyx is adherent to the ovary to some extent and consists of 

 4 to 8 parts, and the corolla has 4 to 8 lobes. The stamens are 

 generally twice as many as the petals and inserted on the tube. 

 The ovary consists of 2 to 5 cells and develops into a berry-like 

 fruit or drupe, which is nearly dry, is 1-seeded and in some 

 cases is winged.
