 Corolla hypogynous when the calyx is free : the stamens adherent to its 

 base. Ovules 2 or move in each cell. — A small family, mostly of warm 

 countries, comprising two very distinct groups or tribes. 



Tribe I. STYRACEJE. Calyx 4 -8-toothed or entire. Stamens 2 - 4 times as many as 

 the petals: anthers linear or oblong, adnate, introrse. Ovules or part of them ascend-

1. STYBAX, Tourn. Storax. 



Calyx truncate, somewhat 5-toothed, the base (in our species) coherent with 

 the base of the 3-celled many-ovuled ovary. Corolla 5-partcd (rarely 4-8- 

 parted), large ; the lobes mostly soft-downy, various in the bud. Stamens twice 

 as many as the lobes of the corolla : filaments flat, united at the base into a short
