 countries, comprising two very distinct groups or tribes. 



TRIBE I. ST YR ACE-flE. Calyx 4 - 8-toothed or entire. Stamens 2-4 times as many as

1. STY RAX, Tourn. STOKAX. 



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

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

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

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

 tube : anthers linear, adnate. Fruit globular, its base surrounded by the per-

 erect, with a hard coat. Shrubs or small trees, with commonly deciduous
