raant until the second year. The 

 kinds are budded in late summer or grafted in spring 

 on the seedlings of any of the common species. About 

 40 species in the temperate region of the northern hemi- 

 sphere south to Cuba; about 15 of the species grow in 

 N. Amer. and nearly as many in E. Asia. Trees or 

 shrubs, with odd-pinnate, rarely simple, opposite Ivs. 

 without stipules : fls. in panicles, dicecious or polyga- 

 mous, with or without calyx or with calyx and a 2-6- 

 parted corolla with generally linear segments; stamens 

 generally 2 : ovary 2-celled : fr. a 1-seeded, winged
