A rapid-growing tree ; very ornamental, from its compound leaves, and the 

 fine pea-green of its young shoots; arriving at maturity in 15 20 years. 

 American seeds, which ought to be sown as soon as possible, or layers, in any 

 common soil. 



Other Species o/Negundo. A" californicum Tor. $ Gray, found by Douglas,

OKD. CHAR. Calyx campanulate, 5-lobed. Ovary roundish, trigonal. Seeds 

 large and globose ; albumen wanting. Embryo curved, inverted ; with 

 fleshy, thick, gibbous cotyledons, not produced above ground in germination. 

 Plumule large, 2-leaved. Deciduous trees, natives of North America and 

 Asia. 



Leaves compound, opposite, exstipulate, deciduous ; leaflets 5 7, ser- 

 rated. Flowers terminal, in racemes, somewhat panicled. All the known 

 plants of this order cross-fecundate freely, and by most botanists they are 

 included in one genus ; but so numerous are the garden varieties, that we 

 have thought it more convenient to follow those authors who separate the 

 species into two genera. These are ^'sculus and Pavirt, which are thus 

 contradistinguished :
