Ash 



^55 



Of the eight American species, several resemble each other so closely 

 that a distinction is difficult, even to nurserymen, and practically, ex- 

 cept as to size, unnecessary from the ornamental point of view. The 

 two most distinct species are: 



Fig. 85. — Flowering Ash. Fraxinus Onius Linn. 



F. Americana Linn. (105), White Ash, of eastern distribution from 

 north to south, the largest, most typical of the genus, and the best in form. 



F. nigra Marsh. (106) {sambucifolia), Black Ash, a rather rare tree 

 of the sn'amp, with a darker, denser foliage of slenderer leaves, and a 

 dark gloomy aspect of stem and branches. 



F. lanceolata Borck. (107) (viridis). Green Ash, of more western 

 distribution, a smaller tree, is often mistaken for white ash and mixed 

 with it in nurseries.
