quantities in the southern states, and is also offered for 

 sale in the markets of the north. Larger trees will be 

 found along the driveway east of the museum. 



Farther down the hill, west of the persimmon group, 

 is a collection of the flowering dogwood, Cynoxylon floridum, 

 both the form with white flower bracts and that with red; 

 the former being common in the woodlands. Another 

 representative of the dogwood family is the sour gum 

 (Nyssa), of eastern North America; it occurs wild in the 

 Garden in many fine specimens. 



Beyond the ginseng family, on the western slope of the 

 hill, is the olive family, represented by many species of the 

 ash (Fraxi?ius), some of which are useful for timber. The 

 common European ash is to be seen, and among the North 

 American representatives are the green ash; the Texas 

 ash, restricted to that state; the Biltmore ash, from Penn- 

 sylvania to Georgia; the white ash, and the red ash are 

 common. Following to the north is the figwort family, 

 represented by Paulownia, a native of Central China. Ter- 

 minating the sequence is the trumpet-creeper family, 

 represented by species of Catalpa; among these is the 

 Indian bean, a native of woods in the Gulf States, and 

 Kaempfer's catalpa, from China. 



Salicetum 



The area occupied by the willow plantation is between 

 the main driveway and the Bronx River, north of the 

 fruticetum, and comprises several acres. Here are brought 

 together moisture-loving willows (Salix) and poplars 

 (Populus) as a collection apart, many species grown here 

 not being represented in the arboretum and fruticetum. 

 In the corner of the salicetum, next to the driveway, is a 

 group of willows, consisting, in part, of the red-stemmed 

 willow, of horticultural origin, and the slender purple 

 willow. To the east of this may be found the golden or 

 yellow willow, of common occurrence in eastern North 

 America, but a native of Europe and Asia, and the Bashford
