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 (Fraxinus), 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
