Jus) as a collection apart, many species grown here not being 
represented in the arboretum and fruticetum. Immediately 
beyond the uncompleted north path at the fruticetum is 
a row of poplars, fringing the southerly end of the north 
meadow, consisting of several trees each of Simon’s poplar, 
from China, and Wobst’s poplar, a Russian species. In the 
corner of the salicetum, next to the driveway, is a group of 
willows consisting, in part, of the red-stemmed yellow 
willow, of horticultural origin, and the Ural purple willow. 
To the east of this will be found the golden, or yellow, willow, 
of common occurrence in eastern North America, and Bash- 
ford’s willow, a native of France. Along the west bank of 
the Bronx River will be found a row of trees of the cotton- 
wood, or Carolina poplar, found wild in eastern North Am- 
erica; and another row of the weeping willow, a native of 
Asia. At the northern end of the area devoted to this planta- 
tion are to be found, among others, the purple willow, a native 
of Europe; the black willow, of North America, and the 
pussy willow, a native of the northeastern United States. 
Many other species are represented in this collection. 
6. The Deciduous Arboretum 
This plantation extends over most of the garden area east 
of the Bronx River. The sequence of plant families begins 
at the southeast entrance to the grounds, and continues north- 
ward to the northern boundary, occupying the easterly ridge 
and the low grounds adjacent thereto. Here hardy trees are 
brought together, trees being regarded as woody plants which 
have a single main stem arising from the ground and not 
branching until some distance above it. This collection is 
only partially formed, but additions are made to it every 
season. The groups will be referred to in the order of their 
sequence. 
The first is the willow family which occupies the low-lying 
land near the southeast entrance and the ridge to the north, 
where a collection of willows and poplars may be found. 
Of these Simon’s poplar, from China, is of rapid growth and
