lies) 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
