 of the grounds, including willows in the north meadows, 

 Japanese cherries and a magnolia group in the arboretum,

 long bridge east of the Bronx River; vines and climbers on 

 an arbor east of the economic garden, an iris garden at 

 Pelham Avenue and the Southern Boulevard; lilacs near 

 the museum building and at the foot of the Bronx Boule- 

 vard retaining wall, and conifer groups and rhododendrons

In addition to these artificial features, the following 

 natural features are noteworthy:

 River from the northern end of the hemlock grove to the
