which includes a sweep of the Hudson and the mouth of Spuyten 

 Duyvil Creek. The path to the cHff leads to a road near the 

 cliff edge and here we find among the ruins of old buildings a 

 variety of interesting plants. The white willow, which is not 

 of common occurrence, appears to be established here; and 

 clinging to old masonry with a little soil mixed with crumbing 

 mortar I have found the Kenilworth ivy, Linaria Cymbalaria, 

 a pretty little creeping herb, apparently encouraged by the 

 presence of the lime, and well established. There are many in- 

 teresting and handsome planted specimens of exotic and intro- 

 duced trees and shrubs to be seen on the hill, such as the copper 

 or purple beech, Austrian pine, paulownia, weeping cutleaved 

 birch, etc. A tree of the red ash grows near the cliff road and 

 has been apparently planted. Another individual, probably 

 native, many be seen just northwest of the Dyckman Institute 

 building in the Shorakapkok Glen and close to the river. The 

 twigs and leaves are downy and the habit is more spreading 

 than in the white ash. The large white pines growing on Cock 

 Hill are probably planted. 



A proposed List of Plants of Inwood Park. It would be in- 

 teresting and certainly valuable as a record to have a complete 

 list of the plants growing at the present time in Inwood Park, 

 as well as the other parks of greater New York — at least for 

 those which are still fortunately maintained in a wild or semi- 

 wild condition. This might form an objective for some of the 

 Club's field trips in the future. That the flora of Inwood has 

 changed, the following list of orchids collected there, in 1866-8 

 chiefly by Dr. H. M. Denslow, his uncle Mr. W. W. Denslow, and 

 others, bears witness. These plants seem to have long since 

 vanished.^ The data for this list have been kindly furnished by 

 Mrs. Palmyre DeC. Mitchell of the New York Botanical 

 Garden. 



1. Orchis spectahilis L. May 14, (no year given, but evidently 



1887. See Bull. Torr. Bot. Club 14: 153. 1887.) Miss

2. Pogonia trianthophora (Sw.) BSP. "N.Y. Island" Wm. 



Bower, 1866.
