when they will be found face to face, instead of spread apart. 

 Both sterile and fertile flowers are found on the honey locust, 

 and they are both somewhat irregularly unequal, arranged 

 in finger-shaped clusters and greenish in color. They con- 

 tain great quantities of nectar and are much visited by bees. 

 The subsequent fruits are pea-like but much longer than ordi- 

 nary garden peas, frequently exceeding a foot in length. 

 The seeds are flat and oval. 



The durability of the wood of the honey locust when 

 underground has made the tree much prized for fence posts 

 and railroad ties. It grows wild from Ontario to Pennsyl- 

 vania and Florida; most of the trees in the Hudson Valley 

 are presumably naturalized as it seems not to have been 

 ancestrally wild in the valley. To-day it is common. 



The locust (Robinia Pseudacacia) is not a wild tree in the 

 Hudson Valley but has become naturalized from its fre- 

 quent cultivation. Its trunk is covered with deeply-Assured 

 bark, and often forks into several main branches. The 

 flowers are in clusters, white, and are much like a common 

 pea. The pods are quite smooth. Naturally the tree is 

 confined to a narrow belt stretching from southern Pennsyl- 

 vania to Georgia. Its wood is very hard and durable. 



The clammy locust {Robinia viscosa) may be distin- 

 guished from the preceding by its smaller stature, red or 

 pinkish flowers, and hairy pods. Its natural range is con- 

 fined to a small area in Tennessee and North Carolina; the 

 many wild trees in the Hudson Valley are escapes from 

 cultivation. 



Staghorn Sumach Rhus hirta 



Most of the sumacs are shrubs, but an occasional tree 

 30 feet high may be found. The bark on the trunk and 

 larger branches is smooth and brown; very rarely it splits 

 up into small plates. 



The compound leaves are from 16 inches to 2 feet long, 

 hairy, and composed of from 11 to 31 leaflets, all attached 

 to the common, reddish, or greenish-red leaf-stalk. The 

 leaflets are themselves practically stalkless, lance-shaped or
