Rhus. ANACARDIACE.E. 131 



petiole an inch or more in length. Flowers yellowish-green, dioecious. Fruit the size of a 

 small pea, greenish or pale brown. Nut broader than long, irregular, ribbed and tuberculate. 



Woods, hedges, along fences, etc. Fl June. Fr. September. 



Poisonous like the preceding, but in a less degree. The dwarf upright form of this plant 

 is not uncommon on the borders of woods, and on rocky hill-sides. It is certainly not a distinct 

 species. In the more common or climbing state, its numerous stems sometimes become mat- 

 ted together, and finally strangle the tree to which they are attached. The plant thus assumes 

 an arborescent appearance, the trunk and decayed branches of the tree being concealed by the 

 stems and foliage of its destroyer.

 globose, villous : nut smooth, compressed : flowers in short ament-like spikes or panicles, preceding

A small shrub ; the branches of a light brown color, and pubescent when young. Leaves 

 li - 2h inches long, at length coriaceous. Inflorescence in the form of numerous small dense 

 ament-like axillary racemes, which are formed the preceding summer. Scales reddish, with 

 a hairy border. Flowers yellow. Fruit the size of a small pea, light red, more or less hispid, 

 slightly compressed, acid. 



Dry rocky hills and gravelly banks, north and west of Catskill. April - May. The specific 

 name is inappropriate, as the flowers are not aromatic. To many persons they are unpleasant.
