This species of the stinging spurge appears to be quite 
distinet from T. nepetaefolia in the floral characters and in the 
stiff erect habit of growth. The latter is usually a more or 
less twining vine, sometimes 5 m. high or more.

This shrub, commonly known as polecat bush, is quite dis- 
tinet from Rhus canadensis. It is usually found on dry lime- 
stone ledges or rocky bluffs and is a stout shrub 1 to 1.5 m. 
high, with stems sometimes 4 or 5 em. in diameter. It flowers 
much later than R. canadensis, the leaves being more than half 
grown at the time of blooming. R. canadensis, a slender shrub, 
is one of the earliest flowering plants of spring.
