(R. pseud-acacia), so called from the color of its wood ; and 
the Honey locust ( R . viscosa), a smaller tree, with reddish 
flowers, and branches covered with a viscid honey-like gum. 
Some pretty varieties of the former have been originated 
in gardens abroad, among which the Parasol locust ( Var . 
umbraculifera) is decidedly the most interesting. We 
recollect some handsome specimens which were imported 
by the late M. Parmentier, and grew in his garden at 
Brooklyn, Long Island. They were remarkable for their 
unique, rounded, umbrella-like heads, when grafted ten or 
twelve feet high on the common locust. 
There are two pretty distinct varieties of the common 
Yellow locust, cultivated on the Hudson. That most fre- 
quently seen is the White variety, which forms a tall and 
narrow head ; the other is the Black locust, with a broad 
and more spreading head, and larger trunk ; the latter may 
be seen in fine condition at Clermont. It is a much finer 
ornamental tree, and appears less liable to the borer than 
the White variety.

This tree is often called the Three-thorned locust, from 
some resemblance to the latter tree. Its delicate, doubly 
pinnate leaves, however, are much more like those of the 
Acacias, a family of plants not hardy enough to bear our 
climate. It is a much finer tree in appearance than the 
common locust, although the flowers are greenish, and 
inconspicuous, instead of possessing the beauty and fra-
