In the Gardener's Monthly for November, 1877, are some strictures upon the name Populus angulata used by my friend, Dr. Furnas,.of Danville, Indiana, as applied to the Carolina Poplar. His stock was received from Mr. Parry, New Jersey, and through him it came under my notice, in some cuttings received last spring, which have made a growth of three to four feet. For the suggestion of the name angulata, as applied to these plants, I must assume the responsibility, and it may be an error. The conclusion may have been reached too hastily. It was given on the. authority of Michaux' Sylva Americana.

Having been induced to look up the authorities within reach, the following analysis of the genus, the result of this investigation, is presented for the benefit of your readers.
