By H. B. Ellwanger, reprinted from the proceedings of the Western New York Horticultural Society. This is one of the most interesting papers that have been contributed to horticulture for some time past. Mr. Ellwanger has looked up all the American varieties of roses, and has given a brief sketch of their history. These number fifty-three. The list might doubtless be enlarged, and it would be doing good service if those who know of others would send some account of them to Mr. Ellwanger. Sherwood's Musk Cluster was a famous rose in its day among Philadelphia florists, and we fancy is yet to be found in some collections.
