THE KALMIA.
The Kalmia, on account of its superficial resemblance to the green bay-tree, often called the American laurel, is more nearly allied to the heath. The name of Kalmia, which is more musical than many others of similar derivation, was given to this genus of evergreen shrubs by Linnæus, in honor of Peter Kalm, a distinguished botanist and one of his pupils. This is exclusively an American family of plants, containing only five species, three of which are natives of New England soil and two of them among our most common shrubs.
