The singularly graceful deciduous shrub known as C. asplenifolia is the only representative of this genus in cultivation; and though, like its near allies the Myricas, it has little to recommend it as far as flowers are concerned, its fine foliage, pleasing aromatic fragrance, and neat habit of growth, render it worthy of admission to even a select collection of American plants, to which, from its distinct and handsome appearance, it gives a variety which is attractive in the extreme. It is found wild in peaty woods in the colder parts of Canada and the United States, and though it was introduced into Europe nearly a century and a half ago, is as yet rarely found in British gardens; and this is the more remarkable from the fact that it is perfectly hardy, and that it grows freely in the ordinary peat-beds, if planted in a shady aspect. The leaves are of an oblong-linear shape, deeply cut on each side into rounded lobes, resembling small fronds of the well-known fern Ceterach offcinarum; the flowers, which are produced in catkins, are of a rusty-brown colour, and are in perfection about the beginning of April.
