As before noted, the plant which we can buy under this name in many nurseries for twenty-five cents, we may also buy for seventy-five cents, under the name of "Russian Thornless Acacia," in others. The excuse for adopting a few score of common names in the place of one Latin one for a single plant, is generally that the botanical name is so long and so hard : but we see no advantage in this respect in "Russian Thornless Acacia" over Caragana, especially when it costs us an extra fifty cents to learn it.
