The leaves of these plants are so subject to vary in form, especially in the degree of dentation, that so little dependence can be placed upon this character, that Mr. pointed out to us a specimen containing the foliage of integrifolia, oleæfolia, and glauca of, all growing on the same plant; the reticulated veins on the undersurface, conspicuous through the tomentum in australis, distinguishes that species, and some others, from all the va- rieties of marginata, in none of which is there any visible veining.
