The leaves of these plants are so subject to vary in
form, especially in the degree of dentation, that so little

dependence






dependence can be placed upon this character, that Mr.
Brown pointed out to us a specimen containing the foliage
of integrifolia, oleæfolia, and glauca of Cavanilles, 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.
