The radical leaves of plants usually differ in shape from those of the
stalk, in some plants remarkably so; the _Lepidium perfoliatum_ figured
in the _Flora Austriaca_ of Professor JACQUIN is a striking
instance of this dissimilarity: the _Lathyrus Aphaca_, a British plant,
figured in the _Flora Lond._ is still more such, as large entire
leaf-like stipulæ grow in pairs on the stalk, instead of leaves, while
the true leaves next the root, visible when the plant first comes up
from seed, are few in number, and those pinnated. The present plant no
less admirably illustrates the above remark, the leaves which first
appear on the seedling plants being pinnated, as is represented in the
small figure on the plate, while those which afterwards come forth grow
in whorls. We have observed the same disposition to produce dissimilar
leaves in several other species of _Mimosa_, which have arisen from
Botany-Bay seeds, lately introduced.
