of _Geranium_, has thought it necessary to divide that numerous genus
into three, viz. _Erodium_, _Pelargonium_, and _Geranium_.

_Geranium_, those with ten fertile stamina, his _Batrachia_.

They are continued under the class _Monadelphia_, in which they now form
three different orders, according to the number of their stamina, viz.
