of pointing out tlie oHect of climate and locality upon certain
species; on tlic other hand, horticu ltu ra lly speaking, the cu ltivator
requ ire s a name by Avhich to recognise a p lan t; and if,
as in the p re sen t instance, th a t name be A . liispidulum, it
matters b u t little Avhcthcr it be a distinct species, or merely
A . jmbcscens, var. hispidiili/m. M'hat the cultivator requires is
a -c o r re c t knowledge of the names of the plants th a t he is
groAving, in order th a t he may be enabled to name them
properly. I f a variety happens to be constant in its peculiarities,
it is as valuable to him as a distinct species.
