two writers would exactly agrce. Some of these varieties are in

the species in the ‘ Gardener's Chronicle’ of 1871, of which we

in its entirety, as nearly all the species are in our gardens ; but 
we must limit ourselves to details of those species known to be in 
cultivation. All the species flower in Summer or early Autumn.
