back of the anthers. Ovarium 5-ahgular, clothed with a
silky tomentum. Style smooth, ascending, longer than the
stamens. Stigma capitate, rugose, viscous.
The present singular and handsome plant is of hybrid
origin, and was raised from seeds in the superb collection
of American plants at the Earl of Carnarvon’s, at High-
clere; the seed was procured from Azalea nudifiwa or
viscosa, that Mr. J. R. Gowen had fertilized with the pollen
of a hybrid Rhododendron, between R. ponticum and
R. catawbiense; and we are informed by that gentleman,
that there is in the same collection “ nearly a hundred seedlings,
very healthy plants, two years old: they are all from
Azaleas; from different varieties of A. viscosa and nudi-
Jlora, are all free growing plants, evergreeen in ordinary
Winters, but in severe frost showing a tendency to shed
their leaves more or less: they were procured by fertilizing
the Azaleas with the pollen of Rhododendrons, that are intermediate
between R. ponticum and catawbiense.” In
the same collection are numerous hybrid Azaleas, between
most of the different species and varieties, and also plants
from the hybrid R. catawbiense and ponticum, with R. ar-
loreum, so that in the course of a few years we may expect
this tribe of plants to rival if not exceed all others.
In the Earl of Liverpool’s collection, at Coombe-wood,
there are numerous plants of hybrid production, between
R. arboreum and R. ponticum, also between the former
and Azalea pontica and other sorts; and in Mr. Russell’s
Nursery, at Battersea, there are others between R. arboreum
and R. catawbiense. By the different species of Rhododendron,
Azalea, and Rhodora, mixing altogether so freely,
there can be no reason for keeping them apart as distinct
genera. They all succeed well in peat soil, or light sandy
loam.
Our drawing was made from a fine specimen kindly sent
to us by J . R. Gowen, Esq. the beginning of last June, and
in compliment to him we have named the present subject.
The generic name is derived from poSov, a rose, and
SevSpov, a tree, from the plants generally bearing rosy-coloured
flowers.
