Raised by Mr. William Smith some years ago from seeds
of a hybrid of R . arhoreum tliat had been fertilized by some
other species, most probably R . ponticum. It surpasses all
the other varieties in the deep-toned purple of its blossoms,
which are also remarkable for their singularly waved appearance.
Our drawing was taken from a plant which flowered
in Mr. Smith’s collection at Norbiton Common, near Kingston,
in the beginning of May.
It should be grown in a mixture of sandy peat and loam.
Tlie plant is apparently quite hardy. For t le explanation
of the generic name see fol. 10. D . Don.
