Though long since described, we have been in possession of this species of Crane's-Bill but a few years; it is one of the many new ones introduced by Mr. Masson from the Cape, and at the same time one of the most desirable, as its blossoms which are ornamental, are freely produced during most of the summer, and the plant itself is readily propagated by cuttings.
The flowers vary considerably, both in size, and colour; its foliage is different from that of most others, and, as its name imports, like that of the Birch-Tree.
It requires the same treatment as most other Green-House Plants.
