Note B — Plate 4.

As stated under Plate 3, this plant had been supposed to be a form of C. angustifolius, and that name has unfortunately been printed upon the plate. It proves to be an entirely new species, well characterised by the very slender curved basal part of the flower-tube, and the long, tapering and very acute tips of the leaves, which are narrowed at the base into terete petioles, and also, to judge from the figure, are not produced at the same time as the flowers. In the true C. angustifolius, Aiton, the flowers and leaves are produced at the same time, the latter are flat to the base and very shortly pointed at the tips; the tube of the flower gradually narrows from apex to base without being contracted into a very slender basal part, and is less curved there.

There is a large-flowered variety of C. angustifolius known as var. grandiflorus, Baker, which does not seem to be clearly understood in South Africa. A good figure of it, but reduced in size, appears in the Gardeners’ Chronicle, 1905, vol. 37, p. 261, f. 110, No. 2.—N. E. Brown.
