This species of Erica in the mutability of its flowers resembles the blossoms of the _E. colorans_. It was first raised from Cape seed at the Hammersmith Nursery in the summer of 1825, under the appellation of _ruber-calyx_: a specific title of one word would have been preferable, but it is very characteristic of the plant when in bloom, which is a recommendation not often to be met with where the best specific titles are already occupied. It is a handsome dwarf shrub, with abundance of successive bloom. [Illustration] ERICA rugosa. CHARACTER SPECIFICUS.

HEATH, with tips two-horned at their base, just without the blossom; flowers nearly terminal, wrinkly, and red: leaves linear: branches many. DESCRIPTION. STEM shrubby, upright, two feet high: branches grow by threes, in whorls. LEAVES in irregular whorls, of 3 to 5 linear, slightly curved, and spreading; footstalks long. FLOWERS nearly terminal: blossom nearly tubular, spreading, wrinkly, and of a deep red colour; segments of the border spreading: footstalks long and coloured. SEED-BUD turban-shaped, furrowed, red at the base, with honey-bearing nectaries, villose on the upper part. Native of the Cape of Good Hope. Flowers from the month of June till August. REFERENCE. 1.

THIS curious species of Erica was raised from seed at the nursery of Mr. Rollinson about the year 1806, from which period it has flowered abundantly; but all attempts to increase it have hitherto proved abortive; and whether the wrinkly character of its blossoms would be continued were it to seed with us, is certainly doubtful, as it appears to be a contraction in the flowers bordering upon monstrosity; and we at first declined figuring it, expecting the wrinkles would not appear when next it bloomed; but for four successive summers it has still retained its strange appearance, more singular than beautiful, but probably more interesting by its oddity.
