Our figure represents a fine new species of Erica communicated from the extensive collection of His Grace the Duke of Bedford at Woburn Abbey, where it was raised from seed in the summer of 1824. In its foliage it very much resembles the _E. tenuiflora alba_, figured in our third volume; the principal if not the only distinction is, when in bloom, the delicacy of its flowers, whose fine blush-colour gives it a decided preference over the white variety. It is considered as a variety through the medium of the _E. spuria_, a mule to which the genus is indebted for many fine variations. [Illustration] ERICA Thunbergia. CHARACTER SPECIFICUS.

THIS Erica is said to be first described by Professor Montin in the Upsal Transactions. It is a very interesting plant, combining beauty with novelty, and perfectly distinct from any other species at present known: it bears the name of that able botanist Thunberg, and was first raised at the Hammersmith Nursery from Cape seed brought by the late F. Masson, Collector to the Royal Gardens at Kew. [Illustration] ERICA transparens. CHARACTER SPECIFICUS. ERICA, antheris muticis, inclusis: floribus terminalibus: foliis ternis. DESCRIPTIO.
