THIS delicate-flowered Heath was raised at the Hammersmith Nursery in the summer of 1820, under the specific title of E. costata, _superba_ (said to be raised from the seed of the E. costata). There were two plants of it that flowered: one tall, the other short and bushy. We preferred the tall one, being the finest and most in flower, but have given a flower from the other plant, which differed a little in shape, and had also two blossoms on it, like the one represented, a kind of monstrosity that sometimes occurs. Upon dissecting the other, we found all the anthers surmounted by the appearance of an increasing petal, and they seemed to have been produced solely at the expense of their fertility, as the absence of the pollen was all the difference we could discern, neither the shape nor colour having suffered any alteration.

HEATH with beardless tips within the blossom: leaves by fours, crowded: flowers sessile, terminating the branches in bunches: a dwarf shrub. DESCRIPTION. STEM low, shrubby: smaller branches are numerous and crowded together at the end of the larger branches. LEAVES mostly grow by fours, linear, flat on their upper surface, and furrowed beneath. FLOWERS sessile, in terminal bunches: blossom bellied and red, the segments of the border are heart-shaped, spreading, and white; of a bright red on the under side. SEED-BUD turban-shaped, furrowed, with honey bearing nectaries at the base. Native of the Cape of Good Hope. Flowers from July till September. REFERENCE. 1. The Empalement. 2. A Blossom. 3. The Chives and Pointal. 4. Seed-bud and Pointal, summit magnified. This Erica resembles the E. primuloides in its foliage, also in the shape and colour of the blossom, but differs greatly in the manner of its growth, as the flowers, in this plant, terminate the branches in complex umbells, more like the genus Daphne than Erica. It is one of those fine seminal varieties raised from Cape seed at the Hammersmith Nursery, and received its specific title in honour of the Earl of Coventry. [Illustration] ERICA crassifolia.
