Of this fine stove plant there is a very good figure in the Hortus Schœnbrunnensis of Jacquin, under the appellation of Justicia cristata. But finding the generic character accord much better with the genus Ruellia, we have, in conformity to the sexual system of Linnæus, given it under that title. Our figure represents only a side branch of the plant, whose size was congenial to the dimensions of the work; and although the centre branch would have been, like Jacquin’s figure, more splendid, it would by no means have been so picturesque. It flowered for the first time in this country with A. B. Lambert, esq., and was introduced by Lord Seaforth from the West Indies. [Illustration] PLATE DVII. PROTEA ABROTANIFOLIA. _Southernwood-leaved Protea._ CLASS IV. ORDER I. _TETRANDRIA MONOGYNIA._ Four Chives. One Pointal. ESSENTIAL GENERIC CHARACTER. COROLLA 4-fida, seu 4-petala. Antheræ lineares, petalis infra apices insertæ. Calyx proprius, nullus. Semina solitaria. BLOSSOM four-cleft, or of four petals. Tips linear, inserted into the petals below the points. Cup proper, none. Seeds solitary. SPECIFIC CHARACTER. PROTEA foliis bipinnatis, filiformibus, glabris: floribus terminalibus, umbellatis: pedunculis longis, bracteis magnis, reflexis: corollis carneis, externe villosis. Habitat ad Caput Bonæ Spei. PROTEA with doubly-winged leaves, thread-shaped, and smooth: flowers terminate the branches in umbels: footstalks are long, with large reflexed floral leaves: blossom flesh-coloured, and hairy on the outer side. Native of the Cape of Good Hope. REFERENCE TO THE PLATE. 1. A leaf. 2. A flower with its bract, one tip magnified. 3. Seed-bud and pointal, summit magnified. 4. A branch of a slight variety. This Protea is one of a fine section with small divided leaves, that very much resemble the southernwood (whence our specific title). We have already four drawings of distinct species, besides varieties, whose foliage is likewise characteristic of that shrub. On the same plate we have given part of the branch of a variety that we think bears too much resemblance to require a separate figure. Our drawing was made last July from plants in the Hibbertian collection. [Illustration] PLATE DVIII. CACTUS GRANDIFLORUS. _Large-lowered Cereus._ CLASS XII.

EMPALEMENT one-leafed, above, tiled. Blossom of many folds. Berry of one loculament, many-seeded. SPECIFIC CHARACTER. CACTUS scandens vel repens, ramosus, articulatus, cum radiculis lateralibus: ramis sex-vel octagonis, aculeos stellatos ferentibus. Calyx radiatus, flavus: corollis albis. Flores magni, vesperè expansi, odorem fragrantissimum exhalantes.
