Mr. MILLER, who cultivated this plant in 1731, informs us, that it grows wild about Lisbon, where it covers extensive tracts of ground, in the same manner as the heath does in this country; it seldom rises above the height of three feet, and is much disposed to become bushy; its flowers, which are slightly odoriferous, begin to appear in autumn, and continue during the winter and spring; they grow in little heads on the summits of the branches: their whiteness, contrasted with the dark colour of the foliage, forms a pleasing appearance, and entitles this plant, though a common and long-established inhabitant of the greenhouse, to a place with such as may boast more brilliancy of colour. Its leaves, which thickly cover the stalks, do not well accord with LINNAEUS's specific description. It is usually propagated by cuttings, which strike readily.

SHRUBBY LOBELIA. _Class and Order._ SYNGENESIA MONOGAMIA. _Generic Character._ _Cal._ 5-fidus. _Cor._ 1-petala, irregularis. _Caps._ infera, 2 sive 3-locularis. _Specific Character and Synonyms._ LOBELIA _surinamensis_ caule suffruticoso, foliis oblongis glabris serratis, floribus axillaribus pedunculatis. _Ait. Kew. V. 3. p. 498. Sp. Pl. 1320._ LOBELIA _laevigata_ foliis ellipticis serratis glabris, capsulis grossis globosis, calycibus subulatis, corollis glaberrimis. _Linn. Suppl. p. 392._ The Lobelia surinamensis, a plant newly introduced here, is minutely described in the _Suppl. Pl._ of the younger LINNAEUS, under the name of _laevigata_, apparently from the smoothness of its flowers: in the year 1786, Mr. ALEXANDER ANDERSON sent this plant to the Royal Garden at Kew, from the West-Indies, where it grows spontaneously, as well as at Surinam; and Mr. AITON has inserted it at the end of the _Hort. Kew._ assigning to it a new specific description, and a new trivial name: our drawing was made from a plant which flowered in the stove of Messrs. GRIMWOOD and Co. Kensington, to whom it was imparted by RICHARD MOLESWORTH, Esq. of Peckham, a gentleman liberal in his communications, and anxious to promote the cause of Botany. This species of Lobelia is a stove plant, having a some-*what shrubby stalk, growing to the height of several feet; its blossoms are very large, of a pale red colour, and its Antherae, which might be mistaken for the stigma, unusually hairy. It begins to flower in January and February, and continues to blossom during most of the summer. Is increased by cuttings. [226] ARABIS ALPINA. ALPINE WALL-CRESS. _Class and Order._ TETRADYNAMIA SILIQUOSA. _Generic Character._ _Glandulae_ nectariferae 4, singulae intra calycis foliola, squamae instar reflexae. _Specific Character and Synonyms._ ARABIS _alpina_ foliis amplexicaulibus dentatis. _Linn.
