in botany, a genus of the angiospermia order, belonging to the didynamia class of plants, for which there is no English name.—Of this there are two species. The demissiflora, with a single flower upon each footstalk; and the elata, with one or many flowers on each footstalk. The seeds of the first were sent to Mr Miller from Panama. It usually grows about two feet high, and spreads out into lateral branches on every side of the stalk, garnished with oval leaves which are entire, and have short footstalks. Towards the end of the branches, the flowers are produced singly upon pretty long footstalks arising from the wing of the leaf. There are of a light blue colour, sometimes inclining to a purple or red; and there are often three colours of flowers on the same plant. The plant flowers in July, August, and September; and the seeds are ripe in five or six weeks after. The second sort is a native of Peru: the stalk of this plant is twice the size of that of the first, and appears somewhat shrubby; the leaves upon the flower-branches are smooth: the footstalks have some with one flower, others with three, and others with five; which are of a deep violet colour. As both species of browallia are annual plants, they must be raised from seeds, which are to be sown on a hot-bed; but they may be transplanted in June, into the borders of the flower-garden; where, if the weather proves warm, they will flower and perfect seeds; but lest these should fail, there should be a plant or two kept in the stove to secure seeds.
