EMPALEMENT 5-parted. Blossom one petal: border 5-lobed, unequal. Chives by pairs. Shaft thread-shaped. Summit two-cleft. Capsule with the partitions toothed, elastic, and splitting. Seeds few. SPECIFIC CHARACTER. RUELLIA foliis petiolatis, ovato-acuminatis, undulatis, pilosis, crenatis: pedunculis axillaribus, cum multis floribus tubæformibus. RUELLIA with petiolated leaves ovately pointed, waved, hairy, and scolloped. Footstalks axillary, with many long trumpet-shaped flowers. REFERENCE TO THE PLATE. 1. The empalement. 2. A blossom spread open. 3. Seed-bud and pointal. 4. The capsule. 5. The same split open. 6. A ripe seed. This new and beautiful species of Ruellia was introduced by Lord Seaforth from the West Indies, and flowered in Mr. Lambert’s stove at Boyton, in June 1807, for the first time in England; and continued, as he informs us, to flower during the greatest part of the summer, ripening its seeds in abundance, and being easily propagated by cuttings. [Illustration] PLATE DXXVIII. ORNITHOGALUM ELATUM. _Lofty Ornithogalum._ CLASS VI. ORDER I. _HEXANDRIA MONOGYNIA._ Six Chives. One Pointal. ESSENTIAL GENERIC CHARACTER. COROLLA 6-petala, persistens. Filamenta basi dilatata. Capsula 3-locularis. Semina subrotunda, nuda. BLOSSOM 6-petalled, remaining. Threads widened at the base. Capsule 3-celled. Seeds roundish and naked. SPECIFIC CHARACTER. ORNITHOGALUM foliis lanceolatis: floribus in racemo longissimo crescentibus, albis et parvis: staminibus longitudinem corollarum fere æquantibus. ORNITHOGALUM with lance-shaped leaves. Flowers grow on a very long spike, are white and small. The stamens scarcely the length of the blossoms. REFERENCE TO THE PLATE. 1. A petal and chive. 2. A chive shown from the outer side. 3. Seed-bud and pointal. 4. The same magnified. This tall and delicate plant was introduced by J. M. Cripps, esq., who found the roots in Egypt on the plains of Alexandria, near the spot where the famous battle was fought in the year 1801; and from one which he planted in his garden at Staunton in Sussex our drawing was made. It agrees in habit with the Ornithogalum latifolium, but is perfectly distinct both in the blossoms and foliage from that species. The plant which our figure represents had already produced four side bulbs. It flowered in March last, and appears to propagate freely. [Illustration] PLATE DXXIX.
