PLATE CCCCLVI. LACHENALIA FLAVA. _Yellow-flowered Lachenalia._ CLASS VI. ORDER I. _HEXANDRIA MONOGYNIA._ Six Chives. One Pointal. GENERIC CHARACTER. COROLLA 6-petala, infera; petalis 3 interioribus longioribus: stamina erecta: capsula sub-ovata, trialata: semina globosa. BLOSSOM 6-petalled beneath; the three inner petals the longest: chives erect: capsule nearly egg-shaped, three-winged: seeds globular. SPECIFIC CHARACTER. LACHENALIA foliis geminis, lanceolatis: scapo erecto, colore cinereo-cæruleo in modum marmoris variato: corollis flavis, sub-pendulis, sub-cylindraceis, cum limbo petalorum interiorum permagno et expanso: tria petala exteriora angusta, et apice virescentia. LACHENALIA with leaves in pairs, and lance-shaped: flower-stem upright, and of a slaty-colour obscurely marbled: blossoms yellow, nearly hanging down, somewhat cylindrical, with the border of the inner petals very large and spreading: the three outer petals are narrow, and greenish at the point. REFERENCE TO THE PLATE. 1. A flower spread open. 2. Seed-bud and pointal, summit magnified. 3. The seed-bud cut transversely, magnified. This Lachenalia may be regarded as a perfectly new species, there not being a figure of it extant, nor is it enumerated in the Species Plantarum of Willdenow. We were at first inclined to have called it ringens, from the wide-gaping character of the mouth of the flower: but as so many of this genus have received a specific title in reference to their colour, the appellation of flava in the present instance will doubtless be generally as well accepted. The figure was made, from the only plant that has as yet flowered in this country, at the nursery of Mr. Williams of Turnham Green, who informs me that he has had the plant three or four years, but has found it difficult to flower, and slow of increase.
