_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, naked. SPECIFIC CHARACTER. ORNITHOGALUM racemo longo: floribus magnis, flavissimis: bracteis membranaceis, ovato-acutis: foliis lanceolatis, reflexis. Ornithogalum flavissimum. _Jacq. Icones, 2. tab. 436._ STAR OF BETHLEHEM with a long spike: the flowers are large, and very yellow: the flower-prop is skinny, and pointedly egg-shaped: leaves lance-shaped, and reflexed. REFERENCE TO THE PLATE. 1. A bract or flower-prop. 2. Seed-bud, chives, and pointal. 3. Seed-bud and pointal, summit magnified. 4. A transverse section of the seed-bud magnified. This yellow Ornithogalum was communicated to the author by the Hon. W. Irby, last summer, from his collection at Farnham Royal, where it was raised, we understand, from the seed of the O. aureum. The only figure of it extant is in the Icones of Jacquin. The continuance and abundance of its fine bloom may justly rank it amongst the most attractive of the genus. ERRATUM.--In our last Number, Pl. DI, in the generic character of Hellenia describing the capsule, instead of trivalvis, septo duplici inclusa, read e-valvis, trilocularis--valveless, three-celled.
