Some three or four years ago, Mr. Noble exhibited several other crosses, many of which appear to partake of the blood of C. florida, but nothing more has been seen of them till this year, when a group was exhibited at South Kensing ton, which showed that some of them, at least, are destined to secure a share of the public favour. In one of them, the property of fragrance appears to be more fully developed than had been previously noticed. We append a few notes on the several varieties :
MAY QUEEN.- A bright-looking, handsome variety, the sepals eight in number, white down the centre, pale amethyst on the outer edge.
