Spring Flowering Clematises.
Mr. Noble, of Sunningdale, has produced some beautiful hybrids belonging to this class. They comprise Albert Victor, deep lavender, with brown ribs along the centre of each petal; Harry Richmond, lavender-grey, each petal having a flame of deep violet; Lord Londesborough, rich mauve, the petals having the centre stripe of maroon; Lady Londesborough, silver-grey, with flame of white; Mrs. Villiers Lister, cream tinted with pink, and bars of maroon; Mrs. Howard Vyse, white, each petal edged with mauve; Miss Bateman, pure white, very fine stout flowers; Princess Mary, pink, suffused with puce, each petal having a pale stripe; and Queen Guinevere, creamy white. Mr. Noble has other varieties, but the foregoing have been repeatedly shown, and therefore a definite opinion can be formed as to their merits.

Descriptive Notes of Species & Varieties.
C. Lord Londesborough (Noble). — One of the finer of the hybrid varieties of the patens type raised from C. Standishii by Mr. Noble.  As in the species just referred to, it has ternate foliage, with small ovate leaflets.  The flowers are from five to six inches across, and consist of about eight sepals, the colour of which is a deep mauve or bluish-lilac, with a coppery-tinted purplish-red bar running down the centre of each; the filaments are white, red at the base of the anthers, which latter are chocolate-purple,  They are produced in the spring months; in March if gently accelerated, in May if flowered naturally in the open air.  As in all the early-blooming sorts, however, its chief value will be for cool conservatories or corridors, having the protection of glass.  It was awarded a First-class Certificate by the Royal Horticultural Society, in 1870.
