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. Princess Mary (Noble). — This is one of the hybrid varieties of the patens type, bred from C. Standishii, and C. Fortunei, and like others of the same origin, possesses free-blooming and early-flowering properties, which renders it better adapted for culture under glass or in sheltered places, than in others more exposed, though the plants are perfectly hardy.  The leaves are ternate, with ovate leaflets; and the flowers, which are neatly formed, and composed of about eight elliptic sepals, are of a pleasing delicate shade of pale pink, with a whitish bar down the centre of each sepal; the anthers, which are rather conspicuous, and have white filaments, rosy at the tip, being of a brownish or chocolate-purple colour.  An excellent figure of this variety is given in the Florist and Pomologist (1870, 121).

CLEMATIS PRINCESS MARY.
WITH AN ILLUSTRATION. [Thomas Moore]
We now submit to our readers a picture of a charming new Clematis, of the florida race, descended from Clematis Standishii, and one of a fine batch recently obtained by Mr. C. Noble, of Sunningdale. It is the most distinct break we have yet seen from the violets, grays, and whites which are the ordinary colours of the large-flowered forms of Clematis ; and its very pleasing shade of rosy-pink will render it a most welcome acquisition. The niche which this novelty is adapted to fill, is that of an early-blooming hardy or conservatory climber. It is of free but slender growth, with quite the habit of C. Standishii, and like that plant, is adapted either for pot-culture or for planting out in the conservatory, or against a conservative wall. As a spring exhibition plant, blooming freely about the month of May, this, with others of its race, is to be highly recommended. With the double white C. Fortunei, the double blue C. John G. Veitch, and the hybrids Mr. Noble has introduced to public notice, e.g., Miss Bateman, Albert Victor, Lady Londesborough, &c., a very charming group might be made up. Though the exact parentage of the individual seedlings has not been preserved, we learn from Mr. Noble that C. Standishii, Fortunei, and Sophia flore-pleno, with C. lanuginosa (the two former principally the seed-bearers), were the parents of his hybrids,—a race of free-blooming, early-flowering varieties, which, possessing vigour of growth, combine also fine form and unwonted substance of petal, with some exquisite tints of colour. We learn, moreover, that the plants are perfectly hardy.—T. M.
