This interesting novelty requires the same treatment as _C. Stonei_, that is, to be potted in rough fibrous peat, intermixed with some charcoal and sphagnum moss; good drainage must also be afforded, as the roots must be kept moist during the growing season; in fact, they should never be allowed to get dry, as it has no thick fleshy bulbs or stems to support it. We find it do well in a warm house with other Cypripeds. Pot culture is the most suitable for it, but it will succeed in baskets suspended from the roof, if shaded from the sun. Odontoglossum Alexandræ.—We have received a splendid variety of this popular Orchid from J. S. Bockett, Esq., of The Hall, Stamford Hill. The inflorescence was very distinct, and consisted of flowers of good form and substance, with the margins beautifully serrated. The sepals and petals were white flushed with rose, the sepals being in addition spotted with reddish brown, and the white lip was also spotted with brown. The flowers were, moreover, nicely regulated on the spike, so that the entire inflorescence had a particularly good appearance.—B. S. W. [Illustration: PL. 120. DENDROBIUM DEAREI.] DENDROBIUM DEAREI.
