Vanda Sanderiana.—It is with great pleasure that we are able to announce the flowering of this magnificent novelty, in the collection of W. Lee, Esq., Downside, Leatherhead, where it may now (September) be seen, bearing three spikes of its gorgeous flowers. One spike bears twelve flowers, and another eight. If the reader will imagine a dozen of these lovely blossoms, each from four to four and a half inches in diameter, collected together on one spike, he may form some idea of the magnificence of this grand novelty. In growth the plant resembles a gigantic _V. cœrulea_, but having much broader and longer leaves, and stouter stems and flower-spikes than that species. The spikes are produced from the axils of the leaves in an erect position. The leaves are from nine to twelve inches long, and about an inch broad, deeply channelled. The flowers are fully four inches in diameter; the upper sepal and the two petals are nearly of one size and of a blush-pink, about the colour of a pale variety of _Odontoglossum vexillarium_; the lower sepals are much larger and broader than the petals, two inches across, tawny yellow distinctly and beautifully reticulated with dull crimson over the entire surface; the lip is dull brownish crimson, and has three keels along the centre extending from the apex to the base. The contrast of the crimson markings on the yellow sepals renders this new Vanda one of the most distinct species we have ever seen. We have had a sketch of this plant prepared, and it will shortly be presented to our readers.—H. W. [Illustration: PL. 112. CATTLEYA SKINNERI ALBA.] CATTLEYA SKINNERI ALBA. [Plate 112.] Native of Costa Rica.
