The East India house is the most suitable place in which to cultivate it, for most of the species of _Zygopetalum_ like the temperature therein maintained, and, indeed, they thrive well in any warm stove. This new species will no doubt require as a root medium the same material as the rest of the genus, that is, rough fibrous peat and loam. As they generally have thick fleshy roots, they require an abundant supply of moisture during the growing season; but of course a less liberal supply will suffice after the growth has been completed, when the ripening process comes on. A Wonderful Dendrobium.—Mr. Blend, gardener to S. K. Mainwaring, Esq., Otley Park, Shrewsbury, has recently flowered a grand specimen of the old and beautiful _Dendrobium Paxtoni_. The plant is in a 15-inch pot, has 74 growths, and produced 123 flower spikes, containing in all 1,216 flowers. The longest growth on the plant measures as much as four feet six inches. This plant is a marvel of cultivation, and we are much pleased to be able to record such a splendid example of Orchid management—B. S. W. Odontoglossum mulus.—D. Tod, Esq., Eastwood Park, Thorliebank, by Glasgow, has sent in flowers of a fine variety of _Odontoglossum mulus_, which bloomed with him last April. The spike, Mr. Tod informs us, bore sixteen flowers, and although this is no great number for _O. mulus_, which generally comes with a large branched panicle, it must have been a fine sight, as the flowers of Mr. Tod’s variety are not only very large, but very brightly coloured.—B. S. W. A Gigantic Orchid.—Messrs. F. Sander & Co., of St. Albans, have lately received an enormous specimen of _Cattleya Skinneri_, certainly the largest mass of an Orchid ever imported. The plant was found growing in the crown of a tree, near Cartago, in Costa Rica, where it was originally planted in a garden belonging to a native, by whom it has since been cultivated, so that although this plant has been found in its native habitat, it is, nevertheless, a cultivated specimen. This plant has long been known to botanical travellers, Skinner, Roezl, and others having seen it in flower. It is stated to have produced, at one time, over 1,500 flowers. Its dimensions are six feet in height by seven feet in diameter; its weight about twelve hundredweight. We understand Mr. Sander is about erecting a house for its reception, where we suppose it will figure as a _piece de resistance_ of the establishment.—H. W. [Illustration: Pl. 143.
