The _Oncidium hæmatochilum_ is a very compact-growing plant, with leaves from nine to twelve inches in height, and two and a half inches broad, of a dark green colour, spotted with brown. The sepals and petals are of a greenish yellow, mottled with crimson; the lip is of a rich crimson, edged with yellow, and spotted round the margin with magenta-rose colour. It flowers in November, the blossoms continuing for several weeks in perfection, and is a plant that will no doubt become popular, as it blooms at a time when flowers are in request. The specimen we are describing was grown in a basket in the Cattleya house, in peat and moss, which form an unexceptionable compost for it, with good drainage, and a moderate supply of water in the growing season. It is best suspended from the roof where it may obtain plenty of light, but it does not like bright sunshine, and consequently must be shaded in sunny weather.
The Oncidiums are a class of Orchids among which occur some most showy and beautiful species; while almost every colour we could mention is to be found represented among them. They come from different regions, and in consequence their treatment must vary. Some of them rank among our finest exhibition plants, as well as amongst the best for the decoration of our stoves and Orchid houses. We often see fine specimens of Oncidiums in our grand old collections of plants where there is no pretence at growing a collection of Orchids, but where they are merely cultivated for cutting purposes. What is more airy and elegant for vases than the inflorescence of _Oncidium flexuosum_, or even _O. sphacelatum_, or that of many others we could mention if space would allow? What more brilliant than such species as _O. varicosum_ and its variety _O. Rogersii_, _O. ampliatum majus_, _O. tigrinum_, _O. Marshallianum_, or _O. macranthum_?
Dendrobium Findleyanum.—This plant is now (January, 1882) finely in flower in the collection of J. C. Bowring, Esq., Windsor Forest. It must be a grand specimen, as Mr. Clinkaberry, the gardener, informs us that it has one hundred and ninety-two expanded blossoms. We have never before heard of such a well-flowered specimen as this; indeed, large plants of this species are somewhat rare. It is a most curious grower, and very remarkable for its long tapering compressed and deeply nodose stem-like pseudobulbs. The flowers are large, white, tipped with rosy pink, in the same way as those of _D. Wardianum_, and they are produced in great profusion. It is a plant that takes but little room, and should be in every collection.—B. S. W.
