Epidendrum vitellium.—A very fine spike of this charming species was received by us from H. Shaw, Esq., of Buxton; it was eighteen inches in height and bore twenty-one of its orange-scarlet flowers, of good size and stout substance. This was certainly the best spike that has ever come under our notice. Mr. Shaw calls it _E. vitellinum giganteum_. The plant it appears has borne five spikes equally as good as the one which was sent to us. There is no doubt that it is a gigantic form of the old species, much finer than some of those called _majus_, which generally flower in spring and summer while this one blooms in December which fact alone makes it a valuable acquisition, as we have so few Orchids of this colour blooming at that time of year, December and January.—B. S. W. [Illustration: PL. 127. ODONTOGLOSSUM ALEXANDRÆ STEVENSII.] ODONTOGLOSSUM ALEXANDRÆ STEVENSII. [Plate 127.] Native of New Grenada. Epiphytal. _Pseudobulbs_ ovate-oblong, compressed, generally in age becoming tinged with purple, diphyllous. _Leaves_ ligulate-oblong acute, channelled towards the base, of a bright light green colour, often with one or two accessory ones from the base of the pseudobulbs. _Scapes_ radical, issuing from the axils of the accessory leaves, and supporting a many-flowered raceme, or, in very vigorous plants, a panicle of flowers, having small acute bracts at the base of the pedicels. _Flowers_ large, and handsomely-spotted; _sepals_ lanceolate-acuminate, undulately recurved at the edge, white, marked with three large oblong blotches of pale cinnamon-brown, the two lower bands transverse; _petals_ broader, ovate acuminate, the margins toothed, much undulated, the surface freely spotted all over, especially towards the margins, with the same tint of pale cinnamon-brown, the spottings forming smaller roundish or oblong dots, which are sometimes confluent, while numerous smaller ones occupy the base; _lip_ oblong-ovate acuminate, with a deeply cordate base, and a toothed undulated margin, the disk occupied by a broad patch of yellow; the other parts white, with one large conspicuous blotch of brown near the apex, and a few smaller ones behind it, the base marked with numerous small crimson dots, radiately cristate, with two of the lamellæ elongated, and most of them marked by a crimson line.
