This remarkable _Odontoglossum_ was long since discovered in New Granada by Schlim and Wagener, in whose herbaria its stately many-flowered panicles formed so striking a feature that Professor Reichenbach did not hesitate to give the plant the name of _gloriosum_; an epithet which--now that we have the plant amongst us in a living state--may perhaps be thought to be somewhat beyond its merits. It must indeed be admitted that the fresh blossoms, which are of a faint yellowish-green, scarcely realize the expectations which the rich colour and profusion of flowers in the dried specimens had very naturally raised. Nor are all the varieties of equal merit, some being much smaller and paler than others. The species has lately been imported in large quantities, both by Messrs. H. Low and Co., of Clapton, and by the Horticultural Society, who received it in 1864 from Mr. Weir, by whom it was gathered in the neighbourhood of Bogotá. It flowers freely, and at all seasons of the year; nor does it appear to care so much as many of its congeners for a few degrees more or less of heat or cold. I believe it has already bloomed in almost every collection of note; though the spikes, as was of course to be expected, are as yet far from equal to the wild specimens.[8] The figure was taken from a plant in Mr. Day's garden, where I saw, in November last, nearly a dozen distinct varieties in blow, some of them rivalling the example given in the Plate, while others were as insignificant as that which is shown in the vignette. The blossoms continue fresh for at least a fortnight, and emit a pleasant honey-like scent. [Illustration] DISSECTIONS.--1. Lip (_magnified_), seen sideways; 2. Ditto, seen in front.
