Epiphytal. _Stems_ oblong, club-shaped, furrowed in age, and invested in the lower part by whitish membranaceous sheaths. _Leaves_ leathery, ligulate-oblong obtuse, recurved at the tip, deep green. _Scape_ about two-flowered, issuing from the broad compressed leafy sheath, both scape and pedicels tinted with reddish purple. _Flowers_ large, exceedingly attractive from their peculiar striate coloration, the colours very irregularly distributed, no two corresponding parts being alike in marking; _sepals_ lanceolate, slightly recurved, purplish blush, or very dilute lilac-purple, irregularly and striately blotched in the direction of the veins with rich magenta-purple; _petals_ broad, ovate, undulated, irregularly striate-blotched with magenta-purple on the very dilute lilac-purple ground, in the same way as the sepals; _lip_ obovate, emarginate, with a densely frilled edge, the basal lobes enfolding the column of a deep rosy magenta on the outer surface, the middle lobe with a golden blotch on the throat and disk, the front portion striately marked with rich deep magenta-purple outside which is an irregular zone of white, more or less traversed by pale purple veins, the extreme margin being pale purple; otherwise as in the type. Cattleya Mossiæ Hardyana, _Williams and Moore_, supra. This is the most extraordinary variety of _Cattleya Mossiæ_ that has ever come under our notice, and, moreover, it is not only most distinct but most beautiful. Its peculiar coloration is constant, for we have received flowers of it in two successive seasons, and the colour and style of marking have not appeared to vary in the least. We believe it has bloomed three years in succession. Our figure was taken from the fine plant in the noble collection of G. Hardy, Esq., Timperley, Cheshire. This plant we believe is unique, there having been only one example with striped flowers obtained from the whole importation, and that was secured and first flowered by Mr. Hardy, in whose honour it is now named. We know of no other like it, and we must congratulate the owner on his good fortune in obtaining and blooming a variety with such wonderfully variegated flowers. There are many other fine species of Cattleya in this collection, and these bloom magnificently, and are grown to great perfection. They are cultivated in good-sized houses, and have plenty of light, which is a great necessity to these plants, and they also get the proper degree of heat and of moisture, and the annual rest, together with perfect cleanliness, all which seems to be thoroughly understood by Mr. Hill, the gardener, for the plants appear in the same vigorous state of health year after year, and still go on improving.
