Epiphytal. Acaulescent. _Leaves_ distichous, coriaceous, oblong acute, recurved, channelled and equitant at the base, of a dull green, the upper surface boldly chequered with oblong markings of darker green, the under side keeled with the surface paler and unspotted. _Scape_ (peduncle) pubescent, dull wine-purple, with a short compressed ovate bract just below the ovary, which is green striped with brown. _Flowers_ solitary, remarkable for the small dorsal sepal and large pouch; _dorsal sepal_ short, ovate acuminate, curving from the base upwards, greenish with a white edge and about ten greenish-purple nerves; _lateral sepals_ united, very small, ovate, greenish with green veins; _petals_ measuring about four inches from tip to tip, linear-oblong, acute, wavy, recurved at the tips, greenish in the upper, white in the lower half, indistinctly veined with purple, and thickly spotted with small purple dots, the margin copiously fringed throughout with short purple hairs; _lip_ with a large oblong bluntly-rounded pouch (one and a half inch long) of a dull wine-purple with a few prominent darker purple veins, the upper edge of the sac with narrow side angles greenish inside, the basal part with the edges rolled inwards and dotted with purple. _Staminode_ transversely oblong, emarginate behind and having in front an inwardly curved tooth on each side with an apiculus between, pale yellowish green, with darker green reticulations in the centre. Cypripedium Curtisii, _Reichenbach fil._, in _Gardeners’ Chronicle_, N.S., xx. 8. This new species is both distinct and rare. It is, moreover, very beautiful and one that every lover of Cypripediums will be looking after. There are some cultivators who do not care for this class of Orchids, and there are some others who grow all the species and varieties they can procure, making the collecting of them a hobby. We can fully understand the pleasurable feelings of these latter, as the plants are ornamental in foliage as well as in flower, thus always keeping up a good appearance; they are also very easy of cultivation, and most of them take but little room to grow in. There are now so many species and varieties—blooming, too, at different periods of the year—that a good display of flowers may always be had from them; and there are some of the species that will do in the Odontoglossum and intermediate houses, added to which their long-enduring quality scores as a great point in their favour. We are never without Cypripediums in bloom.
