We now present to our readers a portrait of a most splendid variety of _Cattleya Trianæ_, of which them are numerous handsome forms, varying in colour from rose to crimson and magenta, and also to pure white, with intermediate tints. During the past five years there have been very large importations, but none that we have seen surpass the varieties we have already in cultivation, such as _Dodgsoni_, _Osmanii_, _Russelliana_, and _Williamsii_. These varieties are most difficult to improve upon, but probably we shall get other splendid forms among the large importations as they come to us from the different districts which the species inhabits. The _Trianæ_ section has given us a grand lot of varieties for winter decoration especially; there are very many distinct types among them, and they come into blossom at a time, during the dull months of winter, when flowers are wanted to make our houses gay. Our drawing was taken from a very large specimen that has been grown and bloomed by us for several years, and which we consider one of the most beautiful varieties in cultivation—we believe our plate will show us to be fully justified in so doing. _Cattleya Trianæ formosa_ is a free and strong-growing evergreen kind, attaining fifteen inches high, with dark green foliage and strong sheaths. The flowers are of large size and substance, and are thrown well up so as to have a bold appearance, much more so than many others of its class. The sepals and petals are of a blush pink, and the lip rich rose-magenta, being beautifully frilled and edged with a lighter tint of the same colour, two and a quarter inches in diameter, have the throat orange veined with a deeper orange. The flowers are produced in February and March, lasting for several weeks in beauty. It thrives best in a pot with rough peat and good drainage, and requires the same treatment as _C. Mossiæ_ and _C. Trianæ_, beginning to grow after it has finished blooming. These make their flower sheaths in summer, much earlier than most of the _Cattleyas_, which secures to this section more light and heat in which to finish off their growth before winter sets in. Their pseudobulbs must be kept dry during winter, as if allowed to get wet they will probably rot away; therefore, when their growth is finished, give only sufficient water to keep the pseudobulbs in a plump state.
