Our drawing was taken from the specimen above alluded to before it was exhibited in Edinburgh. That plant is now in the possession of J. Buchanan, Esq., Oswald Road, Edinburgh, in whose honour it has been named. Mr. Buchanan is a great admirer of good Orchids, and is forming a nice collection, in which are already included some rare species.
_Cattleya crispa Buchananiana_ is of the same habit of growth as the type, and has dark evergreen foliage and large flowers, which stand out boldly from each other. The sepals and broader petals are of a blush white; the lip large, of the richest crimson, and more crisped at the edge than in most of the species. It produces from four to seven flowers on the spike during the months of August and September, and continues for two or three weeks in full beauty.
Our present subject is a free-growing plant, and thrives under the same treatment as _Lælia purpurata_, being very much like it in its habit of growth. The requisite material in which to cultivate it is good fibrous peat, accompanied by ample drainage, as it requires a moderate amount of moisture, when in vigorous growth, which is during the winter season; of course at that time of year the soil does not dry so rapidly, and therefore water given twice in the week will usually supply all the wants of the plants, but should the weather be very bright, more might be required. This plant makes its growth in autumn and winter, and therefore must be kept as near the light as possible, which will induce greater vigour, and the flowers will be produced more freely. The burning rays of the sun must be kept from the foliage by means of moderate shading.
This, like other Cattleyas, is subject to the attacks of insects, which must be well sought after, so as to be dislodged before they get too strongly entrenched upon the plant. White scale quickly disfigures the leaves if allowed to remain. Moreover, the thrips will sometimes attack the young growth, and should be destroyed by syringing.
This species is easily propagated by dividing the bulbs, leaving several to each piece. This should be done when the plants are starting into growth. After this they must be kept shaded until they make fresh roots in the new soil. A plant should never be divided unless it is in vigorous health, for otherwise the experiment will probably fail.
