BURLINGTON I A

(named after the "amiable and accomplished" Counte of Burlington). O RD. Orchideæ. A small genus of epiphytal orchids, all of which are beautiful and eminently well worth growing. They may be grown upon small blocks of wood, or in rustic baskets, suspended from the roof of the plant stove, where, if liberally treated with water, and a genial moisture in the air during the growing season, very little else will be required to ensure health and vigour. In the dull days of winter, they should be watered le frequently, but the plants must not be allowed to exhibit the slightest signs of distre from drought, or the consequences may be fatal to their health. When fastening these plants to blocks of wood, a little sphagnum should be used, for experience proves that they thrive best when their thin white roots can escape and hang exposed to the air. If growing them in baskets, it is preferable first to fasten them securely upon small pieces of bare cork, then to fill the basket, and finally to cover the whole thinly with a layer of sphagnum.

Generally speaking, this genus is not a difficult one to cultivate; its great enemy is a small white scale, which secretes itself in the sheathing bases of the leaves. Here it rapidly multiplies, to the great detriment of the plants; the leaves soon turn yellow at the base, and drop off; the whole plant looks sickly, and soon dies, or else requires a very long time and much trouble to achieve its recovery to health. To prevent this, the bases of the leaves must be carefully looked into every time the plants are taken down to be dipped in water; and, should the slightest sign of this pest appear, a thorough washing with soft soap and tepid water must be given, repeating the operation every day until all traces of the insect are removed. Red thrip are also apt to work much mischief with these plants. They take up their abode in the same way as the white scale, and if not speedily removed or destroyed, soon make sad havoc. To put a stop to the ravages of this pest, a wash should be given, as before recommended, and after the soap has been rinsed out of the base of the leaf, a little tobacco powder should be sprinkled into the hollows, and allowed to remain for a day or two before brushing it off. This proce will, however, cause a somewhat dirty appearance, but it will ensure ultimate health and vigour. Propagated by dividing the plants.
