Phalaenopsis (Greek, moth-like; suggested by the large white flowers of some species). Orchidaceae. This genus, called by Lindley the grandest of all orchids," contains some of the most useful species to be found in the orchid family; warmhouse.
Of monopodial growth, having short sts. which increase slowly in length: lvs. few, thick, leathery, often mottled: infl. a raceme or panicle, large or not longer than the lvs.; sepals spreading, the lateral ones more or less united with the base of the column; petals about as large as the sepals or very much broader; labellum variously shaped but united with the base of the column.— About 50 species natives of the hot regions of India and the Malay Archipelago, growing on trunks of trees and sides of rocks under conditions of high temperature and great moisture. The fls. are remarkably beautiful in form and color. Those of the larger species are borne in graceful drooping panicles on which they usually all face in one direction.
As all phalaenopsis are natives of the most tropical regions of the globe, it is essential that they be well supplied with heat and moisture, particularly during the growing season, from March to October. Care should be taken to avoid direct draught on the plants, but air should be admitted on all possible occasions. This is absolutely necessary to keep the plants in perfect condition. During bright sunshine the plants should be shaded, but given all the light possible to insure good tough ripe foliage by autumn, and large branching flower-spikes may be expected in the flowering season. A close moist atmosphere will grow large soft foliage, but small flower-spikes usually result. Plants may be grown suspended from the roof, not too near the glass, or on benches, in pots, in baskets, in pans, or on blocks or rafts. They are somewhat whimsical, and once a house is found in which they succeed, they should not be moved. During the growing season the temperature should be kept as uniformly as possible between 70° and 75° F., allowing a rise of 10° with sun heat. The minimum night temperature, in winter, should be 60° to 65° F. Good and ample drainage is absolutely necessary, clean potsherds and lumps of charcoal being the best material, and only sufficient peat fiber and sphagnum in equal proportions should be used to keep the plant firmly in position, as the roots will eventually cover the receptacle in which they are growing. When potting, always give the plant its natural inclination, which is invariably sufficient to prevent water remaining in the axils of the leaves, a condition which should be carefully guarded against, either from watering or from drip. Always keep the plant well raised, when potting, to insure quick and perfect drainage. Sponging the leaves occasionally will keep the plants clean and prevent the attack of thrip and red-spider. The propagation of phalaenopsis is a very slow process, as the plants rarely afford opportunity for division. Sometimes young plants form on the old flower-stems, and these should be left until they make root, at which stage they may be removed, potted, and carefully watered until root-action begins in the new material.
