We have found this plant do well at the cool end of the Cattleya house. A cooler situation even than this will do. It must be potted in rough fibrous peat, with good drainage, and must be well elevated above the pot so that its roots can work about the soil. A little charcoal intermixed with the peat helps to keep the soil open; moreover, the roots like to cling to it, and it prevents the material from becoming sour. This plant will also do well in a basket suspended from the roof, as it likes a considerable amount of light to ripen its bulbs and foliage; this causes it to grow stronger and flower more freely. It requires the same treatment as _L. Skinneri_ as regards watering during the growing season, but when at rest must be kept drier. Orchids at Upper Holloway.—We were much gratified, when recently calling at the Victoria Nursery, to see the excellent condition of the Orchids generally, and the fine display of flowers. Some of Mr. Williams’ Orchid houses are provided with a vestibule, which, from its contiguity to the outer atmosphere and the frequently open doorway, is cooler and drier than the growing houses attached, and into these the blooming plants are brought for display, with the result that they are thus kept much longer in a state of beauty. The stock here is large and in first-rate condition, as, indeed, one would expect it to be in the hands of so skilful a grower. The plan of shading adopted in this establishment is much to be commended; the canvas, which is of a special construction, is so fixed that it is kept quite clear of the glass, and a space is thus provided through which the air is constantly passing. In the case of cool Orchids this is of great importance, as it acts so as to moderate any excess of summer heat. We were much pleased to see that Mr. Williams’ large specimen plants, now in flower, are legitimately “grown on” and not “made up” as has lately been much the fashion, a practice which, it may be hoped, the rule now adopted at some exhibitions, to the effect that “made up” plants will disqualify, will put an end to. Many fine species were in bloom, but as the object of this note is not to make a catalogue of them, we will only add that the Cattleyas, Vandas, Odontoglots, and Masdevallias were blooming very freely and were represented by many finely grown specimens.—T.
