Brassia.—The Brassias are epiphytal Orchids of South America, and may be grown in the intermediate house. The most familiar species are B. brachiata, B. caudata, B. Lawrenceana, and B. verrucosa.
Broughtonia.—B. sanguinea is a pretty, crimson-flowered species from Jamaica. B. lilacina is also a fine species, though rarely seen in gardens. Broughtonias should be grown on bare rafts suspended in the warm or intermediate house.
Brassavola.—A small genus with white, fragrant flowers. B. Digbyana, a species with large, fringed-lipped flowers, has been much used by the hybridist. Brassavolas may be grown with the Cattleyas.
Bulbophyllum.—A widely distributed genus which may be divided into two sections—the deciduous, chiefly Burmese, requiring a dry resting season; and the evergreen, which should not be strictly dried off. All the species thrive in a warm, intermediate house, with cooler rest for the deciduous and highland species. The genus is one of the most varied and remarkable, and full collections of them are grown by some amateurs.
Calanthe.—These are terrestrial Orchids, which may be divided into two sections—the evergreen of the C. veratrifolia class; and the deciduous, comprising C. vestita, C. Veitchii, and numerous other species and hybrids which are extensively grown for flowering in winter. Pot them in a compost of one-half fibrous loam, one-fourth Sphagnum-moss, and one-fourth leaves, with a sprinkling of sand. Rest the deciduous section dry after flowering, and repot them when growth commences in spring. Water liberally with occasional applications of liquid manure, which should be withheld when the growth is completed.
Catasetum.—The Catasetums are curious, epiphytal Orchids, which should be grown in baskets, or Orchid pans, suspended in the intermediate house, and treated in a similar manner to the deciduous Dendrobiums. They require a long, dry rest after the growths are completed. All the species are worthy of cultivation, C. Bungerothii, C. splendens, and C. macrocarpa being the more showy kinds.
Cattleya.—One of the largest, most varied, and florally beautiful genera of Orchids. The plants should be potted as recommended for epiphytal Orchids, and they should be grown in the intermediate house. The C. labiata section, including C. Gaskelliana, C. Mossiæ, C. Mendelii, C. Dowiana and its variety aurea, C Warscewiczii, C. Warneri, and C. Schröderæ in succession, produce flowers for the greater part of the year. C. citrina should be grown in the cool house, suspended from the roof. Cattleyas and Lælias are impatient of a close atmosphere, and therefore the proper ventilation of the house in which they are grown is an important matter. C. Trianæ, var Hydra, is illustrated in [Plate IV].
Chysis.—A small genus of intermediate-house epiphytes, comprising C. bractescens, white; C. aurea and C. lævis, yellow and red; C. Limminghei, and several hybrids.
Cirrhopetalum.—A section of Bulbophyllum, of similar habit, and requiring similar treatment. The curiously formed flowers frequently have the upper segments fringed, and the lateral ones approached and continued into slender tails.
Cirrhæa.—Allied to Gongora, and requiring similar treatment.
