The plants are best grown in baskets or pans suspended from the roof, where they get all the light, but just keeping them from the burning sun. We find rough fibrous peat with sphagnum moss and good drainage to suit them. They must be kept moist at the roots during the growing season, but when their growth is completed only just sufficient to keep the stems plump must be allowed them until they begin to show their flower buds: then give a little moisture at the roots, which will induce them to bloom finer, and to start into growth after their flowers are over. Sometimes they will start growing during the blooming season, and if so this should not be checked. We find the East India house the most suitable one for them, or they will grow in any house where the heat is kept up during the growing season. When at rest less warmth will suffice. They must be kept free from insects. Sometimes the red spider and thrips will attack the leaves, but these may be kept under by syringing or using tobacco-smoke—the latter sparingly, as too much will be very injurious to the young growths. Cattleya Trianæ formosa (Plate 108).—In the remarks on this Cattleya, instead of “the lip rich rose-magenta being beautifully frilled and edged with a lighter tint of the same colour. The flowers, which are two and a quarter inches in diameter, have the throat orange veined with a deeper orange, and are produced,” &c., read “the lip rich rose-magenta being beautifully frilled and edged with a lighter tint of the same colour, two and a quarter inches in diameter, the throat orange veined with deeper orange. The flowers are produced,” &c., &c. [Illustration: PL. 114. TRICHOSMA SUAVIS.] TRICHOSMA SUAVIS. [Plate 114.] Native of the Khasya Mountains. Epiphytal. _Stems_ thin, terete, tufted, from a short rhizome, with a few sheathing verrucose scales at the base, the apex diphyllous. _Leaves_ somewhat fleshy, broadly lanceolate acuminate, obsoletely three-nerved, the base contracted into a sheathing petiole. _Flowers_ in short terminal racemes, fragrant; _sepals_ lanceolate, spreading, the dorsal one free, the lateral ones somewhat broader, adnate at the base with the foot of the column, so as to form a short chin, creamy white; _petals_ erect, lanceolate, resembling the dorsal sepal, creamy white; _lip_ articulated with the foot of the column, with a short incumbent claw, the limb three-lobed, the side lobes plane striped with brownish crimson, the middle one undulated, yellow spotted with red and bearing five crispy lamellæ or crests, there being also four such crests on the disk. _Column_ short, semiterete, marginate, the anther-bell irregularly toothed at the edge, the anthers incumbent affixed within the margin. _Pollen-masses_ eight.
