This plant requires the same treatment as _C. Skinneri_. It is best grown in a pot or basket, with good fibrous peat and sphagnum moss, the pots being filled three-parts full of drainage, then filled up with rough peat, placing some pieces of charcoal amongst it; this will keep it open and porous, and the roots will run freely among the charcoal. In the growing season the soil requires to be kept rather moist, but the plant does not like too much water about its roots at any time. It is best grown near the light, with a little shade when the sun is hot, the shading not being required at any other time. We find the warm end of the Cattleya house to suit it, as it requires more warmth than some of the other Cattleyas. When the growth is finished in autumn, very little water should be given, and during winter only just sufficient to keep the stems plump, until they begin to throw up their flower spikes in March, when a little more may be supplied to assist the flowers in opening, and to secure finer blossoms. They begin to grow after their flowering season is over, which is the best time for division if it is required, but it is best to avoid cutting this rare plant as much as possible, as sometimes the divided pieces will not succeed so well, especially if the plant is not strong and vigorous. When divided, place them in a shady, moist place until they get established; then they may be removed to a position more exposed to the light. [Illustration: PL. 113. DENDROBIUM WARDIANUM GIGANTEUM.] DENDROBIUM WARDIANUM GIGANTEUM. [Plate 113.] Native of Burmah. Epiphytal. _Stems_ stout, pendulous, deciduous, attaining three feet in length, knotty at the nodes. _Leaves_ oblong-lanceolate, attenuate at the apex. _Racemes_ two or three flowered, issuing from the nodes of the matured stems. _Flowers_ large and conspicuous from their striking colours; _sepals_ oblong-lanceolate, bluntish, white tipped with magenta-rose, the margins reflexed; _petals_ oblong-ovate, obtuse, white more deeply tipped than the sepals; _lip_ cucullate, the base folded over the column, the anterior portion ovate-obtuse, recurved at the tip, entire, the surface covered with crystalline processes, the colour golden yellow at the base with a pair of maroon-crimson spots, the margin and middle portion creamy white, the apex tipped like the petals with deep magenta; _spur_ short. _Column_ short, depressed, almost hidden in the base of the lip, the anther-case white.
