Epiphytal. _Stems_ (pseudobulbs) club-shaped, furrowed in age, about eight to ten inches in height, monophyllous. _Leaves_ oblong-ligulate acute, leathery and rigid in texture, dark green, growing to about ten inches in length. _Scape_ emerging from an oblong pale green compressed bluntish bract or spathe, about four-flowered, the racemes erect. _Flowers_ rather large, measuring upwards of four inches in each direction without being spread out; _sepals_ lanceolate, reflexed and much twisted, of a pleasing nankin or fawn colour; _petals_ somewhat broader than the sepals, also convex and curled, finely toothed at the edge, of the same colour as the sepals; _lip_ three-lobed, the lateral lobes rolled over the column at the base, spreading in front, where they are beautifully veined with magenta-rose, the middle lobe rounded with an apiculus, prettily crispate-undulate, creamy white pencilled over but more sparingly than the side lobes with delicate magenta lines; thus the whole surface of the lip is radiately venose with magenta-rose. _Column_ club-shaped, concealed by the infolding of the lateral lobes of the lip. Lælia grandis, _Lindley_, in _Paxton’s Flower Garden_, i., 60, fig. 38; _Id._, _Gardeners’ Chronicle_, 1864, 1202; _Flore de Serres_, vii., 238, woodcut; _Id._, xxiii., 297, t. 2473; _Hooker fil._, _Botanical Magazine_, t. 5553; _Regel_, _Gartenflora_, t. 698; _Williams_, _Orchid Grower’s Manual_, ed. 5, 205. Bletia grandis, _Reichenbach fil._, in _Walpers’ Annales Botanices Systematicæ_, vi., 424. We have now the satisfaction of submitting to our readers an illustration of a very distinct plant, one that is little known, and which is extremely rare. The flowers are most remarkable in the singular colour of the sepals and petals, and in the chaste and prettily marked lip or labellum. _Lælia xanthina_ is often sold for this plant, which it much resembles in growth, but the flowers are totally different, as may be seen by a comparison of our present plate with the figure of the true _L. xanthina_, published in the first volume of the _Orchid Album_ (Plate 23). This comparison will show that the two species are quite distinct in the form of their flowers, as well as in the colour and markings of the lip. We are indebted for the opportunity of figuring it to Baron Schröder, of The Dell, Staines, in whose fine collection it bloomed in June last, and was very much admired by those who saw it. _Lælia grandis_ is an evergreen plant, with the stems or pseudobulbs about eight inches in height, and supporting a dark green leaf about ten inches in length. The flowers are produced several together from a sheath at the apex of the stems; the sepals and petals are nankin-yellow, the lip cream-coloured distinctly veined over the interior surface with rose colour. The plant blooms in May and June, and the flowers last in beauty for two or three weeks.
