Summer (Pseudo-bulbs ft to ft high)

Pseudo-bulbs 1ft. to 3ft. high, and 1/2in. in diameter. From six to eight leaves clothe the upper part of the stem. Assam, 1851. An erect stove evergreen species, best adapted for growing in pots, in a peat soil. (L. & P. F. G. ii. 189).

D. crassinode (thick-knotted).* fl. from the last matured growth, each node producing from two to four stout blossoms; sepals and petals waxy-white, tipped with rich purple; lip white, with an orange blotch at the base. February and March. Pseudo-bulbs 1ft. to 1 1/2ft. long, and 1/2in. in diameter. Burmah, 1868. This species is remarkable for the enormously swollen joints of the stem, which are 1in. in diameter, and arranged about 1in. apart. A pendulous stove deciduous species, best grown in a small basket or on a block of wood. (B. M. 5766.) There are two or three very good varieties, including albiflorum, pure white, with a dark yellow disk; and Barberianum, a great improvement on the type, with more highly-coloured flowers, which are of greater substance, the pseudo-bulbs also are stouter. D. crepidatum (slippered). fl. from the last matured growth, two and three together, about 2in. across, on somewhat long footstalks; sepals and petals white, tipped with pink; lip stained with yellow. March. Pseudo-bulbs 1ft. to 1 1/2ft. long, with white lines running their entire length. Assam. A very handsome drooping greenhouse deciduous species, well suited for growing in a basket or on a block. (B. M. 4993.) D. cretaceum (chalked). fl. chalky-white, solitary from the joints of the long leafless stems, rather small, downy; lip with a pale yellow disk, pencilled with crimson; margin ciliated. May. Pseudo-bulbs 8in. to 14in. long, 1/2in. in diameter. India, 1846. A compact-growing pendulous stove deciduous species. (B. M. 4686.) D. crystallinum (crystalline).* fl. of moderate size, freely produced from the last matured growth; sepals and petals white, tipped with rose or purple; lip orange at the base, tipped with purple. Summer. Pseudo-bulbs 1ft. to 1 1/2ft. long, 1/2in. in diameter. Burmah, 1868. An erect-growing stove deciduous species, allied to D. Bensoniae. (B. M. 6319.) D. cucullatum (hooded). fl. 1 1/2in. to 2in. in diameter, suffused with a pale pink tint; lip pale yellow. India, 1835. Very closely allied to D. Pierardii, from which it is principally distinguished by the lip being more ovate in form and more open at the base, the sides not being rolled round the column to half the extent they are in D. Pierardii, to which, however, the present species is inferior from a horticultural point of view. Greenhouse. (B. M. 2242.) D.cupreum (coppery). A synonym of D. moschatum.

D. Dalhousianum (Lady Dalhousie's).* fl. large, 3in. to 5in. across; sepals and petals buff, shaded with pale lemon; lip of the same colour, spotted at the base with two large blotches of dark crimson, and margined with rosy-pink; racemes drooping, produced from the growth of the previous year, six to ten-flowered. April and May. Pseudo-bulbs stout, erect, 3ft. to 5ft. high, about 1in. in diameter, with purple lines running their entire length. India, 1837. A noble strong-growing stove evergreen species, requiring, however, a considerable space to grow it in anything like perfection. (P. M. B. xi. 145.) D. densiflorum (dense-flowered).* fl. rich clear amber, produced in numerous long dense pendulous racemes, which spring from immediately below the junction of leaf and stem; lip orange, delicately fringed. April and May. Pseudo-bulbs somewhat club-shaped, about 1ft. in height, furnished near the apex with several broad, oblong, deep green, shining leaves. India, 1829. A very handsome free-flowering stove evergreen species. (B. R. 1828.) D. d. albo-luteum (white and yellow). A very floriferous form, differing from the type "in the greener, glossier pseudo-bulbs and leaves, and in the long lax panicle and colourless transparent sepals and petals," which are sometimes tinged with pink; lip wholly orange, or orange-red. Moulmein. SYN. D. thyrsiflorum. (B. M. 5780.) D. d. Schroederi (Schroeder's). This hardly differs from the last-named variety, except in the purer white of the flowers, and the golden labellum gradually shading off towards the margin into a paler yellow. India, 1870. D. Devonianum (Duke of Devonshire's).* fl., sepals and petals soft creamy-white, tinged with pink, the latter in addition being tipped with purplish-magenta; lip white, margined with purple and spotted with rich orange at the base, and bordered all round with a delicate lace-like frill, which gives the plant a charm that is quite unique. Well-grown pseudo-bulbs often carry from ninety to a hundred flowers, which are about 2in. across. March and April. Pseudo-bulbs 1ft. to 3ft. long, 1/2in. in diameter. East Indies, 1837.

Pseudo-bulbs about 2ft. high and 1/2in. in diameter. Moulmein, 1864. An erect, slender-growing, stove deciduous species. (B. M. 5564.) D. Draconis (Draco).* fl. white, moderate-sized, produced from the points of the last matured growths in bunches of six or more; lip with a red base. Pseudo-bulbs 1ft. to 1 1/2ft. high, 1/2in. in diameter. Moulmein, 1862. Erect stove evergreen. SYN. D. eburneum. (B. M. 5459.) D. eburneum (ivory-flowered). A synonym of C. Draconis.

Farmeri (Farmer's).* fl. produced upon long pendulous racemes, in the same manner as those of D. densiflorum, but not so closely set together; sepals and petals pale straw-colour, delicately tinged with pink, whilst the disk of the lip is of a golden-yellow. May. India, 1847. A beautiful and delicate upright-growing stove evergreen species, attaining about 1ft. in height, bearing several shining dark green leaves towards the top of its club-shaped stems, which are swollen at the base into a kind of pseudo-bulb. (B. M. 4659.) D. F. aureoflavum (golden-yellow). A beautiful variety, distinguished from the type by its bright yellow sepals and petals, and golden lip. Moulmein, 1864. (B. M. 5451.)
