150 THE ORCHID REVIEW. 
having tall stems, darker foliage, and flowers richer coloured than in the 
type. A drawing which we have seen much resembles the preceding, 
especially in the shape of the lip. 
D. N. ALBUM (Rchb. f. in G. C., 1884, i., p. 338). Sepals and petals white 
with pallid purple tips; apex of lip very pale purple. Appeared with 
W. Lee; Esq., Leatherhead.—Orchidophile, 1890, p. 304, with plate, fig. 2. 
D. n. AMESI& (Orch. Rev. i., p. 115). A large pure white form with 
large rich maroon disc. It is much finer than D. n. albiflorum, but similar | 
in colour, Appeared with Messrs. F. Sander & Co. in 1893. 
D. N. SCHNEIDERIANUM (Rchb. f. in G. C., 1884, i., p. 577) has a yellow 
hue over the lip, and a dark mauve-purple mark at the base. Appeared 
with Mr. Oscar Schneider, of F allowfield, Manchester. 
D. N. ToLLianum (Rchb. f.inG. C., 1884, 1., p. 445). An abnormal form 
with the pedicels twisted, the flowers appearing inverted and the segments 
not fully expanded. Appeared with Mr. G. Toll, of Manchester, and with 
W. Lee, Esq., of Leatherhead. 
D. n. Cooxsoni (Rchb. f. in G. C., 1885, i., p. 692). Petals having 
a maroon blotch at the base, and less expanded than usual. Appeared with 
Norman C. Cookson, Esq., Wylam-on-Tyne, and shortly afterwards in two 
other collections.—Journ. of Hort., 1890, i., p. 63, fig. 10;. Orch, Rr we 
pp. 113, 115, fig. 15. 
D. N. BURFORDIENSE (Garden and Fovest, 1894, p. 159). Lateral sepals 
with a maroon blotch on the lower half near the base. Appeared with Sir 
Trevor Lawrence, Bart., and with Hicks Arnold, Esq., of New York.— 
D. n. Burford variety, Journ. of Hort., 1899, i., p- 63, fig. 9 sie Se = 
A similar form to the preceding, but with much larger flowers and 
broader rounder segments, appeared with C. of Carpender, Esq., of New 
Brunswick, N. Jersey, in 1889. An exceptionally fine form. 
A rather curious point arises with regard to the plant described by 
Griffith as D. Lindleyanum (Griff. Notul. Pl. Asiat. lii., p. 309). It is an 
unusually large and tichly coloured form from the Khasia Hills, and 
apparently includes D. n. nobilius. For many years all the plants of the 
latter in cultivation had been derived by propagation from the original one, 
but now it has been re-introduced in a form not absolutely identical with 
the original, and a plant which flowered for the first time in the collection _ 
of the late G. Hardy, Esq., in 1889, is still finer. May not this and the. 
so-called D. n. giganteum belong to Griffith’s plant? It appears to bea 
local form of D. nobile. The figure cited by Griffith and a second species 
of the same name (/.c., p. 311) belongs to D. Dalhousieanum. 
Lastly, may be mentioned a very large but lighter coloured form, which 
appeared in the collection of W. W. Lunt, Esq., of Boston, U.S.A., some 
D. nobile, but is distinct from anything we know. _ 
time ago, which we should like to see again. It appears to belong to x
