THE ORCHID REVIEW. 149 
I have not mentioned the sports — D. nobile Cooksoni and D. nobile 
Tollianum—as they are so distinct that no one can mistake them. Nor 
have I thought it necessary to describe old varieties like Wallichianum and 
coerulescens; indeed, with the many now like them they are scarcely distinct 
enough to be noticed. The various forms of giganteum are very beautiful, 
but it remains to be seen whether they will remain true in size; some of 
them may probably hereafter deserve a distinct name. 
The above, I hope, may be of use to growers, but I by no means claim 
for these notes that they are perfect or complete, probably there are other 
varieties with which I am unacquainted, which ought to have been 
included.

We have also received several of the above varieties from Mr. Cypher, 
and from W. S. McMillan, Esq., of ‘ Ardenholm,’’ Maghull, Cheshire. 
With respect to D. n. Cypheri we may add that the flower sent by 
Mr. Cypher is not D. n. albiflorum, as the note at page 106 would imply, 
and the question is whether the flower formerly received was authentic. 
We are not sure whether the characters of this variety have been previously 
recorded. The true D. n. albiflorum is well figured at page 113 of our last 
volume. D. n. intermedium, from the description, must be very similar, and 
we should like to see a flower. D. n. nobilius, D. n. Sanderianum, and 
D. n. Cooksoni are also figured on the page just mentioned, together with 
what fairly represents the typical form. The two dark forms have not come 
out very well, but their relative size and shape shows them to be very 
distinct, though so much alike in colour. The D. n. albiflorum described 
above seems to be a finer thing than the form we figured, and may be nearer 
D. n. Amesiz. 
It may be interesting to add a few notes on other described varieties, so 
as to make this account as complete as possible, for the subject is one of 
universal interest, and we have frequently received flowers with requests for 
names, and, like others, have felt the need of a connected account of 
existing varieties. 
The species was originally introduced from South China, and flowered 
with Messrs. Loddiges in 1837, but soon afterwards plants came from the 
Khasia Hills, and now it is known to occur also in Sikkim, Bhotan and 
Tibet, so that it occurs over a rather wide area. The typical form is too 
well known to require description. 
D. N. ca@RULESCENS (Rchb. f. in Walp. Amn. vi., p- 283) has rather 
smaller light rose-purple flowers, and the lip narrower with a more oval 
blade. It was sent to Chatsworth by Gibson in 1837, and flowered soon 
afterwards.—D. ccerulescens, Lindl. Sert. Orch., t. 18.
