THE ORCHID WORLD. 
Vol.1. JANUARY, 1911. No. 4, 
NOTES. 
A new hybrid orchid between Spiranthes 
aestivalis and S. autumnahs is described by 
Hans Fleischmann in the December number 
of the Osterreichische Botanische Zeitschrift.

The Bolanical Magazine (t. 8352) gives a 
figure of Dendrobium Dartoisianum. This 
Dendrobium was discovered in 1905 in Indo- 
China, about 1,750 feet above sea level, and 
was introduced by Mr. G. Bronckart. Its 
nearest ally is D. tortile. The plant from 
which the figure was prepared was purchased 
for the Kew collection in igo6 from Mr. M. 
Verdonck, Ghent. It has been grown and 
flowered in a tropical house at Kew under the 
conditions suitable for the species of the 
group to which D. nobile belongs. During 
winter it is rested in an airy greenhouse.

Mr. J. Smith, orchid-grower to R. Brooman- 
White, Esq., Arddarroch, sends us a flower of 
a splendid variety of Odontoglossum crispum 
named Mont Blanc. The total width is 3! 
inches, and the petals are ij inches in width. 
With the exception of a slight spotting on 
the lip the flower is almost pure white, only 
a faint streak of colour being visible on the 
back of the sepals. It is a true Pacho type 
crispum of the very best class, now so rarely 
seen. Mr. Smith also sends a flower of 
Cypripedium insigne Sanderae and of insigne 
Gladys. The dorsal sepal of the latter differs 
VOL. I. 
from Sanderae in being entirely without spots, 
and, although somewhat broader, it does not 
display quite so much white. 
The Gardener's Chronicle of December 
24th, 19 10, contains an excellent reproduction 
of Polystachya paniculata. It is a native of 
Uganda, and was first imported by Sir Trevor 
Lawrence, Bart., K.C.V.O. The same issue 
also contains a full-page illustration of the 
new Brassia Forgetiana, which was exhibited 
by Messrs. Sander and Sons at the meeting 
of the Royal Horticultural Society held on 
December 6th last, when it received a 
Botanical Certificate.

A curious flower has just opened on a large 
plant of Cypripedium Harrisianum in the 
collection of Mr. Alva J. Hall, Harrogate, 
Yorks. As regards form the flower is normal, 
but in colour it suggests the combination of 
half an albino variety with half an ordinary 
one. From the apex of the dorsal sepal to 
the end of the pouch, including one lateral 
petal and half the column, a clear line may 
be traced dividing the coloured portion from 
the light green or albino part The corre- 
sponding part of the ovary is similarly 
marked, and a greenish-white streak may be 
traced from this organ to the base of the 
flower-spike. The other flowers on this plant 
are normal, both in shape and colour.
