296 THE ORCHID REVIEW. (OCTOBER, 1910. 
DENDROBIUM VEXANS. 
TuHE history of the plant recently identified with the long-lost Callista 
amabilis, Lour., has already been given (pp. 99, 242), and we hoped that its 
identification with Dendrobium hercoglossum, Rchb. f., had settled the 
matter. It is, however, now described by Prof. Dr. Udo Dammer as a new 
species, under the name of Dendrobium vexans, also as belonging to a new 
genus or a new section of Dendrobium, under the name of Goldschmidtia, 
‘‘Goldschmidtia U.D., gen. nov. vel. sect. nov. generis Dendrobium” 
(Orchis, iv. pp. 86, 87, with fig.). The characters relied upon for its 
separation from Dendrobium are common to the species of an anomalous 
little group, which includes D. aduncum, Wall., D. linguella, Rchb. f,, 
and D. hercoglossum, Rchb. f., and all must come under Goldschmidtia, 
whatever its subsequent history may be. The chief differences reside in the 
peculiar saccate base of the lip, and its appendages, together with a slight 
modification in the shape of the mentum, which is a very variable character 
in Dendrobium. D.aduncum isa well known North Indian species, which 
is figured in the Botanical Register (1846, t. 15). D..linguella is only known 
from the original description. It was introduced from the Malay Archi- 
pelago by Messrs.. James Veitch & Sons, and is said to differ from D. 
aduncum in its double lamellar appendages at the base of the lip. D. 
hercoglossum was described from a plant which flowered with Messrs. 
Sander, and is said to have been sent from Malacca by Forstermann. A 
.Chinese plant figured in the Botanical Magazine (t. 6784) was subsequently 
identified with it, and its geographical is not very exactly known.

ORCHIDS BY COLOUR PHOTOGRAPHY. 
Mr. CHAMBERLAIN’S ORCHIDS.—Mr. W. T. Clarke, of Redditch, says 
a Birmingham newspaper, secured severa] good photographs by the direct 
-autochrome process on Whit-Monday, at Highbury, of the Right. Hon. 
Joseph Chamberlain’s splendid Orchids in the flowering house. By quite 
a coincidence the identical blooms were cut and utilised the next day to 
compose the magnificent wreath despatched, by a special messenger, by 
Mr. and Mrs. Joseph Chamberlain to Windsor. The facts were brought by 
Mr. Clarke to the notice of Lord Knollys and Sir Arthur Bigge, and he was 
promptly authorised to forward photographs to Buckingham Palace for 
He Majesty Queen Alexandra, and to Marlborough House for His Majesty 
King George V. respectively. Both Mr. and Mrs. Chamberlain inspected 
the photographs prior to posting, and declared them to be marvellously 
true to Nature, and also expressed pleasure at Mr. Clarke’s idea in ssa 
them to their Majesties.—Journal of Horticulture.
