A MEETING and house dinner of the Horticultural Club was held at 
the Hotel Windsor, Victoria Street, Westminster, on November 
17th, under the Presidency of Sir Harry J. Veitch, when the subject of the 
lecture was ‘‘Some Results of Orchid Hybridisation,” by Mr. H. J. 
Chapman, Oakwood Gardens, Wylam, who illustrated his remarks by a 
large number of autochrome and hand-coloured lantern slides. The 
lecturer referred to the remarkable results obtained by Orchid hybridists 
especially in the intercrossing of allied genera, which had resulted in a 
great progressive development that was particularly evident in the great 
variety of Orchids now obtainable in flower during the winter months. 
Commencing with the genus Phaius, the lecturer showed flowers of the 
species which have been so successfully crossed at Oakwood, with the 
resulting hybrids, including a few well-grown specimens in. which 
the colouring was remarkably well shown. He then passed on to Odonto- 
glossums and showed a remarkable series of blotched hybrids, including a 
number of the most diverse seedlings obtained from the same capsule; in 
the case of the secondary hybrid O. percultum the same pod had produced 
every intermediate form from white to solid purple. A large series of 
Slides was shown, of both the original species and the primary and 
secondary hybrids, including a number of plants in flower, in which some 
tealistic effects were obtained, especially in groups intermixed with the 
scarlet Odontiodas, which have now attained such a marvellous develop- 
ment under the hands of the hybridist. 
Passing to the Cypripedium group, Mr. Chapman showed some of the 
Popular species and hybrids of both the Old World and the American 
Cypripedes, and also a transverse section of the ovary in each to show 
the essential distinctness in structure. Showing a good slide of C. insigne 
. Sander, the lecturer remarked that it had several times been raised true 
from seed when self-fertilised, but when crossed with so-called albinos of 
Other species it invariably reverted to ordinary coloured forms. This.
