luteopurpureum.” It was compared with a middle-sized O. Pescatorei, the 
colour of the flowers being light whitish sulphur, blotched with cinnamon. 
The toothed petals and column-wings, together with the shape and crest of 
the lip, all show characters derived from O. luteopurpureum. The plant 
exhibited at a meeting of the Royal Horticultural Society on April 22nd, 
1890, by H. M. Pollett, Esq., under the name of O. sceptrum album, is a 
form of O. x Horsmanii. 
O. x lyroglossum was described in 1882, from an unknown English 
source, as “apparently a natural hybrid between O. nobile (Pescatorei) and 
O. luteopurpureum,” and the description and figure subsequently published 
leave no room for doubt on the matter. It afterwards appeared with Dr. 
Wallace and others. 
QO. x brachypterum appeared in the establishment of Messrs. James 
Veitch and Sons, of Chelsea, in 1882. Reichenbach remarked, “ It is quite 
like O. x Horsmanii, but has not the lamelle on the lip which are found 
in O. Pescatorei.” The flowers are light yellow, with a few cinnamon 
blotches. Reichenbach thought O. Lindleyanum might be one parent, but 
the broad segments, the shape and crest of the lip, and toothed column- 
wings all indicate rather O. luteopurpureum. O. x Kalbreyeri is mentioned 
at the same time, but I cannot find that it has ever been described, and 
nothing more seems to be known about it. 
O. x ferrugineum appeared in the collection of Mr. E. Harvey, of 
Aigburth, Liverpool, in 1883. The sepals and petals are described as dark 
cinnamon, with yellow tips, the petals toothed, and the front of the lip 
dilatate, fimbriate, and whitish yellow, with a brown spot on the disc. 
O. luteopurpureum was clearly one parent, while the crest of the lip and 
column-wings suggest O. Pescatorei as the other. This, too, seems to have 
been lost sight of. 
O. X majesticum appeared in the collection of M. Charles Vuylsteke, of 
Loochristi, Ghent, in 1891, and received a Certificate of Merit at the Ghent 
meeting in June. It is a very fine variety of O. x Horsmanii. :

ODONTOGLOssUM LINDLEYANO-NOBILE.—This hybrid originally appeared 
in 1887, in the establishment of Messrs. F. Sander and Co., of St. Albans, 
and subsequently in other collections. It has many of the characters of 
O. Lindleyanum, but in the shape of the lip it approaches nearer to the
