the remarks. As it is, there is just the danger that P. veratrifolius may be 
confounded with the Calanthe of the same name. 
The worst of it all is that genera may no longer be based on well- 
marked structural similarities and differences, but must be taken, red-hot, 
as it were, from the hands of the hybridist. We are evidently on the eve 
of some startling developments, and we believe hybridists have the ‘“ re- 
vision ”’"—we suppose this will now be the correct word—of two or three 
other genera in progress. 
Why draw the line at genera? It might simplify matters still further if 
species were included. We might then show that nearly all the tropical 
Cypripediums were varieties of one variable and widely diffused species, 
which would save a lot of trouble. We merely offer the suggestion. 
THE HISTORY OF ORCHID HYBRIDISATION. 
PaRT III. 
(Continued from page 40.) 
Our last paper brought us down to the end of 1876, during which year con- 
siderable progress was made. In 1877 less than half as many novelties 
appeared. The first, however, was the work of a new operator. 
Zygopetalum x Clayi was raised in the collection of Colonel Clay, of The 
Slopes, Wallassy, Birkenhead. Its parents were Z. crinitum and Z. 
maxillare, the latter, I believe, being the pollen parent. It made its début 
in the Manchester Botanical and Horticultural Society on April 27, 1877, 
and was awarded a First-class Certificate. Soon afterwards it was described 
by Reichenbach. 
Selenipedium x albopurpureum, which next appeared, was the first 
Secondary hybrid in the genus. It was obtained by Mr. Seden, by crossing 
S. Schlimii with the pollen of S. x Dominyanum. It was described as a 
teat curiosity, the father parent being itself a mule, which had flowered for 
the first time about seven years before. It is a very beautiful thing, showing 
a curious combination of the characters of the three parent species; S. 
Schlimii, however, obtaining a preponderating influence in the matter of 
.- ©olour, as is usually the case. 
Lelia x Sedeni, obtained by crossing Cattleya superba with the pollen of 
Lelia x devoniensis, flowered for the first time during 1877. It is said to 
combine the free growth of the pollen parent with the brilliancy of colour 
and fragrance of the seed-bearer. A single plant only was raised, which is 
now in the collection of Baron Sir Henry Schréder, at The Dell, Egham.
