The Odontoglossum house is fitted with top, end, and bottom ventilators, 
and for shading in summer we use a mixture of flour and whiting on the 
glass, as well as calico blinds. 
I read Dr. Miles Johnston’s article on Cypripediums, and several plants 
I have had from him were exceedingly well-grown. His treatment of C. 
bellatulum, concolor Sander, and Charlesworthii is well worth copying.

NOMENCLATURE OF MULTIGENERIC ORCHID HYBRIDS. 
THE last issue of the Journal of the Royal Horticultural Society (pp. 405— 
408) contains the report of the Committee appointed to consider the 
question of the nomenclature of multigeneric Orchid hybrids, from which 
the following is condensed. 
The question of the nomenclature of horticultural varieties and of 
hybrids of garden plants has been a vexed one for many years, and perhaps 
particularly so in relation to Orchids. In view of the fact that the raising of 
hybrid Orchids connecting many genera is now probable, . . . the Orchid 
Committee of the Royal Horticultural Society considered that the time had 
arrived when some definite system of nomenclature, which should be at 
once simple, euphonious, and distinctive, should be adopted, internationally 
if possible. The Council therefore appointed a Committee to consider the 
question, consisting of Msssrs. J. Gurney Fowler (Chairman), N, C. Cookson, 
de Barri Crawshay, J, O’Brien, H. J. Veitch, Dr. A. B. Rendle, E. A. Bowles, 
W. Fawcett, C. C. Hurst, R. A. Rolfe, and F. J. Chittenden (Secretary), 
Several meetings were held, and a preliminary report was drawn up and 
sent to well-known botanists and Orchid specialists all over the world, and 
after their replies had been considered the following recommendations were 
submitted to the Council :— 
1. The name of every Orchid hybrid should consist of two parts, viz., 
a generic and a specific name, as at present. 
2. The existing bigeneric and trigeneric combinations used as generic 
names should be maintained. It is desirable that these names should be 
written without hyphens. 
Future generic names of hybrids combining two genera should be 
formed by combining parts of the names of the genera combined in the 
hybrid. 
4. Future multigeneric hybrids (combining three or more genera) should 
be given a purely conventional name consisting of the name of some person 
eminent as a student or grower of Orchids, terminated by the suffix “ ara.

A separate generic name should be coined for each distinct 
combination of genera. Thus, Brassocattleya XX Epilzlia, Brasso- 
epidendrum X Lzeliocattleya, and Brassolelia x Epicattleya would all be
