These names seem to me to be well adapted to the purpose for which 
they were chosen, though 1 think Epivola would have been preferable to 
Brassoepidendrum, both on grounds of precedent and euphony. In 
two cases the progeny is the result of crossing a generic hybrid with a 
third genus, and the Scientific Committee suggest that to these a purely 
conventional name should be assigned, preferably with a distinctive 
termination. But Brassocatlelia and Sophrocatlelia may be called 
conventional names which have the additional merit of being descriptive, 
and should other cases occur it may be possible to coin equally happy 
appellations. At all events let us avoid any prohibitory enactment. And it 
should not be forgotten that Brassocatlelia may include hybrids between 
Brassocattleya and Lelia, Brassolelia and Cattleya, Brassavola and Leelio- 
cattleya, Brassocattleya and Brassolelia, Brassocattleya and Leliocattleya, 
Brassolelia and Leliocattleya, hybrids of Brassocatlelia crossed by itself, 
in fact every possible combination between the three genera. Similar 
remarks apply to Sophrocatlelia. Conventional names that are not 
descriptive may yet be necessary, but they can scarcely be improvements, so 
let us not anticipate the evil day. It is quite possible that hybrids will 
yet be produced combining four or even five genera— the successful union 
of Epiphronitis with Brassocatlelia would give us the latter—but the raiser 
should be able to call it what he likes, always provided that the name is in 
accordance with the rules of generic nomenclature. For the present 
hybrid the name Diacattleya is here adopted, in harmony with Dialzlia, 
and under this name it was recorded in two of the reports of the meeting, 
though in other cases Diacrocattleya is given.

SHADING.—One of the mast important parts of Orchid culture is to have 
light without the direct rays of the sun reaching the plant. We have tried 
all sorts of blinds and find the lath roller blinds suit our purpose the best, 
as they give a satisfactory shade from sun, and they are also of great 
benefit as a protection from frost in the winter months. We find that by 
using them it makes a great difference to our coal bill, and keeps the 
temperatures even. 
We do not use ropes and pulleys, as 
weather, for when they get frozen the blinds canno 
always snapping. Qur blinds are fixed on the houses 
of up and down the roof. They are made in four and 
the runners are I by 14 inches in section, made of pitch 
they are a nuisance in frosty 
t be used, and ropes are 
to roll sideways, instead
