of genera. Thus all combinations of the four genera, Brassavola, Cattleya, 
Lelia and Epidendrum, whatever the order in which they are combined, 
should receive the same generic name, which might be, for example, 
Linneara. 
As exceptions, the names of the trigeneric hybrids Brassocattlelia and 
Sophrocattlelia, which are already in use, should be retained. 
Article 15.—For a new hybrid to be considered as published it must be 
named according to the rules, and a formula and description should be 
published. 
Publication should be made in the same way as provided for horti- 
cultural varieties, as given in articles 5 and 6. 
Article 16.—In all cases where the rules of horticultural nomenclature 
would be contrary to accepted custom, they should not have a retroactive 
effect.

CooL. House. 
THE treatment required by all plants in this house will be much the same 
as that advised in my last month’s article. On bright days it will be well 
to look over the Orchids daily, to see that none which are in full growth 
become at all dry. Extra ventilation and shading will be needed, keeping 
the blinds down till the sun is well off the house. On warm nights a little 
bottom air can be admitted, and fire heat may now occasionally be dispensed 
with. There should still be several Orchids which need repotting or top- 
dressing, and this should be done immediately, as it is not advisable to 
disturb any plant during the hot weather. Damping is needed three times a 
day, in the morning and evening and about mid-day. On dull and cloudy 
days twice, however, will be sufficient. If the atmospheric conditions are 
properly regulated the plants will make rapid progress. 
CaTTLEYA HOUSE. 
Here a little shade is needed in the middle of the day, but only keep it 
on while the sun is shining directly on the plants. Damp down at least 
three times a day, spraying the plants overhead about four o’clock. All 
growing and flowering Cattleyas, Lzlias, and their hybrids must be kept 
well supplied with water. The repotting of these Orchids, and also of 
Dendrobiums, can be proceeded with as soon as any plants are ready. The 
imported plants of Vanda ccerulea are now rooting freely, and those of the 
earlier importation should be provided with suitable compost. Remove a few 
of the crocks, and for soil use a mixture of one part polypodium and osmunda 
fibres to two parts of pure green sphagnum moss.. These should be chopped 
up finely and used in a damp, not wet, condition. The supply of water
