little shaded until re-established. C. Trianz then follows, and these make 
a grand display when in the pure air of the country. But I am sorry to 
add neither of the two species are suitable for growing in large towns, as 
the flowers coming so early in the season are cut off by smoky fogs, and 
generally before the bud expands, which is most vexing. Cattleya Triane 
flowers from February to April, and is a most variable species. Some 
varieties vie in size and beauty with any of the labiata section, though it is 
true there is a large percentage of inferior varieties among them—larger 
than in any other—consequently good varieties of Trianze should receive 
‘special care, as they are always valuable. I believe there are few true C. 
Trianz alba in existence, though many are sold as such, but most of them 
vary from year to year. As a rule, the better the plant is cultivated and 
the growths matured, the more the colouring matter present in the bloom. 
Cattleya Mendelii and C. Schroedere are the next to open, and these 
last through April and May; and then comes C. Mossi, which lasts 
through June. In July and August C. gigas and C. Gaskelliana are con- 
spicuous. I have previously said that C. gigas and its varieties should be 
grown with the Mexican Orchids, or in some similar place, and stinted with 
water (though not shrivelled) until the new growths are three or four inches 
high. This species, on the whole, is a shy bloomer, and even under this 
treatment miss doing so sometimes. Cattleya Gaskelliana should now be 
potted, or it can be left and done after flowering. I prefer the present time. 
Then comes for September the beautiful Cattleya Dowiana and its variety 
aurea. I find it is best to grow this species warmer than most others 
during the winter months, or the plants will suffer. They are either given 
a place at the warmest part of the Cattleya house, or in another house 
where the temperature averages five degrees higher. And if they are near 
the glass so much the better. I also give this treatment to C. Lawrenceana, 
which flowers in April and May, and this species is best grown during the 
summer with the hot Dendrobium. C. Eldorado is another wanting a little 
xtra warmth in winter, and is grown in summer with the last named, as 
are also C. Lueddemanniana, C. superba, C. Aclandiz, and the new C. Rex. 
For Cattleya Dowiana this extra heat during growth is not so essential, 
and it may be grown at the warmest end of the Cattleya house ; but should 
a plant be late in starting, or in a weak state of health, I recommend that it 
should be grown in heat until it has recovered. 
Cattleya intermedia, Lelia x elegans, and any garden hybrids owing 
parentage to either, are also better for a little more warmth during winter 
than the ordinary Cattleya house affords, as these kinds are then generally 
in active growth. So is Lelia purpurata, but for this more heat is not 
necessary, as it is a more hardy growing species. L. superbiens should be 
grown in the Mexican house. 
Now is a good time to repot Ccelogyne cristata and others that have
