88 THE ORCHID REVIEW. 
one which actually increases in size year by year, is grown in the tempera- 
ture of a greenhouse the whole year round on the stem of a living tree- 
fern, and naturally shaded by its large fronds. The beautiful D. Falconeri 
giganteum is best grown in the Intermediate house. 
Most other species of Dendrobium, however, require strong heat, 
light, and an abundance of moisture when growing, but when at rest it 
becomes again necessary for them to part company, some being better 
suited in one temperature and some in another. But as the resting season 
is now nearly over and new growth about to commence, this point may 
be left for the present. Suffice it to say, that on the character of the rest 
given the behaviour of the plants during the forthcoming season of growth 
largely depends. 
The house where Dendrobes are grown should be rather a lofty 
structure, so that the plants may occupy positions high up near the glass, 
where the warm, moist air can freely circulate round about them. The 
possibility of the young new growths damping off is then at a minimum. 
I have never seen Dendrobes grow really satisfactorily in a low-built 
structure; the atmosphere must be as lively and buoyant as possible, and 
this is more likely to occur in the former than in the latter house. The 
many lovely varieties of D. nobile (still one of the best) and the many 
beautiful hybrids owning it as a parent, are now making a grand display ; 
also the sweet-scented D. aureum, the delicate D. Findleyanum, the 
stately D. Wardianum, D. crassinode, and their various hybrids. After 
the flowering period is past, a genial temperature of between 60° and 70° 
is warm enough until the days lengthen and the sun’s rays become more 
powerful, and then a hot moist temperature is most advantageous. 
There are other genera of Orchids sometimes spoken of as intermediate, 
but which really require hot treatment during the growing season, and no 
better place can be found for the following than alongside the Dendrobiums, 
suspended near the glass—in fact, the same cultural conditions, both while 
growing and at rest, is advisable. These include the following : Stanhopeas, 
Catasetums, Mormodes, Cycnoches, Chysis, Coryanthes, Gongoras, Schom- 
burgkias, Galeandras, Cyrtopodiums, and Spathoglottis. A very pretty 
species of the last named is S. Viellardii (Angustorum), whuse lovely 
flowers are of a dark, bright rose colour, and produced on a tall spike, in a 
cluster of ten to fifteen, from October to January. As the first flowers fade 
and pass away, new ones continually take their place. It should be grown, 
as above mentioned, in pans or baskets. 
A pretty Orchid in bloom just now is Aganisia ccerulea. It is well 
worth growing, and succeeds best in a sunny position in the Dendrobium 
house. On the other hand, a shady position in the same house is most 
suitable for Paphinia grandis, a very curious and sweet-scented species 
now bleoming, both of which should be kept in the warmest house during
