304 THE ORCHID REVIEW. | OCTOBER, 1910+ 
supply of water until the spikes are over. They are a beautiful sight to 
see when well flowered, flowering as they do during the dullest time of the 
year, and the flowers last such a long time in perfection. They should be 
kept well sprayed.until the flowers are open, to keep off red spider, but not 
heavy enough for the water to lodge in the base of the leaves. 
CYPERORCHIS.—C. elegans with its distinct straw-coloured flowers is. 
now in flower, and C. Mastersii with its white flowers prettily spotted 
with purple which will follow in a few weeks. They are not often seen 
at their best. They are closely allied to Cymbidiums, and quite as easy to 
grow if they are given the same treatment. 
DENDROBIUMS. — Among Dendrobiums now fast completing their 
growths for the season, and requiring a cooler temperature to fully harden 
them up are, D. aureum, Findlayanum, crassinode, nobile, tortile, X 
Dominianum, xX _ Ainsworthii, and its varieties, Leechianum and 
splendidissimum, with a host of other hybrids now in cultivation. The 
grower must use his own judgment, by finding out the parentage of each 
one he happens to have in his collection, and treating them accordingly. 
The above named will rest well in a temperature of 53° to 55°. The ever- 
green kinds, D. densiflorum,  thrysiflorum, Farmeri, pulchellum 
(Dalhousieanum), fimbriatum, chrysotoxum, and suavissimum, as they 
finish making up their bulbs, must also be given cooler quarters, but will 
not stand so cool a temperature as the preceding group. The Cattleya 
house is the best place to rest this section of Dendrobiums, as the leaves 
do not get spotted if carefully watered, and it is almost impossible to 
avoid the disfigurement if they are given too cool a temperature. 
D. WarpiANuM will also be ready for removal, and this species will 
stand more cold, when at rest, than any of the warm-growing kinds. 
This species flowers much better if rested in a temperature of 43° to 45° 
after the bulbs are fully matured. A good place to rest them is in an 
ordinary cool conservatory, where they get. plenty of light and air. The 
young growths commence to push very early, and it is quite natural for 
them to do so, as they are seldom quite dormant for long. The flower 
buds also push very early, but these things should not tempt the grower 
to increase the warmth or the supply of water. The middle of March is 
quite early enough for them to be in flower, and early in April is early 
enough to place them in their growing quarters, and by doing so the 
plants do not deteriorate, but increase in vigour. D. Parishii, Bensoni, 
Lowil, aggregatum, macrophyllum, MacCarthiz, and D. Phalenopsis are 
best left in the warmest house, as coming from warmer regions they 
require more heat to keep them in good health. The supply of water 
should gradually be reduced until only sufficient is given them to keep the 
bulbs plump.
