THE ORCHID REVIEW. 109» 
sufficient moisture only should be given to prevent shrivelling. I strongly 
advise giving plants water immediately they show signs of shrivelling, as 
I have no doubt they are sometimes weakened and almost killed by too: 
much drought in winter. 
“T also advise wintering the choice hybrids in a fairly warm house, never 
falling below 55°. Such varieties as D. Bensone, aureum, lituiflorum, and 
all the Australian and New Guinea Dendrobes, should never be placed 
in a cool house, but must be kept warm and dry during the resting period.. 
The Australian ones when retaining their foliage always make better and. 
stronger growths than if allowed to lose their leaves. 
‘1. Dearii should never be kept dry, nor placed in a cool house, as it: 
appears to grow and flower all the year round, and should therefore be kept 
moist. D. formosum requires plenty of heat and moisture during the 
growing season, and well repays the grower by producing its splendid 
blooms during autumn, when white Orchids are scarce. D. infundibulum. 
and Jamesianum should be grown cool and moist during summer, and in. 
autumn placed at the cool end of the Cattleya house, and kept moist, in 
order to mature their growths, when they produce flower buds in the spring.. 
“‘D. Bensonz is considered a very difficult plant to cultivate for many — 
years. But I have grownit for eight years and at the end of that period. 
had finer bulbs than those imported. I believe many, or nearly all, are lost 
by having too much water during winter or early spring, and even when the 
new growths are several inches long they should receive very little water. 
Red spider also has a particular fancy for it, and soon injures the young 
growths, if not kept in check, which should be done by sponging the under 
side of the leaves with weak fir-tree oil and water. 
‘‘D. Falconeri is also subject to the attacks of red spider, and should 
be carefully watched. I find it grows best when kept rather cool and. 
shaded during summer, and well saturated with water. More light should. 
be given in autumn to mature the growths, and during the winter it should 
be kept dry, to induce it to bloom freely. It is no doubt one of the hand- 
somest Dendrobes when in bloom, and well repays any care bestowed on its. 
cultivation. 
‘“No doubt the nobile section is the easiest to cultivate, and all are: 
beautiful when in bloom, especially D. nobile nobilius. D. n. Cookson~ 
ianum, D. n. pendulum, D. n. Hardyanum, D. n. Cypheri, &c. 
“It is not necessary to have a house specially devoted to Dendrobes, as. 
anyone having a warm plant-stove may cultivate many varieties to 
perfection. I have noticed better specimens in ordinary plant-stoves than. 
in a mixed house of warm Orchids, or in houses specially devoted to: 
Dendrobiums ; and they produce a beautiful effect, hanging in bloom from. 
the roof of any plant-stove.”
