239 THE ORCHID REVIEW. [Aucust, 1915, 
to clear sunshine, taking care to choose a position where the plants will be 
free from draughts or cold winds. When fully exposed to clear sunshine, 
the compost, being filled with roots, dries very quickly, but careful 
judgment should be exercised in watering. Avoid keeping the roots in a 
constantly saturated condition. Those plants that are well established in 
small pots will need water more often than the larger specimens ; in either 
case, when once a thorough watering has been given, the plant should 
receive no more until the whole compost has become dry. The aim of the 
grower should be to water the plants just often enough to keep the roots in 
a healthy condition and to prevent undue shrivelling of the pseudobulbs, 
also to ripen and consolidate the newly-made growths by affording as much 
fresh air and sunshine as possible. 
Among the early varieties to finish up their growths are Dendrobium 
Wardianum, crassinode, nobile, crystallinum, &c., also a large number of 
hybrids far too numerous to mention. Those that have not yet finished 
their growth, as D. superbum and its varieties Huttonii, Dearei, Burkei, 
and anosmum, also several of the taller-growing species, D. Dalhousieanum, 
&c., should receive every encouragement as regards heat and moisture until 
they are so far matured that they too may be gradually dried and hardened 
off. 
Dendrobium Maccarthiz is a lovely species, but difficult to cultivate for 
long together. It prefers a Cattleya house temperature, with plenty of 
water at the roots, and the only rest this plant appears to require under 
cultivation is for a few weeks just previous to flowering. Plants of this 
species should never be subjected to deep potting; a thin, shallow well- 
drained compost of osmunda fibre answers best. Plants of D. Phalaenopsis 
that are in small pots or shallow Orchid pans are now making roots freely 
and strong rigorous growth. They should be afforded every encouragement 
until the new pseudobulbs are completed. Elevate the plants as near to 
the roof glass as possible in the warmest house or plant stove. They 
delight in as much sun-heat as is possible to give them, and a very thin 
shading only is necessary, even during the hottest day in summer. When 
thoroughly well rooted in small pots these plants require almost unlimited 
supplies of water, with abundance of atmospheric moisture after the house 
is closed and the shading removed for the day. 
Plants of Dendrobium Bensonize that have recently passed their 
flowering stage will have made considerable progress with their new 
growths, and as these commence to push out numerous roots when only a 
few inches high, no time should be lost in affording fresh compost to those 
that require it. Repot the plants into a shallow compost of osmunda fibre, 
and place them alongside, and under the same conditions as D. Phalaenopsis.
