44 THE ORCHID REVIEW. (FEBRUARY, 1916. 
class of plants individually, as no good results are attained by continually 
‘altering the method of cultivation. Any plants which are in decomposed 
material should be placed in new, whenever it is observed they are about to 
make new roots. 
ODONTOGLOssuMS and ODONTIODAS may, for cultural purposes, be 
placed together, as both succeed under similar conditions, and the remarks 
made last month are applicable during the present one. O. grande, O. 
Insleayi, O. Williamsianum, and allied plants that are at rest, will require 
little water at the roots until growth commences. 
CATTLEYAS and ALLIES.—Cattleyas, Lzliocattl B ttl , and 
allied plants have now attained such numbers, and aie such vasiels of 
colour, that they are indispensable, as their lovely flowers may be enjoyed 
the whole year round. The remarks made last month are applicable for the 
whole of the potting season. Cattleya Warneri,'C. Warscewicizii (gigas), 
L. Boothiana, and L. crispa, as they commence to grow, may have the 
water supply gradually increased, taking care that the compost becomes 
dry between each operation. 
MExIcAN La ias are, with me, slightly later than usual this seasor. in 
producing their flowers, and any that are in need of new material at the roots 
may have attention as soon as the flowering period is over. I find these 
plants succeed in all osmunda fibre, pulled into pieces, and potted 
firmly. I grow them all i in shallow pans in preference to baskets or other 
receptacles. 
CYPRIPEDIUMS, as they pass out of flower, should be repotted if the 
compost is at all decomposed. A suitable mixture was given last month, 
and if the plants have attention as they pass out of bloom they get estab- 
lished before the hot weather comes upon them. 
DENpDROBIUMS of the nobile section, although not so popular as they 
once were, are still most useful, and, when well grown, most beautiful. 
‘There are legions of varieties to select from, and a great variety of colour, 
as in the case of all Orchids taken up by the hybridist. Those which have 
their flowers in an advanced stage may have water afforded them in more 
liberal quantities as soon as the flower buds are about half-developed. 
Before the flower buds attain any size it is advisable to thoroughly clean 
the plants, as when they are larger many may get damaged. These plants 
open their blooms quite satisfactorily in a temperature of about 60°, and 
last much longer either in a cut state, or upon the into than when forced 
into flower in a higher temperature. 
CYMBIDIUMS are another group of plants in which the newer hybrids are 
great improvements upon many of the species, and should be represented in 
all collections where choice flowers are in request. Any plants that are 
pushing up new growths, and are ir need of new material, should be
