258 THE ORCHID REVIEW. (Aucusr, 1913. 
Mittoniopas and OncipiopAs.—Other bigeneric hybrids having 
Cochlioda for one parent are Miltonioda and Oncidioda, and will be 
much sought after as they become more plentiful. In the cultivation 
of these bigeferic Orchids it is always safe to take the treatment of the 
predominating partner in the plant, that is, the parent which the plant in 
question most resembles. The Miltoniodas require more heat than the 
Oncidiodas, and the former are best treated as Miltonias, the latter as 
Oncidiums. The whole of these plants appear to have capabilities of 
making fine specimen plants, and when this is assured the effect will be 
wonderful. 
Ca@LocyNnEs.—Plants of C. cristata and its varieties are making rapid 
growth, and well-established specimens must not be allowed to suffer for 
want of water. Plants which have recently been disturbed should be 
watered sparingly until the new roots have become established in the 
compost. These cool-growing Ccelogynes should never, in their growing 
season, be exposed to a dry atmosphere; a damp situation is greatly to their 
liking whilst in growth. 
C@LOGYNE PANDURATA.-—Any plants which have passed out of flower, 
and which have outgrown their receptacles, may have new rooting material 
afforded them, provided they are pushing new roots from the base of the 
partly-made pseudobulbs. Owing to its rambling nature, this is a some- 
what difficult subject to keep in a limited space, therefore the old back 
bulbs should be taken away whenever repotting isdone. A similar compost 
to that used for the green-leaved Cypripediums will answer its requirements. 
There are other Ccelogynes which, like C. pandurata, thrive in the Warm 
house, and may also have attention as regards repotting should they be in 
need of it. 
CALANTHES.—The deciduous Calanthes, having now filled their pots 
with roots, must have more water, with occasional waterings of weak 
liquid-manure. This must not be given them too strong, as many cases of 
disease are attributable to excessive feeding. It is important that the 
plants should receive as much light as possible without being scorched by 
the sun. They should be grown near the roof glass, and be allowed plenty 
of fresh air, which consolidates the growth as it is made. 
CypRIPEDIUMs of the winter-flowering section are now in full growth, 
and should be freely supplied with water at the roots, and on bright days 
may be sprayed overhead. They may receive a supply of fresh air oP 
every favourable occasion, and on warm nights a little ventilation will be 
beneficial. When these plants are grown in a hot and close atmosphere 
the foliage is limp and soft and the flowers weak. 
LA&LIA ANCEPs and its varieties are fast developing their pseudobulbs, 
and the flower spikes are also pushing up freely. Liberal supplies of water
