16 THE ORCHID REVIEW. [JANUARY, 1917. 
kinds as M. spectabilis and its variety Moreliana, should be examined to 
see if any of the plants are in need of more pot room, as the present is the 
best season to repot them. The whole of these Miltonias thrive satis- 
factorily in a shady part of the Intermediate house, and appreciate light at 
this season, but during the summer months direct sunshine is detrimental 
to their growth. For sometime after repotting water must be given with 
great care, as the young growths are liable to decay if too much is given 
until they are thoroughly re-established. A compost of equal portions 
of osmunda and Ar fibres, with a little sphagnum moss, answers their 
requirements. This material should be placed firmly around the rhizome 
of the plants. 
C@LOGYNE CRISTATA and its varieties are now pushing up their flower 
spikes at the cool end of the Intermediate house, and must have water 
applied to them whenever they become dry. C. Mooreana is a valuable 
addition which flowers at this season, and, when better known, should find 
a place in most collections. It is easy to grow if treated much in the same 
way as C. cristata, but prefers the warm end of the Intermediate house. 
Like many of the other species of this genus it likes a moderately-shaded 
position. C. pandurata, C. Massangeana, and others must have water 
according to their condition, those at rest requiring little, whilst those 
pushing up flower spikes or in growth must have water whenever the 
compost becomes dry. 
DENDROBIUMS.—Plants that are resting in a house that is kept at a 
temperature of about 55° should not be allowed to shrivel for want of 
water, just sufficient should be given to keep them plump. If early flowers 
are required, those plants which have their flower buds well advanced may 
be placed in a light position in slightly warmer quarters, but no undue 
forcing should be attempted, or the plants will rush into premature growth 
and the whole crop of flowers may be lost. 
ZYGOPETALUMS.—Such plants as Z. Mackayi, Z. crinitum, and others 
of this section should be repotted, if necessary, as they pass out of flower. 
The roots of the different species and hybrids vary to a considerable extent, 
some making large succulent roots, others of a thinner and more wiry 
nature. Those with large Cattleya-like roots may have larger receptacles 
than the others. The strong growers may also have a more substantial 
material to root in. Fibrous loam, osmunda fibre and sphagnum moss, in 
equal Proportions, cut up according to the size of the plants and well mixed 
together, will form a suitable compost. In the more delicate growers, the 
loam fibre may be reduced. : 
cca ee good supply of the necessary potting material 
prepared as far as possible, so that when the busy 
potting season comes round everything is at hand.
