THE ORCHID REVIEW. 367 
for giving a display for the Christmas season, for which reason a large 
quantity should be grown. If given cultural treatment as previously 
advised in these Calendars, it is one of the least difficult species to grow, and 
can always be relied upon to bloom well. 
The deciduous Calanthes are also highly prized for mid-winter blooming. 
They should now receive very little water indeed, and, after blooming is 
over, none at all, but be stored away in some dry place in the warm house, 
such as a shelf or some similar place where there is good light. It is 
letting Calanthes rest in a Cool temperature, and perhaps in a dark, damp 
position, that is mainly accountable for the disease known as the Spot 
appearing during summer when growing. 
Odontoglossum cirrhosum is now sending up flower spikes. It is an 
extremely pretty species when well grown. It does very well in the Cool 
house during summer, but should always be removed to an Intermediate one 
for the winter. It is so with O. Harryanum, O. Insleayi and its varieties, 
O. hastilabium, and O. Reichenheimii. O. citrosmum, an intermediate 
species, which has now completed its growth, must be kept very dry for the 
winter, in order to secure flower spikes in the spring. 
A grand old Orchid for winter is Zygopetalum intermedium. Its spikes 
are now far advanced, and the flowers will soon expand. Immediately 
after they have faded is a very good time for re-potting, as new roots then. 
push forth. The pot should not contain more than one third its depth of 
drainage, being then filled up with a rather generous soil, composed of 
turfy loam and peat in equal proportions, with a liberal quantity of sharp 
sand added, into which the plants should be re-potted when pot-bound with 
roots. A grand thing also is Miltonia spectabilis Moreliana, now in 
bloom—the colour is intense. Like all others of the same genus, it is safer 
at all times to under- rather than over-water. This species is best grown in 
baskets, in a mixture of two parts fibrous peat to one of moss pressed in 
firmly, and seems to prefer the Cattleya house in summer and the East 
Indian house in winter. If the new growths are trained so that they keep 
within the bounds of the basket, and the watering carefully performed, 
re-basketing in scarcely ever required. Non-disturbance of the roots should 
be the one great aim, not only with this species, but with most others also, 
therefore every possible means should be adopted to make the compost last 
the longest period in a sound and sweet condition. Careful watering, 
perfect drainage, and sound materials forming compost, are essential. 
Keep Coslogyne cristata dry and cold in a greenhouse temperature 
until the end of February, if successful blooming and strong growths after- 
wards are desired. When contemplating re-potting Cypripediums, remem- 
ber that they always flower more freely when confined to rather small 
receptacles and are somewhat root-bound.
