300 THE ORCHID REVIEW. [OcToBER, IQII. 
provided they are pushing new roots. They should be kept on the dry side 
until the new roots are seen to be getting through the new compost. This 
I consider to be one of the best seasons of the year to repot Cattleya 
Warscewiczii, or gigas, keeping it on the dry side until it commences to 
grow in February, and placing it well up to the light, at the warmest end of 
the Cattleya house. Some plants of this species are undoubtedly more 
shy flowering than others, and in no case will small plants flower as 
freely as C. Mendelii or C. labiata. If the conditions laid down be carefully 
carried out, I think the most obstinate plants will flower in due time. I 
may say the plants must not be allowed to shrivel or lose their leaves for 
the want of water during the winter months, as they lose their roots at the 
same time. I make these remarks in answer to a note and our Editor’s 
remarks thereon at page 271. 
OponTOGLossuMs.—The repotting of this family should be completed 
as soon as possible, and any that are not in a fit condition now will be best 
left over until the early spring. Any plants that are pushing up spikes should 
be elevated so that they obtain all the light possible, and any weak or sickly 
plants attempting to flower should have the spikes removed at once. The 
sole aim of the cultivator should be to nurse his plants until they attain the 
strength and vigour to carry a spike of ten to fifteen or more flowers. This 
cannot be expected from weak plants. 
CALANTHES of the vestita section that are now pushing up their spikes 
will also commence to cast their foliage, and must be watered with 
moderation until the blooming period, and must have all the light possible, 
which will enable them to expand and develop their flowers. They should 
still be kept in the same house and temperature as they have made their 
growth in. C. Regnieri, C. Turneri, and others are later in losing their 
foliage, therefore the treatment must be varied accordingly. 
CympBipiums.—C. Tracyanum, Hookerianum, and giganteum are now 
fast finishing their growths, and some of them are already pushing up their 
flower spikes, and will be all the better for an occasional watering with 
weak liquid manure-water, but in no case must it be administered in strong 
doses, rather withhold it altogether than run the risk of doing them harm. 
SOBRALIAS may be repotted at this season, and as they are all strong 
_growers, they require plenty of pot room. The compost I recommend for 
them is equal portions of fibrous loam, osmunda, peat, and sphagnum moss, 
all thoroughly mixed together, and used in a fairly rough state, potting 
rather firmly, and leaving a space of half an inch or so below the rim of the 
pot for watering. For some time after repotting the soil must be kept on 
the dry side, and no water should be given until the compost becomes dry. 
They succeed best at one end of the Intermediate house, where they can be 
accommodated with plenty of head room.
