OCTOBER, 1910.] THE ORCHID REVIEW. 303 
the stem and sheath should be cut off as close to the bulb as possible, as 
the thick sheath is liable to decay, and cause the bulb to rot. They seem 
to be very susceptible to this, for at this time of the year there is not enough 
sunlight to dry them up properly. C. Dowiana aurea, C. X Hardyana, and 
others now flowering, as they pass out of bloom, should be kept drier at the 
roots. All Cattleyas and allied species should have all the light possible 
without causing injury, to harden them up for the winter, as owing to the 
dull weather we have had lately, they are at present very soft for the time 
of year. 
By this time many of the spring flowering Cattleyas, such as C. Triane, 
C. Mendelii, and others of that class, will now have finished up their 
growths, and will require less moisture at the roots. As they mature their 
bulbs:they should‘have only sufficient water to keep the bulbs: plump, and 
help the root action, which continues for some time after, as can easily be 
seen by the number of young roots pushing from the base of the new bulb. 
These should be carefully looked after, for the plant will require them when 
in flower. On the other hand, care must be taken not to give too much, 
either at the root or in the atmosphere, as this is a frequent cause of black 
rot, often seen among Cattleyas, especially if a fall in the temperature 
occurs when they are wet. I think it is best to err on the dry side rather 
than on the wet. Keep all Cattleyas and allied seedlings growing. Do not 
let them suffer in any way, and where there is not a special house for them 
they should be placed in the warmest and lightest corner that can be found, 
where they can be well looked after, and have plenty of moisture. 
CaLocynrs.—C. Massangeana, which flowers at different periods of the: 
year, and some of which are in flower now, make a pleasant change in the 
Cattleya house, where their pendant spikes look very pretty hanging from 
the roof. Others, in various stages of growth, will keep up a good 
succession for some weeks. C. Dayana is now growing strongly, and as 
soon as the bulbs are fully made up should be kept rather on the dry side, 
but not allowed to shrivel. C. cristata and its varieties, growing in the 
Intermediate house, are now making up their young bulbs, and should have 
abundance of water until fully made up. Alternate waterings with the 
liquid manure previously recommended will be very beneficial to them now. 
CoMPARETTIAS.—C. coccinea and C. falcata, at the warm end of the 
Intermediate house, are now ready for repotting—if requiring it—and C. 
macroplectron will be ready at the end of the month. They require the 
same treatment as recommended for Rodriguezias. 
Cympipiums.—C. Tracyanum and C. giganteum are now fast making 
up their growths, and some of the earliest are already showing their flower 
spikes. Any that are at all pot-bound will do all the better if they are 
given the help of liquid manure when watering. They require an abundant
