276 THE ORCHID REVIEW. (SEPTEMBER, 1914. 
similar Orchids, as light and air are important factors in ripening the growths. 
CaTTLEyas.—Among the Cattleyas that flower in the early and late 
autumn are C. Eldorado, C. Loddigesii, C. Leopoldii, C. granulosa, C. 
bicolor, and the beautiful C. Dowiana aurea. A quantity of the latter 
is often met with in establishments largely devoted to Orchids, where a 
succession of flower can be maintained for several weeks, which is a great 
advantage to the hybridist. When the blooms are removed the plants will 
remain dormant through the winter, and must not be overwatered, 
although any undue shrivelling of the pseudobulbs should be guarded 
against. Examples bearing seed capsules ought to be watered more freely, 
and suspended in a light position a few feet from the glass. 
L&LIOCATTLEYAS.—These give a good account of themselves throughout 
the year, and especially from now onwards. Many will be pushing up their 
spikes, others will be completing their season’s growth, and a few may 
require repotting. When this operation is finished, they can be placed at 
the warmest end of the house, and if they are carefully watered no harm 
will accrue. Shade will only be needed through the middle of the day, as 
dense and excessive shading has detrimental effect upon all the Cattleya 
tribe, particularly just prior to the winter months. 
MASDEVALLIAS.—In the February issue I referred to this quaint and 
interesting genus, and suggested that any not in a condition for repotting 
at that date should be left over until the present month. The winter- 
flowering kinds, of which the chaste M. tovarensis may be cited as 40 
example, ought not to be disturbed at this season, and the same rematk 
applies to the Chimera group, unless the compost is in a sour condition, 
when it is advisable to renew it at once irrespective of rules. Then we 
have the brilliantly coloured and strong-growing group, such as M. 
Veitchiana, coccinea with its numerous varieties, and ignea, which cat 
safely be repotted where the plants are pot-bound. Few Orchids respond 
more readily to generous treatment than these Masdevallias, and if carefully 
watered for the first two months or so they will soon take possession of the 
new compost. Where a house or division is not set apart for them, 
the warmest end of the Cool house should be chosen, preferably the 
shaded side. The base of the plant must not be elevated above the rim 
of the pot, and at no time ought they to suffer from dryness at the root 
They are subject to attacks from thrips, and the under-surface of the leaves 
should be examined periodically. I have heard that a mite (similar to 
Begonia mite) causes disfigurement of the foliage, but cannot vouch
