334 THE ORCHID REVIEW. [ NOVEMBER, !9To. 
the roots at any time, or the next seasons growth will come weak, and 
perhaps the plant will not start at all. 
ODONTOGLOssuMS.—O. citrosmum, having completed its season’s 
growth, should be removed to a light position in the Intermediate house, 
and only sufficient water given to help them to fully make up their bulbs, 
which ought to be by the middle of the month. Afterwards they will go 
for long periods without water, in fact, if properly ripened up, they will go 
right through the winter, until the spikes are seen pushing from the centre 
of the young growth, without a drop of water. They must have a very 
decided rest if they are to be induced to flower. O. bictoniense and its 
beautiful variety album are now in flower. They should be grown all the 
year round with O. Uroskinneri at the cool end of the Intermediate house, 
as the foliage is liable to spot if grown too cool. O. grande, Insleayi and 
Schlieperianum, now in flower and bud, are also best in the same house 
whilst in flower, as the flowers soon spot if left in the Odontoglossum house. 
Plants of O. crispum that were repotted as advised in September will now 
have got rooted again, and the supply of water may be increased according 
to requirements. Continue potting any that require it as they become 
ready, as it is better than leaving them to starve. 
THE AMATEUR’S COLLECTION. 
AUTUMN is a particularly gay season of the year in the Amateur’s collection. 
Cattleya species and hybrids, Leliocattleyas, Oncidiums, Odontoglossums, 
the now vast Cypripedium family, and a few other groups offer such a 
wealth of material that selection becomes a somewhat arduous task. 
Among the Cattleyas the fine old C. labiata is now flowering freely, and 
both the coloured and the rarer white varieties are very effective. As they 
pass out of bloom, the spathe and the old flower spikes should be cut clean 
out, as close to the base of the leaves as possible, so that no material is left 
to decay and pass down into the healthy tissue beneath. Some of the 
hybrids of C. labiata are very desirable acquisitions, and more easily grown 
than the species, the beautiful C. x Fabia being especially noteworthy in 
this connection. The other parent, C. Dowiana aurea, is also in bloom, 
and is exquisitely beautiful, though not an easy plant to grow under 
ordinary conditions. C. X Mantinii, the hybrid between C. D. aurea and 
C. Bowringiana, is one of the best of autumn bloomers, and is now making 
a fine display, with a few other hybrids of the last-mentioned. 
Some of the diphyllous Cattleyas have been flowering well. C. 
Loddigesii is very varied in its season of blooming, and good forms are 
always attractive, while several of its hybrids with species of the labiata 
group are in bloom, and of great decorative value. The hybrids of C. 
bicolor are very useful at this season, particularly C. x Iris and C. xX
