230 THE ORCHID REVIEW. [OcToBER, 1917. 
observed to be pushing any necessary repotting may be done. They 
succeed in shallow pans, suspended from the roof, and a similar compost to 
that used for Cattleyas will answer their requirements. For these small 
growing plants it is necessary to cut the material smaller than when potting 
plants of larger stature. 
OponToGLossuMs.—The newly-potted plants of this genus should be 
carefully looked over to see when water is required and watch should be 
kept for any slugs which may have been brought in from the new materials. 
O. grande, O. Insleayi, and O. Schlieperianum are generally called the 
autumn-flowering section. They are plants of easy culture, and their large 
flowers are most valuable during the winter months. They are best 
accommodated at the coolest end of the Intermediate house, and delight 
in liberal supplies of water at the roots whilst making their growth. After 
flowering they enjoy a season of rest, when only sufficient water to keep 
them plump 1s necessary. 
PHAL&Nopsis, Vandas, Aérides, and other bulbless Orchids will require 
less water, both at the roots and in the atmosphere, during the dull days of 
winter. When the tips of the roots become sealed over they will require 
only sufficient to prevent the plants suffering. They should receive the 
maximum amount of light during the short days. 
MILToniAs.—Miltonia spectabilis and its variety Moreliana, with M. 
Clowesii and M. Regnellii, are interesting members of this genus, producing 
flowers during late summer and early autumn. After the plants have 
bloomed, and the pseudobulbs have finished growing, the supply of 
moisture at the roots should be gradually reduced, and the rooting material 
kept on the dry side until growth becomes again active in the new year. 
M. Roezlii, its variety alba, and M. Phalznopsis are plants not often seen 
in good condition at the present day. Their constitution is not so strong 
as M. vexillaria, and they should therefore have every attention. They 
require a slightly higher temperature than M. vexillaria, and should be 
grown at the warmest end of the warm Cattleya house. Those plants 
which have commenced to grow may be repotted, should they require new 
rooting material. They succeed in a similar compost to M. vexillaria, and, 
like that species, must have water applied sparingly until they have taken 
hold of the new material. 
CYMBIDIUMS.—Strong healthy plants of Cymbidium Tracyanum, C.- 
Lowianum, C. insigne, and many hybrids that are now showing flower 
spikes, should not suffer for water at the root, others which have not as 
yet shown their spikes should be kept on the dry side for some little time 
longer, otherwise growth will commence and the plants fail to bloom. 
Plants of this genus that are in a pot-bound condition will derive benefit 
from occasional waterings of weak liquid manure.
