OcToBER, I9gIT.] THE ORCHID REVIEW. 308 
OncipIuMs.—In the Cool house such Oncidiums as Forbesii, crispum, 
and varicosum will be developing their flower spikes, and strong, well- 
rooted plants may be allowed to bloom, but small, delicate, weakly plants 
should have the spikes removed. These plants produce an abundance of 
flowers from newly-imported plants, and soon exhaust themselves if allowed 
to retain these spikes for any length of time; therefore if it is desired to 
keep the plants from year to year, these spikes should be removed as soon. 
as they are fully developed. O. concolor and any others that have 
completed their growths or pseudobulbs will not require nearly so much 
water as they did when in full growth, but they must not be allowed to. 
suffer—that is, to shrivel—for want of it. 
Disas.— Where the lovely Disa grandiflora is grown the plants are best 
repotted at this season, just as the new growths push up from the sides of 
the old flower spikes. The pots should be well drained, using a compost 
of equal portions of fibrous peat and sphagnum moss, with a fair sprinkling 
of half-decayed leaves and coarse silver sand, or better still, powdered sand- 
stone, all mixed well together. After repotting give just sufficient water to. 
settle the compost, and then for some time spraying once or twice a day, 
or more, according to the weather, will suffice to keep them moist. They 
require a cool, moist position, in a freely ventilated house, where frost can 
be kept from them. Green fly and thrip are their greatest enemies, and 
must be kept at bay. 
MILToNIA ROEZLII and its variety alba will be commencing to grow, 
and may be repotted, should they require it, using the compost as recom- 
mended for M. vexillaria, and placing the plants well up to the light at the 
warm end of the Intermediate house. They delight in a fairly moist 
position, and water should only be applied at this season when the compost 
becomes dry. 
VANDA KIMBALLIANA, now developing their flower spikes, should be 
kept moist, and in a growing condition until their flowers are open, and 
afterwards only sufficient water should be given to keep their terete leaves. 
firm and plump. 
LycASTE SKINNERI.—Any backward plants of this species should be 
encouraged by placing them in a warmer position than that which they 
have occupied to enable them to complete their growths. They should 
have water whenever they require it until the bulbs are matured, and should 
be kept in a temperature of not less than 55° at night. 
MORMODES, CYCNOCHES and CATASETUMS that have finished their 
growths, and flowered, may be placed with the Dendrobiums in the resting 
house, and should only have enough water to keep them from shrivelling. 
ANGULOAS that have perhaps been grown in the Cool house during the 
summer months, must now be taken back to the Intermediate house, and”
