NOVEMBER, 1913] THE ORCHID REVIEW. sary 
may consist of the same material as used for the green-leaved Cypripediums,. 
but must, owing to the smallness of the plants, be pulled into smaller 
pieces. The pans should be filled one-third of their depth with clean crocks. 
for drainage, and care should be taken not to damage the young roots 
which are pushing, as they are very susceptible to injury. After potting, 
the usual care and attention is necessary in the application of water to the 
roots until the plants are nicely established. The plants should be grown 
suspended during the winter months in a light position at the warm end of 
the Intermediate house. The cooler-growing varieties, as P. humilis, 
Hookeri, and yunnanensis, having completed their season’s growth, are 
best suspended from the roof of the Odontoglossum house, and require only 
sufficient water to maintain the pseudobulbs in a plump and _ healthy 
condition. The re-pottirig may be done when their flowering season is past. 
PHALZNopsis that are developing their flower spikes must now be 
watered with great care ; especially so should foggy or bad weather prevail,. 
large supplies being no longer needed. It is not good practice to dip the 
plants or otherwise saturate the compost. Generally speaking I am 
opposed to dribbling of water to plants, but in the case of Phalzenopsis 
extreme care is necessary, especially at this season, in the application of 
water to the roots. A slight sprinkling round the sides of the baskets, 
sufficient to keep the sphagnum moss in a living condition, is all that is 
necessary. All the tender, green-leaved species require careful watering, 
and should not be subjected to direct sunlight, even in winter. 
Mrxican La&.ias.—At the present time many of these plants, such as. 
L. albida, L. autumnalis, L. Gouldiana, and the numerous varieties of L. 
anceps are developing their Hower spikes, and care should be taken that 
none of them are allowed to suffer injury from cold by touching the glass.. 
The flower spikes should be carefully tied down to neat stakes, so that they 
derive all the benefit of whatever light and sunshine we may get. Wood- 
lice at this season do irreparable damage to the roots, and should be 
frequently searched for and destroyed. During the flowering season the 
plants need only sufficient water to keep the compost moist, and afterwards. 
still less will suffice, until growth recommences. 
BaRKERIAS.—The different species of Barkeria are difficult to cultivate 
for long together, and for that reason are very seldom seen. These plants 
succeed under much the same conditions as Lelia anceps, exposed to 
all the light possible, with a liberal supply of fresh air at all times. 
DENDROBIUMS of the evergreen section, such as D. thyrsiflorum, 
densiflorum, and allied species, have now finished their growths, and should 
be placed in a cool intermediate temperature to rest. Afford them just 
sufficient water to keep the leaves fresh and the pseudobulbs from 
shrivelling. The leaves should occasionally be examined for red spider,.
