FEBRUARY, 1922.] THE ORCHID REVIEW. 57 
month. It is one of the freest of Cattleyas to grow and flower, and forms 
a most useful and beautiful species, and asa parent it is found in quite a 
large number of hybrid Cattleyas and Leliocattleyas. After flowering, it 
soon commences to root and grow, when repotting can be undertaken. For 
compost, use equal parts osmunda fibre, Ar fibre, and see that the plants are 
secured and potted firmly. 
DENDRoBIUMS.-—Many of the D. Wardianum, D. nobile, and various 
hybrids are beginning to show flower buds on the stems. These should be 
assisted to develop by giving slightly more water at the roots and in the 
atmosphere. They will give better quality flowers if allowed to develop 
gradually and without the assistance of much fire heat. After flowering, 
and until new growth commences, give them quiet treatment fora tim», 
when repotting may be done if necessary. D. Phalenopsis, D. formosum, 
D. bigibbum, and D. superbum, which have now finished flowering in the 
warm house should, from now and until new growth commences, be given 
only sufficient water to prevent the pseudobulbs from unduly shrivelling. 
OpontToGLossum House.—The various species and hybrids contained i 
this house being at the present time in various stages of growth, will nee | 
constant attention in the way of watering and maintaining suitab'- 
atmospheric surroundings. A good many are pushing flower spikes, which 
must be protected from the ravages of thrips by placing cotton-wool around 
them and laying traps of bran and lettuce leaves about the plants and stages. 
See that the plants get all the light available at this time, and keep a 
buoyant atmosphere in the house by admitting air on all favourable 
occasions. 
CATTLEYA CHOCOENSIS.—When collecting Orchids in the Cordilleran 
area, Mr. J. E. Lager, of Summit, New Jersey, came across the home of 
Cattleya chocoensis, which, unlike many other Cattleyas, occurs in forests 
on level land which is very swampy, and where the trees are stunted and 
overgrown with moss. ‘‘Here I saw the most beautiful sight it has been 
my fortune to see; in these jungles the plants grew by the thousands, the 
trees being literally covered with them and in full bloom. I particularly 
remember that I got my mule under a tree, and, sitting in the saddle, 
picked a large bunch of flowers; these were particularly fine and large, so 
different from what we see them under culture, where they only half open. 
The treatment we give this plant under cultivation probably has something 
to do with this. Where they grow it is very warm and humid. I noticed 
in the early morning, as soon as the sun reached the forest, a dense mist 
would rise from the ground and would envelope everything; this would 
gradually disappear as soon as the sun became stronger.—Trans. Mass.
