THE ORCHID REVIEW. gt 
water. When fumigation has to be resorted to for the other inmates of the 
house, I always take the Calanthes out, as the tips of the leaves often turn 
black through tobacco smoke. Calanthe Regnieri and varieties nivalis, 
Sanderiana, Williamsii, and Stevensii will now be in full bloom. They are 
all deserving of cultivation, and help greatly to prolong the Calanthe season. 
The flowers show off to the best advantage when the plants are stood on 
the ground intermixed with ferns. Arranged in this way, the strong, arch- 
ing spikes have a charming effect. 
The rare Eulophia guineensis may also be re-potted now, and should be 
treated the same as the Calanthes in nearly every respect, except that it 
requires more shade when growing. 
Thunias will now require re-potting. The most convenient way is to 
plant six or seven bulbs about three inches apart, in a ten-inch pot, which 
should be half filled with drainage, using loam, peat, and moss in equal 
proportions. Choose a light position in the hottest house and as close to 
the roof glass as possible. The successful blooming of these plants depends 
largely upon the amount of light they get. Each bulb will require a stake 
tohold it frm. If the bulbs are very long, bend them over and tie them 
down, by which means the young growths may be brought near to the light. 
When the growths have started well, and are rooting freely, give 
abundance of water, and an occasional dose of weak liquid cow manure. 
Thunias may be easily propagated by taking off the back bulbs, cutting 
them at the joints into pieces about six or eight inches long, and insert- 
ing them as cuttings into a mixture of sphagnum and coarse silver sand. 
Both curious and extremely interesting are the genera Mormodes, 
Catasetum and Cycnoches. Some of the flowers are very sensitive, ejecting 
their pollen at the slightest touch, others are deliciously scented, and to a 
keen and intelligent observer the construction of the flowers appears marvel- 
lous. Being generally considered difficult plants to preserve in sound 
condition for any length of time, they have been ignored by many ht 
I have experimented with them in several different composts, and have 
found them to succeed best and last longest when grown in chopped 
sphagnum well mixed with crock broken up very small. Immediately they 
commence to grow, they may be shaken out of their old compost and re- 
Potted, using well-drained, shallow, hanging pans, the wire of which, being 
about twelve inches in length, will bring the plants well up to the light. 
ne the next few weeks after re-potting, water very sparingly, ets when 
roots have obtained a firm hold, give abundance. The south side of the 
hottest house will be the most suitable place in which to grow them, but 
When gtowth is completed, a drier and more sunny position is required to 
thoroughly mature and harden the newly made pseudobulbs, a condition 
“sentially necessary for their well being. The resting season S
