THE ORCHID REVIEW. 75 
intermediate in form between the parents. It now bears a fine pod crossed 
with its own pollen, and its pollen has also made large pods on C. Leopoldi 
and Epidendrum nocturnum. I hope it may transmit its constitutional 
vigour to some of its posterity. I have already two off-shoots four or five 
inches high from back breaks of this plant, which certainly grows like a 
weed. This was recorded as C. intermedia xX Harrisoniana (O. R. iv., 
p- 171), but it now appears that the second parent was C. Loddigesii. 
My seed planting was very successful after June in polypodium fibre 
(fresh fern mats) in my tree-top “‘eyrie”’ (see O. R. iv., p. 180), and from July 
to October I averaged five hundred little hybrids transplanted to pots 
every month. About one-fourth of them still survive. 
A mossy piece of magnolia bark (Magnolia grandiflora), about one square 
foot in area, was planted thickly with a mixture of Laelia and Cattleya 
crosses, and hung up in the greenhouse September 12th, 1898, just when the 
adult Orchids were beginning to do so badly. Two or three fumigations 
with ammonia were made after that, which may have stimulated the 
seedlings. At any rate, they made quick response, and at four weeks from 
planting I counted 160 opaque green disks, either with leaf points or nearly 
ready to push one. 
The block was dipped in a pan of water two or three times a day. 
Later, it was moved out-doors and sprayed frequently instead of being 
dipped. At eight weeks there were 320 plants; at twelve weeks, 347. 
Then it was moved back into the greenhouse, the weather became foul and 
dark, and the number of plants fell to 250 in a week, the loss being 
among the smallest plants. By the middle of January, some of the best 
ones, with two or three leaves, began to show black spots, and I trans- 
planted the remainder to pots—about 150 plants. 
Finding the experiment turning out so favourably in October, I had 
an ancient moss-grown magnolia chopped down and cut into slabs, some 
thirty of which I planted with hybrid Orchid seed, and kept sprayed. 
The slabs coming from near the ground scarcely germinated a seed, but 
those from 20 to 30 feet up yielded from two or three up to about 150 
plants each. I also tried oak bark, but while the seeds started promptly, 
giving leaf-points in three weeks, they seemed more subject to disease, 
and their number dropped from 250 at nine weeks to 175 at ten weeks, 
when they were transplanted to pots and nearly all died.
