spike of bloom from its base. But each year the new growth became 
considerably less and less, until, and within a very short period, but few 
plants from those thousands were left alive. Its native habitat was-said to 
be Paraguay, where it was found growing on the top of trees, the climate 
being very hot—a vague account at least. Whether the collector could, or 
ever did give a more definite statement, I never knew, but if he did I never - 
heard it. I have tried it in all houses and all positions, but have so far 
failed to find the right one. I dare say its treatment is simple enough when 
known. Yet it is possible, of course, that it requires some peculiar treatment 
which it is impossible for us to reproduce artificially, in which case it wouldbe 
well to leave O. Jonesianum on its native trees at home. Perhaps, however, 3 j

there are some growers who have succeeded in keeping this plant alive, and ~ 
as sound in health as when imported ; if so, it would be interesting to many 
to know how it is done. In the meantime I can only say how I have found 
it grow best for the longest period. It should be wired to a block of wood 
—head downwards—that being its natural way of growing. If the block is 
green with the bark on su much the bettef. The plant should be transferred 
to a new block each year, about April, just as the new roots are appearing. 
It should then be suspended in a light position near the glass in the 
warmest house, and given plenty of water by syringing it. By autumn it 3 
will have made its growth and flowered, after which it should be kept very — sagt 
dry throughout the winter, only moistening the roots occasionally. The * 
temperature during the resting season should also be moderately warm. : 
Pleiones are now growing freely, suspended in a sunny position im 
aay. Ges They are fond of a good supply of water at the ’ 
root, and must never now be allowed to become dry. Syringe them at — 
least once a day. Sobralias are now showing for flower, and if at all 
pot-bound with roots, will be helped by an occasional watering with weak 
liquid manure. Stanhopeas should now be put in larger baskets if requl 
The baskets should be shallow ones, having no crocks placed at — 
bottom. They grow best in a warm house. Zygopetalums requiring 
tepotting should be delayed no longer. The strong growing kinds like 
Z.intermedium should have fibrous loam mixed in with the peat and moss: 
Others, such as Z. Gautieri, should be grown in baskets or on the stem of 
a tree fern. They are intermediate Orchids, and delight in a liberal supply 
of water during summer. 
Cymbidiums should be attended to as they pass out of bloom. They ate — ; 
best grown at the coolest end of the Intermediate house. A good compost 
of lumpy peat two parts, and one part of fibrous loam, with a little sand 
and broken charcoal mixed in to keep the whole sweet, is the best: 
Eulophia guineensis should also be potted in the same materials, but this
