322 THE FLORAL WORLD AND GARDEN GUIDE. 
completeness. Several large-flowered species, with beautiful delicate 
rose-tinted flowers have within the last few years beea introduced 
by Mr. Bull of Chelsea, but as yet they are too rare to justify the 
amateur in taking them in hand, The established kinds are so 
exceedingly good that they are quite sufficient for any ordinary 
collection, and it may also be added, that with a goodly number of 
plants, P. amabilis and P. grandiflora may be had in bloom during 
the greater part of the year. 
The phalenopsids are natives of Borneo, Moulmein, Burmah, 
Philippine Islands, and Manilla, and therefore require for their 
successful cultivation a high temperature throughout the year. In 
the matter of warmth they do exceedingly well in a house, the tem- 
perature of which ranges trom 70° to 75° during the growing season, 
which usually commences in March and terminates in November, 
and from 60° to 65° during the resting season, from November to 
the end of February. The minimum of each season represents the 
night temperature and the maximum the day temperature, when 
maintained by artificialheat. But throughout the year an additional 
five, or even ten degrees may be allowed during periods of bright 
sunshine, provided that during the summer season the house is 
properly shaded, and the atmosphere fairly charged with humidity. 
The hardiest of all the species at present in cultivation is the subject 
of the accompanying illustration, but to maintain it in health the 
temperature must not, during the winter season, fall much below 60°. 
All the species are epiphytal; that is to say, they grow in their 
native habitats on the trunks and branches of forest trees, and one 
or two grow on masses of rock. Hence it may be inferred that they 
do not require a large mass of material, such as peat or sphagnum, 
for the roots to run into. They may, indeed, be grown upon blocks 
of wood, with or without moss attached, and suspended from the 
roof, and in shallow baskets; but, excepting newly-imported and 
small plants, the best results are obtained by growing them in pots 
prepared as I shall now describe. We will suppose it is desired to 
repot a medium-sized plant furnished with healthy roots. For a 
plant of this kind a six-inch pot will be the most suitable, and it 
should be prepared by filling it to within about two inches of the 
rim of the pot with rather large crocks and small lumps of charcoal. 
To make the surface moderately even, put a few smaller crocks on 
the top, and cover with a layer of sphagnum. ‘The plant can then 
be placed in position, and have a mixture consisting of sphagnum 
moss, crocks, and small lumps of charcoal packed about the roots to 
form a mound some three inches or so above the rim, and over the 
surface spread a thin layer of sphagnum to give the work a neat ap- 
pearance. More fully-developed specimens are, as a matter of course, 
put into pots proportionate to their size with larger pieces of crock 
and charcoal, and they are raised rather higher above the rim. 
When they are grown in baskets, the latter should be filled to about 
one-half their depth with crocks, and the base of the plant raised 
just above the upper edge. In transferring them from one pot to 
another, the loose material must be removed from about the roots ; 
but in doing this they must not be injured; and when a root is found
