10 THE ORCHID REVIEW. (JANUARY, 1907 
perpetual flowering Orchids have been freely producing their useful blooms — 
since early autumn, and they are well worthy of more extended culture. 
The varieties now in flower with us are S. aurea, S. x kewensis. S. X 
Colman, S. X aureo-Vieillardii. The treatment necessary is to give them 
a humid spot in this house, and to see that they never, at any time, suffer 
from want of water at the root—that is to say, the evergreen varieties,—for 
the deciduous S. Fortunei requires a thorough rest during the winter 
months, maintaining this course till the young growths show signs of 
activity in the spring. It is not desirable to place this variety in a cooler 
house, as withholding water will give all the rest required. 
The compost we find most suitable, for all of them, is two parts good 
fibrous loam, and one part each of peat, leaf soil and sphagnum moss, these 
being well mixed together, with a liberal sprinkling of coarse sand and 
small crocks. Ordinary pots, that are provided with three holes just under 
the rim for suspending them, are the best receptacles. A fair drainage of 4 
few crocks should be given, and over this a layer of chopped sterilized 
bracken rhizomes, filling the pots to one-third of their depth. Pot 
moderately firm, leaving enough room to allow of a top dressing of 
chopped sphagnum. 
Fotting should be done when the young growths are about two inches 
high, taking no notice of the time of year. As they are such vigorous 
growers they soon exhaust the compost, and we find it good policy to repot 
them each year. In doing this, shake out as much as possible of the old 
material, and remove any back bulbs there may be behind the first two. I 
there is a desire to increase the stock, the back bulbs, if laid between plants 
on the stage or potted up in sphagnum, will soon grow away. After 
potting, especially when done during the winter season, water should be — 
given with discretion till the roots have entered the new compost, striving 
to maintain it neither wet nor dry, but in that constantly humid state sO — 
much appreciated by many plants after disturbance of their roots. 
BULBOPHYLLUM BARBIGERUM.—This charming curio is now with us in 
active growth, and should it be necessary to repot or resurface it, the most 
desirable time is when the young
