founded. The species are scattered over tropical India, 
Burmah, and the Islands of the Malayan Archipelago. 
Culture.—In their natural state, Saccolabiums grow on 
the upper branches of trees in some of the moistest and 
hottest regions in the world: under cultivation they there- 
fore require stove treatment. During the growing season, 
which extends from March to October, a temperature 
ranging from 7odeg. to 80deg. is needed, whilst on very 
hot days it may safely be allowed to rise 5deg. to rodeg. 
higher. When growth has fairly commenced, the plants 
must be kept uniformly moist at the root, and the atmo- 
sphere as saturated as is consistent with adequate ventila- 
tion. The walls, floor, staging, and, in fact, every available 
space, should be frequently wetted, and towards evening 
on the brightest days a fine spray may be distributed over 
the plants by the syringe. One of the commonest errors 
in the cultivation of Saccolabiums is that of keeping them 
too much shaded. Only during hot sunshine is it necessary 
to let down the blinds. For this reason it is a convenient 
arrangement during the season of growth to place the 
plants on the same side of the house as the Dendrobiums. 
They thrive best when suspended about 8in. from the roof- 
glass, and should be planted in teak baskets, partly filled 
with clean potsherds and pieces of charcoal, finishing at 
the top with a good layer of live sphagnum. If it is not 
possible to suspend them, the next best method is to 
grow them in cylinders gin. to 12in. high, with cross- 
pieces half-way down, the lower half remaining empty. 
About the end of February the roots become green at 
the tips, and commence to lengthen. As soon as this is 
observed, the old sphagnum should be removed and re- 
placed with new, at the same time cutting off decayed 
roots, and thoroughly cleansing the plants. If, as is 
usually the case, the roots are clinging to the basket,
