PROPAGATION BY DIVISION 35 
or more pseudo-bulbs together. This operation can be 
done at any season of the year, but it is most convenient 
to do it at potting time, and, for preference, just before the 
commencement of the natural growing season of the plant. 
Small pieces should be placed in small Orchid pans or 
baskets, but larger ones may be potted at once and placed 
on the stage with the other plants. 
Dendrobiums may also be propagated by dividing the 
plants, but a large section of the genus may also be pro- 
pagated by cuttings of the pseudo-bulbs. This method 
is specially useful for increasing a rare and fine variety 
of Dendrobium nobile or others of the section, as a good 
supply of plants can quickly be obtained in this way. The 
method is to cut the pseudo-bulbs into lengths of two 
or three inches and to place them in small Orchid pans, six 
or eight in a pan, suspending the pan in a warm, moist 
house. The Thunia section of Phaius, Epidendrum radi- 
cans, and some other Epidendrums and Orchids of similar 
growth may be multiplied in this manner. Further re- 
marks on propagation will be found under the names of 
the genera enumerated. 
CHAPTER VIII 
WATERING EPIPHYTAL ORCHIDS 
Success or failure with any class of Orchids depends 
largely on the exercise of discretion in watering. While 
it may be said that more specimens are lost by having too 
little water, especially among the smaller-growing species,
