THE ORCHID REVIEW. 173 
state little root action goes on until the bulbs have almost reached their full 
development, then they may have new material and be given a more 
bountiful supply of water. It is absolutely necessary that these should 
ripen their tall, stem-like bulbs before the winter sets in, or they will in all 
probability fail to pass through scathless. C. Rex has not fulfilled all the 
good things expected of it, especially in matters cultural. As we do not 
know the conditions under which it grows in its native state, we have to 
surmise, and experiment to find out its requirements, and often this means 
the sacrifice of one’s plants without arriving at any definite result. We are 
informed that it should always be kept in a moist condition, but, 
unfortunately for us, the moisture was too much for our plants, as they died 
an unnatural death. 
As soon as Dendrobium thyrsiflorum, densiflorum, Farmeri, clavatum, 
moschatum, and others of this section, have gone out of bloom, they will 
soon commence to grow, and when the elongation of the young bulb has 
reached the foliate stage, roots will appear at the base, and any re-potting 
or top dressing should then be done. The best fibrous peat, freed from all 
its finer particles, should be used, with a small proportion of clean living 
sphagnum. The quantity used to each should only be about an inch in 
depth, the remainder of the receptacle being filled with clean drainage. 
Secure the bulbs to a stake or two placed in the middle of the plant to keep 
it in shape, and water sparingly until the roots have worked their way into 
the new material. The lovely D. Falconeri should be grown in an airy part 
of the Cattleya house, either on a block or raft or in shallow pans or 
baskets. In either case very little material should be used, for although 
abundance of water is needed during tke growing season, the plants do not 
relish a soddened base. The small leaves of this species are very subject to 
the attacks of red spider, and to keep this pest at bay the plants may be 
given a bath for an hour or so daily. Re-potting is seldom necessary, as its 
mode of growing is more of a branching character rather than an extension 
at the base. Fresh material, however, may be given where any of the old 
can he picked out without damaging the fine wire-like roots. D. 
chrysotoxum and suavissimum flower and proceed to make new growth at 
the same time, but little root action is seen until the flowers are over, when 
potting or other necessary operations sould be attended to. These enjoy 
a short and quick growing seaon, and afterward a long rest. 
Arundina bambuszefolia is an Orchid seldom grown, yet when seen in 
flower always commands attention and well-merited admiration. It is a 
plant that likes a stove treatment alJ through the year. Just now it is 
pushing forth its new grass-like stems, and should, if needed, be repotted, 
using pots three parts filled with drainage, and a compost of two parts peat, 
one of fibrous loam, and some chopped moss and sand or finely-broken
