THE ORCHID REVIEW. 371 
Gardneriana, also in bloom, is of quite a different character, as its racemes 
of snow-white blooms are really of a meritorious order. It should be grown 
in a pot, adding a little loam fibre to the peat and moss for it to root in. It 
does not make many roots, and on this account is somewhat difficult to 
establish, firm potting being very necessary. An intermediate temperature 
suits its requirements, keeping it fairly moist at all times. 
The deciduous Calanthes, C. vestita, Xx Veitchii, and others of this 
section will now be coming into bloom, their nodding plumes adding greatly 
to the attractiveness of our stoves, although within the fog radius their 
beauty is short-lived if a visitation of fog occurs whilst they are in flower. 
Twice in eight years only have we had any worth looking at, and now we 
have concluded that it is no use attempting their cultivation in this district 
with any prospects of getting an adequate reward for our trouble. Even 
when the flowers expand, the dullness of the atmosphere prevents the 
development of their natural colours. The plants from now onwards will 
need little or no water, and after the spikes are cut may be laid on their 
sides in a dry, warm corner, or other suitable position, though if under a 
stage they should be removed far enough from the hot-water pipes not to 
become parched from their influence. The varieties Turneri and Regnieri 
do not come into bloom just yet, and for this reason are better adapted for 
cultivation in or near large towns. 
- The latter is one of the parents of a very useful generic hybrid—viz., 
Phaio-calanthe x Arnoldiz, which is much easier to grow than either it or 
its other parent, Phaius grandifolius, and combines in its flowers the good 
qualities of both. Seedlings of it are easily and quickly raised, and any- 
one desirous of raising hybrid Orchids should certainly give these two genera 
atrial. As the offspring are not deciduous, water is needed more frequently 
during the winter than Calanthes require, though a dry state of the root for 
a few days will do no harm, for the old favourite, Phaius grandifolius, thrives 
much better when kept moderately dry during the winter than when the soil 
is continually saturated, as, also, do most other species of Phatus. Even 
P. tuberculosus is all the better for being allowed to become dry before giving 
more water, for I find that P. x Cookson, which has blood of the latter in 
its composition, thrives better under a moderately dry treatment than when 
kept too moist. It is now coming into bloom, likewise P. grandifolius, both 
of which will benefit through having a weak solution of farm-yard manure 
given when in need of water. The latter will grow in almost any pant 
Stove if given a small amount of shade during the summer, but the former 
must have the tempered light of the Phalznopsis house to bea success.
