176 THE ORCHID REVIEW. [JUNE, 1915 
press the compost down with moderate firmness and leave sufficient space 
below the rim of the pot to contain a quantity of water, for the plants will 
require abundant supplies after they have become thoroughly well rooted. 
Place them in a cool, shady position in the Intermediate house, and until 
new roots become plentiful afford water to each plant with great care. If 
large quantities of water be given before the plants become properly 
established in the new compost, the old roots will be sure to decay 
prematurely, the new growths become weakly and damp off, and the young 
foliage become spotted. Keep their surroundings moderately moist at all 
times. This may be done by damping well between the pots several times 
daily. 
Other Cymbidiums that are not so well known as those previously 
mentioned, and which will grow under similar conditions are C. longifolium, 
ensifolium, aloifolium, chloranthum, pendulum, madidum, ‘and many 
others. . C. (Cyperorchis) affine, and C. elegans may also be included. 
C. Devonianum is quite a distinct species, especially as regards its flower 
spikes, which are pendulous, and, being of dwarf habit, the plant should be 
elevated well up to the roof glass. C. tigrinum is also a dwarf-growing 
species. It prefers the Cool house in summer, but in winter should be 
removed to the Intermediate division. 
Coot House.—lIn this house many plants are in flower at present, 
including the useful Odontoglossum crispum, and its numerous varieties 
and hybrids; also many Odontiodas, Cochliodas, Oncidiodas, &c., &e. 
For the present it is advisable not to damp down too frequently or too 
heavily, as the flowers would be liable to become spotted and useless. . A 
moderate damping at early morning, when the weather is fine, and in the 
evening will be sufficient, leaving the ventilators open both at top and 
bottom. When the flower spikes have been removed the plants will not 
require nearly so much water at the roots, but while at rest the pseudo- 
bulbs should not be allowed to shrivel unduly for want of water, although 
a slight shrinkage will do them no harm. 
Opurys KELLERI.—A new hybrid Ophrys is described and figured by 
Col. M. J. Godfrey in the May issue of the Journal of Botany (p. 121, t- 538). 
It was found on March 24th, 1914, among a small colony of Ophrys arach- 
nitiformis on a thinly wooded hillside of the Mont des Oiseaux, at Hyeres- 
It is suggested as a hybrid between this species and O. atrata, as it possesses 
intermediate characters, and the latter is frequent in the neighbourhood. 
It is named in honour of Dr. G. Keller, of Aarau, Switzerland, who 15 
preparing an illustrated work on the Orchids of Europe. The plate also 
contains > figure of O. olbiensis, Camus, a hybrid between O. bombylifiora 
and O. Scolopax.
