JULY, 1913] THE ORCHID REVIEW. 213 
We now come to the plants themselves, which are estimated to exceed 
ten thousand in number, with a large number of seedlings not yet potted 
off, in fact an extensive series of hybridisation experiments is in progress, a 
few of which we shall be able to mention. Passing from the Corridor into 
the first Cool house we noticed about twenty Odontiodas in flower, together 
with the Cochlioda Neoetzliana parent, among them being the pretty little 
O. Graireana and O. loochristiensis (C. Noetzliana xX O. gloriosum), also a 
few Odontoglossum Clytie (Edwardii x Pescatorei),O. Adrianzeand others, 
with a fine lot of seedlings in various stages, the tiny pots of the smaller 
ones being plunged about thirty together in pans of moss to prevent 
drying of the compost. Among the larger ones a particularly interesting 
batch from O. Edwardii x Miltonia vexillaria was pointed out, and the 
question as to what they would be like can now be answered, for this 
hybrid was described at page 177 under the name of Odontonia brugensis. 
Lath roller-blinds are used as shading, with an additional thir coat of 
whitening for the summer months. We noted also a layer of tobacco 
stalks laid on the hot-water pipes, which is said to be a very effective check 
to thrip. 
The next house contained a very fine lot of Odontoglossums in spike 
and flower, the latter including about thirty good spotted forms of O. 
crispum, a fine O. amabile with clusters of purple spots near the base, and 
many other hybrids, while the magnificent Odontioda Coronation carried a 
spike of fifteen flowers. Here were many seedlings, and all plants were in 
robust health. This house was divided, and in the second half were a lot. 
of typical O. crispum in bloom, with examples of O. Pescatorei, four good 
plants of O, pulchellum, a few O. Rossii, O. Thompsonianum, and a few 
Masdevallias, including M. coccinea, M. ephippium, and a good plant of 
M. Arminii with fourteen flowers. We noted a pan used by M. Lambeau 
which gives excellent results. It contains a central pedestal on which the 
plant stands, and is thus elevated above a small surrounding pool of water 
which helps to keep the plant cool and moist. The pedestal has a hole 
through the centre, so does not obstruct the drainage. 
The next house contained many Miltonias in excellent health, including 
M. vexillaria with a nine-flowered spike, the beautiful varieties G. D. Owen, 
Queen Alexandra and chelseiensis, M. Bleuana, and a self-fertilised form of 
the same, the first of a batch to flower. It is most like M. vexillaria, with 
a rosy basal blotch to the petals, and is very promising. Here also was M. 
Bleuana X M. vexillaria G. D. Owen, the base of the lip being yellow and 
brown without any crimson mask. We further noted Odontonia Firminii, 
from M. vexillaria and an unspotted O. crispum, some large unflowered 
seedlings from O. Pescatorei x M. vexillaria, Cochlioda Neetzliana x M- 
arewices. in spike, young seedlings of Odontioda Charlesworthii x M-
