182 THE ORCHID REVIEW. (JUNE, 1907- 
the collection, the one of O. crispum White Empress, which gained the 
R.H.S. First Diploma last year, having twenty-one very fine pseudobulbs» 
and this was sending up three strong spikes. O. X Coradinei Crawshay- 
anum is a fine plant twelve years old, now carrying two spikes of fifteen. 
and seventeen flowers, three of the latter being on a side branch. 
In this connection we may mention ‘the series of plants in glass pots,. 
which continue to give great satisfaction, and Mr. Crawshay considers that. 
under this treatment the plants can be grown more quickly. The glass. 
pot is of the ordinary shape, with a single hole at the bottom, over which 
a layer of bracken rhizome is placed, the pot then being filled with the: 
usual compost of peat and moss. Owing to the glass being transparent,. 
the moss keeps alive and green, and the roots which work amongst it can 
be seen. A glass pot could have no advantage for ordinary terrestrial plants, 
whose roots work in the dark, but in the case of epiphytes it is different, . 
and it is in the effect of light on the roots, or on the condition of the com- 
post, that the cause of any improvement must be sought. It is now more 
than an experiment, having been tried for years, and the tréatment is being 
extended, so that Mr. Crawshay is satisfied with the result. The question. 
naturally arose, ‘‘ Will the seeds germinate here?’ and the answer was- 
“No,” though they have been blown in through the hole at the bottom 
frequently. It would appear that a more airy position is required for 
germinating seedlings. 
Many beautiful things were in flower, a few of which may be mentioned. 
O. X mulus bore a fine spike of twelve flowers. O. X Andersonianum 
Bogaerdeanum is a very handsome form which was figured at page 305 of 
our fifth volume. There were also some good O. Hallii, O. x Lucasianum,. 
supposed to be a‘natural hybrid between the preceding and O. cristatellum, 
O. triumphans Raymond Crawshay, a good brightly coloured form, O. t+ 
latisepalum, numerous good forms of O. crispum, some good O. xX Adriane, 
a dark O. Hunnewellianum, O. luteopurpureum Mossiz, a very beautiful 
form of the hystrix type, having a white ground to the lip, and others. A 
very large number of plants were pushing spikes. The plant of O. Lindley- 
anum aureum, said to be the only one known, was also pointed out, together 
with O. X Wilckeanum albens, these not being in flower. A very large 
number of spikes were pushing up, a few of them being hybrid seedlings; 
and promised to yield a very fine display of flowers in a few weeks’ time. 
The collection of dried flowers is always interesting, and_ includes: 
nearly everything in the collection, with many others, some of which are 
historical. O.crispum Triomphe de Ramboullet, from the Rutherford col- 
lection, was pointed out as a bad Wilckeanum, and O. x Braeckmani, 
from the collection of M. Metdepenningen, as a form of Adriane. There 
were also flowers from Mr. Leemann, of O. c. Vinicius, constellatum,
