284 THE. ORCHID REVIEW. 
pediums. I find Odontoglossum crispum grows very well in it in this 
climate. My modus operandi for cool Orchids is as follows:—We have all 
the rhizome extracted this is essential—and. then place two-thirds 
sphagnum to one-third Polypodium fibre, and pass it through a chaff- 
cutting machine. This cuts the mixture up very fine, and we use it as it 
leaves the cutter. I know the Continental firms use it also for Cattleyas 
and Lzelias, but whether it has any advantage over good peat I have much 
doubt. My friend, Dr. Foulis of Edinburgh, on my advice, potted all his 
warm Orchids in it, and with most disastrous results, as it produced fungus 
and destroyed all their roots. I hope he may write you his experience on 
the subject—as well as others who have tried it. When once the fungus 
has disappeared, plants seem to do very well init. I may add that I have 
some four thousand imported crispums potted up in it this year, and they 
are doing as well as_I could possibly wish. R. BRrooMAN WHITE.

ORCHIDS AT THE ROYAL HORTICULTURAL 
SOCIETY. 
THERE was a very good show of Orchids at the Drill Hall, James Street, 
Westminster, at the Royal Horticultural Society’s meeting on July 24th, 
and many of the exhibits were of great merit. 
_ The Right.Hon. Lord Rothschild, Tring Park (gr. Mr. E. Hill), sent 
spikes of two magnificent forms of Cattleya x Hardyana. The first was 
labelled Tring Park variety, but is extremely near the original typical form. 
It was a splendid inflorescence of five flowers, and received both a First- 
class Certificate and a Cultural Commendation. The other was the variety 
laversinensis, a two-flowered inflorescence, with blooms of great size, the 
sepals and petals beautifully mottled with rose and white, and the lip dark 
and very richly coloured. It also received a First-class Certificate. 
T. Statter, Esq., Stand Hall, Whitefield, Manchester (gr. Mr. R. Johnson), 
exhibited Cattleya granulosa superba, a three-flowered inflorescence of a 
very fine variety, with much white on.the margin of the lip, which received 
an Award of Merit, and Cattleya Warscewiczii regalis. 
» Major Joicey, Sunningdale Park (gr. Mr. Thorne), showed a plant of 
Cattleya Warscewiczii, with an inflorescence of six magnificent flowers, and 
a fine plant of Anguloa Ruckeri with ten flowers, a Cultural Commendation 
being awarded to the latter. 
- FB. W. Moore, Esgq., Royal Botanic Garden, Dublia, sent flowers of 
Bilrenaria —— =e nee tne a Bollea Lalindei, the singular Gongora 
di , and Dendrobium ciliatum, the 
latter receiving a Betesical Certificate.
