THE HYBRIDIST. 
ODONTOGLOssUM X LEo.—;Two flowers of a handsome hybrid derived 
from Odontoglossum Hallii ¢ and O. triumphans Lionel Crawshay ¢, are 
sent from the collection of De Barri Crawshay, Esq., Rosefield, Sevenoaks. 
The flowers are fairly intermediate in shape, the sepals and petals being 
much less acuminate than in O. Hallii, while the rich deep yellow and copious 
deep brown blotching most resemble the pollen parent. The very spiny 
crest recalls that organ in O. Hallii, but the shape of the lip is more like O. 
triumphans. The two forms are slightly dissimilar, one of them showing 
rather more of the Halliishape. It is very handsome, and should develop 
into a fine thing when the plants become strong. 
ODoNTOGLOssuM X NeEMEsIs.—Three forms of another hybrid are also 
sent by Mr. Crawshay under the above name. They were obtained from 
O.Coradinei ¢ xX O.triumphans ¢, and are most comparable with O. x 
dicranophorum, Rchb. f., the natural hybrid between O. Lindleyanum and 
O. triumphans. From a decorative standpoint they are rather disappointing, 
having retained too much of the Lindleyanum character, though the flowers 
are considerably enlarged. The sepals and petals are elongated and rather 
narrow, two of them heavily blotched with brown ona yellow ground, while 
the third is only sparsely blotched. The lip is rather narrow, and has a 
long stalk, the colour being yellow blotched with brown, while the column 
is rather long and the wings nearly entire. The hybrid flowered for the first 
time in September, 1906. 
POTTING AND WATERING ORCHIDS. 
AT the usual fortnightly meeting of the Redhill, Reigate and District 
Gardeners’ Mutual Improvement Association, held on Tuesday, April 2nd, 
Mr. W. Seaman in the chair, Mr. W. P. Bound, of Gatton Park Gardens, 
gave a most interesting and instructive lecture on “ Potting and Watering 
Orchids.” Mr. Bound’s ability as an Orchid grower is well known, and 
great interest was centered in the meeting, which was largely attended. 
The lecturer spoke at some length on the use of the Polypodium and 
Osmunda fibre as a potting medium, but as far as his experience with the 
latter was concerned, he could not say very much in its favour. The old- 
timesystem of using a quantity of crocks for drainage had been superseded 
by sterilised rhizomes of fern. The latter not only answered as good 
drainage, but also acted as a food for the plant. The lecturer advocated 
firm potting for well rooted plants, anda good guide when to pot was when 
the roots are being emitted from the collar of the plant. Cattleyas, Lzlias, 
Dendrobiums and Odontoglossums were all dealt with in sectional order 
and at considerable length. A good discussion followed. Mr. W. Rose
