FEBRUARY, 1903.] THE ORCHID REVIEW. 37 
also two from B. glauca, namely, Brassocattleya xX Orpheus and 
Brassolzlia X Clio. Lelio-cattleya xX Choletiana and Lelia X Nemesis 
are two interesting hybrids from Lelia superbiens. M. Ch. Vuylsteke 
has added to his former triumphs by flowering Odontoglossum x bellatulum, 
O. X Vuylstekei, and four forms of O. X armainvillierense, of which the 
superb O. X a. ardentissimum was figured at page 209 of our last volume, 
while O. X Queen Alexandra flowered in the collection of J. Rutherford, 
Esq. Other interesting novelties are Sophrolelia x heatonensis, S.-l. x 
Psyche, Dendrobium xX Ophir, D. X Hunteri, the first hybrid from D. 
Brymerianum, Zygopetalum X Roeblingianum, Epilelia x Sylvia, Lelio- 
cattleya X Queen Alexandra, L.-c. xX Ira, the first hybrid from Lelia 
longipes, L.-c. x Hodgkinsone, and various other Lelio-cattleyas, 
Cattleyas and Paphiopedilums, which represent substantial progress in this 
department. 
CERTIFICATED ORCHIDS. 
The number of First-class Certificates awarded by the Royal 
Horticultural Society is again in excess of the previous year, forty plants 
having gained this distinction during 1902, namely, thirteen Odonto- 
glossums, six Leelio-cattleyas, five Cattleyas, four Paphiopedilums, three 
Brassocattleyas, two Lelias, and one each of Brassolelia, Miltonia, 
Oncidium, Phaleznopsis, Sophrolelia, Zygocolax, and Zygopetalum. It is 
a significant fact that over half these plants are hybrids of artificial origin, 
and six others are natural hybrids. The plants which received Awards of 
Merit are still more numerous, but these and the numerous Certificated 
plants of the Manchester Orchid Society must be passed over. : 
Usr oF LEAF-MOULD. 
The use of leaf-mould as an ingredient in the potting compost for 
Orchids has largely increased during the year, and many growers have 
expressed their satisfaction with the results. It seems to be generally 
agreed that if judiciously mixed with other ingredients, so as to insure the 
right mechanical condition of the compost, it will be an invaluable adjunct 
to Orchid culture. 
SEEDLING ODONTOGLOSSUMS. 
Seedling Odontoglossums have come to the front during the past year 
in a way which suggests that the difficulties formerly encountered in raising 
these plants have now been overcome. Besides those which were exhibited 
in flower at the Temple Show, and which have already been mentioned, we 
have the remarkable batch of six hundred seedlings in the collection of W. 
Thompson, Esq., of which we are now able to give an illustration (page 41), 
and we know that they are being successfully raised in some other collec- 
tions. This circumstance is likely to give an additional stimulus to the 
cultivation of these beautiful plants.
