16 THE ORCHID REVIEW. [JANUARY, 1913+ 
though all came yellow, they were not uniform in character. Flowers of 
five seedlings had been picked out and sent to him, no two of which were. 
alike, and in one the spots were distinctly more marked than in the original,. 
while another was pure yellow, as pure as C. insigne Gladys, and he could 
not detect a speck of brown or a coloured hair anywhere. Reversion as the 
result of crossing was not remarkable, for lost or latent characters might 
easily be revived. A plant might be regarded as made up of a host of 
characters, which had been successively acquired, and some of these were 
evidently very ancient. while others were geologically recent. In the course 
of evolution new characters were constantly arising. In conclusion he 
appealed to all those who were making experiments to send the results. to 
the press, as by so doing a mass of evidence would be accumulated that 
would be of the greatest value to Orchidists. 
Major Hurst remarked that the white of Orchids was not white in the 
sense of a combination of the colour of the spectrum, but rather. the 
absence of colour, and attempted to explain that colour in Cattleya and 
Cypripedium was due to the simultaneous presence of two-colour factors, 
and the absence of either of them, as well as of both, would result in albinism. 
Messrs. J. Fraser, W. H. Hatcher, J. M. Black, W. Bateson, and de Barri 
Crawshay also spoke. 
The Chairman, on behalf of the Conference, tendered a cordial vote of 
thanks to the lecturers and all who had helped to make the meeting a 
success, and Sir George L. Holford, in proposing a vote of thanks to the 
Chairman, said that all the skill in the world would not grow Orchids to 
perfection without proper glass accommodation, and failures were oftem 
due to bad housing and bad positions rather than to the want of care on 
behalf of the grower. 
PHALZNOPSIS INTERMEDIA PorteI.—The Hon. Walter Rothschild 
states that, after five years resting, the large plant of Phalenopsis 
intermedia Portei, which has been at Tring Park for over thirty years, has 
again flowered. It produced this year three large-branched spikes, with a 
total of 185 flowers and fully-developed buds. The largest spike has 13 
branches with 84 flowers and buds, the next largest 7 branches with 61 
flowers and buds, and the smallest 5 branches with 40 flowers and buds. 
The plant was among an importation of Phalaenopsis Aphrodite sent home 
by Boxali to Messrs. Hugh Low & Co., some 32 years ago (Gard. Chron., 
1912, ll. p. 453). One of the spikes was exhibited at the R.H.S. meeting 
held on December 17th !ast, and was awarded a Lindley Medal. _ P. inter- 
media originally appeared in an importation of P. Aphrodite (P. amabilis, 
Lindl.) with Messrs. James Veitch & Sons, and was described by Lindley as. 
a natural hybrid between the latter and P. rosea.
