Mooreana, Cymbidium insigne, Pleione yunnanensis, Oncidium Clesii, 
Cypripedium tibeticum, and two interesting Cattleyas, C. Jenmanii and C, 
Forgetiana. Hybrids were again numerous, and included two additional 
Odontiodas, heatonensis and Bohnhofie, a generic hybrid in Brasso- 
epidendrum stamfordiense, Ceelogyne Brymerianum, the first hybrid in the 
genus, several beautiful Odontoglossums, and numerous additions to the 
familiar genera. 
The novelties of 1907 were chiefly of hybrid origin, and included 
Odontioda Bradshawie, a striking hybrid between Cochlioda Neetzliana 
and Odontoglossum crispum, and Odontioda Devosiana, the corresponding 
hybrid with Odontoglossum Edwardii, both of which gained First-class 
Certificates from the R.H.S. Odontonia Elwoodii was an interesting 
generic hybrid between Miltonia Roezliit and Odontoglossum cirrhosum, and 
there were over a dozen additions to the genus Odontoglossum, besides 
some seediing forms of O. crispum. Odontoglossum was now falling 
into line with the other popular genera, among which latter there was the 
usual crop of interesting novelties. 
(To be concluded). 
Root Funct oF Orcuips.—In the January issue of the Orchid Review 
(p. 4) I notice a summary by Miss Chevely Rayner on the Endophytic 
Mycorhiza of Orchids, and I observe the phrase: ‘‘ Bernard demonstrated 
the impossibility of raising uninfected seedlings.” This is a mistake. 
During the last years of his life my friend, M. Noel Bernard, obtained the 
germination of seeds of Phalenopsis Sanderiana XX rosea in an aseptic 
tube. He sent some of the seedlings to me. I still possess one of these 
plants, and it is perfectly developed, and flowers regularly every year. 
Therefore we have obtained seedling Orchids without the employment of 
the Rhizoctonia. Daring the last years of his life M. Bernard thought 
the theory would have to be revised. 
In the same way, M. Constantin, in his last work, La vie des Orchidées, 
hopes by the employment of different endophytes to effect a change in the 
morphological character of the plants. I have communicated an experience 
to M. Bernard which gave negative results. Seeds were obtained of Leelio- 
Cattleya Mozart x Brassavola Digbyana, and seedlings were raised by 
infection with the Rhizoctonia of a Cypripedium, but they presented no 
anomalous characters consonant with this theory. It is indisputable that 
germination is facilitated by the Rhizoctonia, but not that they cannot be 
germinated in their absence.—F. Denis, Balaruc les Bains, Hérault, 
France. 
It would be interesting to know if the Rhizoctonia is really absent from 
the roots ofthe Phalzenopsis.—Ep.
