XXXii PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



grown and fruited but poorly. Mr. Massee, V.M.H., recognized the 

 disease as due to the attack of the fungus Hendersonia ruhi. 



Scientific Committee, Febeuaey 6, 1912. 



Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the Chair, and ten 



members present. 



Abnormal Cattleya. — Mr. Manda, of St. Albans, sent a Cattleya 

 bearing several flowers, every one of which was abnormal, some much 

 more markedly than others. 



Castasetum Randii. — Mr. Eolfe, A.L.S., drew aittention to a 

 Catasetum shown by Messrs. Charlesworth, which he recognized as 

 Catasetmn Randii, Eolfe {Bot. Mag. t. 7470, where both male and 

 female flowws are shown). This species differs from G. harhatum and 

 its few allies in having the crest of the lip shortly truncate and broken 

 up into many short filaments, not forming a single horn-like tooth. It 

 is a native of the Amazons. 



Floral drawings. — Miss Massee showed some excellent coloured 

 drawings of various types of plants, faithfully coloured and showing 

 dissections of the essential parts very clearly. 



New Hippeastru7ii. — Mr. Worsley showed a new Hippeastrum, 

 for which he proposed the name of Hippeastrum Forgetii in honour of 

 the collector. The bulbs had been received by Messrs. Sander from 

 Monsieur Forget, their collector in Bolivia, and the plant is closely 

 allied to H. pardinum, but without spots. A full description appears 

 at p. 73. 



Chrysophlyctis endohiotica. — Mr. H. T. Giissow, of the Central 

 Experiment Farm, Ottawa, wrote: — "From Mr. Home's paper on 

 ' Tumour and Canker in the Potato ' in the Society's last Joubnal 

 we may conclude that all efforts to secure confirmation of the identity 

 of the Potato disease with Schilberszky's from the discoverer himself 

 were futile, and that ' it is necessary, therefore, to rely upon Schil- 

 berszky's original, somewhat meagre, description.' Early in 1905 

 I wrote to Professor Schilberszky, submitting a diseased tuber to him, 

 but received no reply. Again in 1909, when I discovered the disease in 

 Newfoundland, I wrote to Professor Schilberszky, and received a letter 

 from him, which I very carefully kept. The following is a transla- 

 tion : — 'Budapest, 12 March, 1910. I have the honour to inform 

 you that I have already sent you a little time ago a statement regard- 

 ing the Potato tuber which you sent me. I am now appealed to by 

 Dr. V. Degan to write you again in the same connexion. I beg to 

 inform you that the Potato tuber was infected by Chrysophlyctis 

 endohiotica. The diseased portions alone made the identification very 

 easy by their external characteristic appearance. I may say that in 

 one of the infected foci I found masses of bacteria, which I have not 

 examined any closer. It would interest me to have your observations 

 on the spread of this disease in your country. — (Signed) Professor
