SCIENTIFIC COMMITTEE, FEBRUARY 20.

Dr. K. Schilberszky. ' " In reference to the foregoing, Mr. A. S. 

 Horne wrote: — " It is interesting to find that Professor Schilberszky 

 has identified the disease which was recorded by Mr. Giissow, in New- 

 foundland, as that described by himself in potatos derived from Upper 

 Hungary. There were two points at issue in Britain, concerned both 

 with the disease and the organism : (1) Professor Schilberszky stated 

 in his published description that crater-like depressions were formed in 

 some tubers. Symptoms of this kind were not found in potato 

 tumour in this country. (2) At first spores of only one kind were 

 found in this country. It is a well-known fact that tumours of a 

 similar form may be caused by different organisms. There was con- 

 fusion between the tumour in beetroot, caused by Urophlyctis 

 leproides, and potato tumour. It was possible, therefore, that the 

 tumour in the British disease might have been due to a different 

 organism, or perhaps to more than one organism. For these reasons 

 investigators in England desired the personal assurance of Professor 

 Schilberszky that potato tumour was due to his Chrysophlyctis endo- 

 hiotica." 



Scientific Committee, February 20, 1912. 



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



members present. 



Oncoha Routledgei. — Mr. Shea remarked, with reference to seed- 

 lings of this plant, that of seventeen raised by him from one fruit, 

 fifteen were spiny and two quite without spines (see Journal E.H.S., 

 xxxvii. pp. xxxiv, li, cxiv). 



Coelogyne venusta. — Sir Frederick Moore, Glasnevin, sent an 

 inflorescence of this interesting species. It is a native of Yunnan. 

 On the motion of Mr. O'Brien, V.M.H., seconded by Mr. Shea, it was 

 unanimously resolved to recommend the award of a Botanical Cer- 

 tificate to it. 



Violets with branched peduncles. — Miss Dalton sent from Sway, 

 Hants, a number oi Violets bearing branched peduncles, and appar- 

 ently more or less fasciated. They had been cultivated in the ordinary 

 way, but in some two or three specimens two flowers were pro- 

 duced at the apex of the common peduncle; in others the peduncles 

 separated lower down. Several examples of a similar nature have 

 been sent to the Committee during the present season from widely 

 separated localities ; otherwise it appears that violets are but rarely 

 fasciated. 



New Orange. — Mr. H. S. Elvers sent a variety of Orange newly 

 introduced, known as 'Ooushin,'* ' Satsuma,' and * Kii Seedless.' 

 It is a Japanese variety somewhat like a Mandarin. The somewhat 

 flat fruits shown were from maidens, and the variety is said to be 

 almost hardy, ripening its fruit very early. The skin is thin and 

 deep yeUow; the flesh juicy, sweet, and well flavoured; quite seedless.
