XXXii PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



SCIENTIFIC COMMITTEE. 



January 14, 1919. 

 Mr. E. A. Bowles, M.A., V.M.H., in the Chair, and five members present. 



Bulbils in Leek Inflorescence. — Mr. W. Cuthbertson showed a large inflorescence 

 of the common Leek in which each of the flowers was replaced by one or more 

 bulbils, as is frequent in many species of Allium. Mr. Cuthbertson, in a long 

 experience, had never met with a similar case. 



Substitute for Caraway seed. — Mr. Bowles showed seed of Dill, which is being 

 used as a substitute for Caraway seed. In the opinion of the Committee there 

 seems no reason why Caraway seeds should not be grown in England to supply 

 all our requirements. 



Fruits from Salonika. — Mr. Bowles also showed fruits of an Asclepiadaceous 

 plant, which Mr. W. C. Worsdell took for identification. 



Primula Juliae hybrid. — Mr. Rosenheim sent a fine-flowered hybrid of 

 Primula Juliae, winch had occurred in his garden, and which he thought might 

 be a hybrid with P. leucophylla. 



Scientific Committee, January 2S, 1919. 

 Mr. E. A. Bowles, M.A., V.M.H., in the Chair, and five members present. 



Fruits from Salonika. — Mr. W. C. Worsdell, F.L.S., reported that he had 

 compared the fruits shown by Mr. Bowles at the last meeting with herbarium 

 specimens, and had identified them as Marsdenia erecta and Periploca graeca. 



Flowers as aids to identification in Apple. — Mr. C. H. Hooper, F.S.I., drew 

 attention to a series of photographs of Apple stamens and styles made in Victoria, 

 Australia, and published in the Journal of the Dep. of Agr. for Victoria, and 

 remarked upon the great range of variation in arrangement and form exhibited. 

 Unfortunately not all the flowers had been photographed at the same stage 

 of development, but there can be no doubt that floral details may be a great 

 aid in the identification of Apple varieties, and also in all probability to their 

 classification. 



Rogues in Beet. — Mr. F. J. Baker, A.R.C.S., drew attention to the presence 

 of long, fangy roots of a white colour in a crop of Beets grown from home-saved 

 seed of a particularly good stock of Globe Beets in an allotment garden. It 

 had been suggested that the result was due to crossing with Spinach, but it 

 seems more likely that crossing with either Mangolds or some other variety of 

 Beet had occurred, for it is well known that crossing readily occurs among 

 Beets unless they are separated by very long distances. It is, of course, possible 

 that segregation in the F 2 generation was occurring. 



Pritzel Committee. — Mr. Bowles announced that the Council were about to 

 appoint an official representative of the Scientific Committee to act upon the 

 Pritzel Committee, and the name of Dr. A. B. Rendle, F.R.S., was suggested 

 and unanimously approved. Dr. Rendle is now Professor of Botany to the 

 Society. 



Erythraea scilloides. — Mr. T. B. Rhys, of Tenby, wrote saying that he had 

 discovered Erythraea scilloides growing wild in north Pembrokeshire. It had 

 been identified at the British Museum and had never previously been recorded 

 as wild in the British Isles. 



Scientific Committee, February ex, 19 19. 



Mr. E. A. Bowles, M.A., V.M.H., in the Chair, and four members present. 



Nectria cinnabarina. — Mr. E. A. Bowles showed a branch of an Acer covered 

 with the numerous coral spots produced by this fungus in its fruiting stage. 

 The fungus is exceedingly common on a variety of woody plants. It is a wound 

 parasite, invading and killing the healthy tissue about the wound, and not 

 producing its fruit until it has" killed the wood invaded. The treatment consists
