times to grow it from seeds and from cuttings he had at last succeeded. 

 On the motion of Mr. R. Hooper Pearson, seconded by Mr. W. Hales, 

 a Botanical Certificate was unanimously recommended to the plant. 



Fasciated Polyanthus. — Mrs. J. R. Randolph sent a remarkable 

 example of fasciated Polyanthus, the flower-stem of which measured 

 over an inch in diameter. 



Lysichitum camtschatcense. — Lady Turner sent from Haslemere 

 flowering specimens of this fine herbaceous plant growing unprotected 

 outdoors and flowering well. This plant is rarely seen, but is one of 

 the finest of the hardy Aroids (fig. 91). 



Scientific Committee, June 8, 1915. 



Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the Chair, with sixteen 



members present. 



Uncommon Plants. — Mr. J. Spencer Evans, of Newbury, sent a 

 plant identified by Dr. Rendle as Erigeron uniflorns, raised from seed 

 from Tierra del Fuego. The plant is of wide distribution in Arctic 

 regions. Mr. T. Hay, superintendent of Greenwich Park, sent Phacelia 

 concinna raised from seed from Punta Arenas, Patagonia. Lady 

 Lawrence sent the interesting and beautiful Conanthera campanulata, 

 a plant introduced long ago, but rarely seen in gardens. It is a native 

 of Chile, growing in grassy places near the snow-line. A Botanical 

 Certificate was unanimously recommended to the last-named plant. 



Flowering Time in Different Latitudes. — Mr. J. Fraser, F.L.S., 

 showed specimens of Salix nigricans and the hybrid S. arbuscula x 

 herhacea from his own garden and from their Scotch habitat, to illustrate 

 the enoimous difference in growth in the two localities (the foliage 

 produced in the former being far larger than in the latter), and the 

 difference in time of flowering, both forms flowering about two months 

 earlier in the southern than in the northern habitat, which was at 

 an elevation of about 2,100 feet. 



Apple Fruit Spot. — Dr. A. S. Home exhibited shrivelled mummified 

 apples, which in October had shown numerous small brown spots 

 extending just beneath the skin and generally slightly depressed, 

 but no definite fungus growth. They now bore numerous pycnidia 

 of Cylindrosporium Pomi, a fungus described by C. Brooks (Bull. Ton. 

 Bot. Club, 35, 1908, p. 423), as the cause of a serious fruit spot of 

 apples in the United States, but not previously recorded definitely 

 for this country, though its presence has been suspected from the 

 symptoms produced. 



Apple Shoots Dying. — Mr. E. M. Holmes, F.L.S., showed shoots 

 of Apple with canker-like spots, and with the newly-formed growths 

 dying back, which Mr. G. Massee recognized as due to the attack 

 of the fungus Sclerotinia fructigena. 



Aliens. — Mr. Holmes also showed specimens of Sideritis lanata,
