Acorns with two or three radicles. — Mr. E. M. Holmes, F.L.S., 

 showed some Acorns with two or three radicles. The embryos of 

 which they formed part were not, however, fully developed. 



Daphne odora.—Dr. Otto Stapf, F.E.S., drew attention to the 

 fact that most of the figures in botanical works under this name 

 represented Daphne sinensis, the true D. odora being very rarely 

 figured, and apparently only of comparatively recent introduction into 

 this country. In times past, at any rate, it would appear that 

 2). sinensis was the more common plant. It differed from D. odora, 

 a Japanese species, in having the calyx tube externally hairy. Messrs. 

 J. Veitch exhibited the true D. odora at the Show on this day. 

 Dr. Stapf showed a figure from the Garden, which was named 

 D. odora, but which differed markedly from that species in the 

 arrangement of its flowers. 



Yucca with curious outgrowths. — Mr. Bowles showed leaves of 

 Yucca filamentosa flaccida from his garden, with curious, short, hollow, 

 horn-like lateral growths near the top of the leaves. He had seen the 

 same thing in the same variety in the gardens of Trinity College, 

 Dublin, and all the plants of this variety, but of this variety only, 

 showed the peculiarity in his garden every season. 



Ruscus aculeatus. — Mr. Bowles showed from a garden in Cam- 

 bridgeshire a branch of Ruscus aculeatus bearing an extraordinary 

 quantity of ripe berries. He took it for further examination. 



Scientific Committee, Januaey 23, 1912. 



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



members present. 



Ruscus aculeatus .—Ml . Bowles had examined the flowers on the 

 fruiting branch of Ruscus aculeatus shown at the last meeting and 

 found they were all male. He showed various forms, including a dwarf 

 form from Wales with hermaphrodite flowers, the common tall form, a 

 close-growing form collected by Mr. Paul in Epping Forest, and one 

 with blue-green cladodes of still dwarf er form. The var. angustifolius, 

 a variety with very narrow cladodes and bearing pistillate flowers, a 

 rather stiffly-growing variety with somewhat broader cladodes, and one 

 with very loose growth and very broad cladodes were also shown. Mr. 

 Hales said the flowers of Ruscus Androgynus were variable in the 

 same way as those of R. aculeatus. 



Galanthus Elwesii var. poculiformis. — Mr. Bowles also showed a 

 flower of this beautiful and robust Snowdrop, the inner segments 

 being white without the green marks usual in Snowdrops. 



Nandina domestica fruiting. — Mr. Fox, of Carmino, Falmouth, 

 reported the fruiting oi Nandina domestica in his garden in 1911. 



Raspberry canes diseased. — Mr. Peters, of Eipley, sent canes of 

 Raspberries showing whitish patches on the skin with tiny black 

 spots upon them. Many canes had died, and others attacked had
