CCliv PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



Scientific Committee, December 6, 1910. 



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

 seven members present. 



Fruits of Eucalyptus and Allied Plants. — Mr. Worsdell, F.L.S., 

 showed the fruits of Eucalyptus ficifolia, in which they are quite simple ; 

 E. cornutor, where they are partially united; Syncarpia, where they are 

 formed from five or six fused flowers; and Agonis fiexuosa, where they 

 are very densely aggregated. The fruits, which had been collected by 

 Mr. Worsdell in South Africa, showed in an interesting fashion the 

 variation in fruits which may be seen in nearly allied plants. 



Stachys ambigua. — Mr. Eraser, F.L.S., showed specimens of this 

 plant, a hybrid between Stachys sylvatica and S. palustris, and com- 

 mented upon the characters wherein it differed from its parents. 



Kale with Surface Outgrowths. — Mr. Bowles showed a leaf of 

 Scotch kale ffom Mr. Cowan, of Penicuik, with outgrowths from its 

 upper surface, somewhat like those often seen in cabbage, and termed 

 ascidia. In the present case, however, the growths were fringed at their 

 edges and considerably crisped. 



Tar-water and Plants. — Mr. E. Kitley, of Bath, sent two coffee 

 plants, one of which has been watered with tar-water a few times, the 

 other not. The former showed much more vigorous growth, the latter 

 had apparently not been quite equal to the former at the start and had 

 been " stopped." While it is probable that tar-water would have some 

 effect as was shown, tlie Committee thought the particular specimens 

 were hardly comparable with one another. 



Gynura cernua. — Mr. Chittenden showed flowers of this annual com- 

 posite raised from seed received from British Central Africa. 



Scientific Committee, December 20, 1910. 



Mr. E. A. Bowles, M.A., E.L.S., E.E.S.. in the chair, and two 



members present. 



Araucaria Cunninghamii. — An inquiry was received from Mr. Rogers, 

 of Launceston, as to whether shoots of this plant could be rooted. It 

 was pointed out that while this could be done, lateral shoots when rooted 

 rarely formed shapely plants, though shoots from near the top of the 

 tree will do so.
