produced. The Orchids were from the collection of N. C. Cookson, Esq., 

 1 of Oakwood, Wylam-on-Tyne. 



Injury to Apple Tivigs. — Mr. F. J. Baker, A.R.C.Sc, showed some 

 Apple twigs that had heen injured by too tightly binding the shoots 

 together. The shoots had been washed in May with a somewhat strong 

 solution of paraffin, and the result had been that the injuries to the stems 

 appeared very like cankered spots. The wounds were now beginning to 

 callus over. 



Cup-shaped Leaves of Pelargonium. — Mr. W. C. Worsdell, F.L.S., 

 showed some leaves of Pelargonium zonale from Kew which had grown in 

 a cup-shaped manner. Each of these was terminal, a fact that accounted 

 for the form. One of the cup-like leaves bore a second springing from its 

 outer surface. These leaves probably took the place of the flowering shoots, 

 which would have been developed in the same position in a normal season. 



Summer Pruning of Fruit Trees. — A discussion upon this subject 

 took place (see page 487). 



Scientific Committee, October 29, 1907. 

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



Cup-shaped Leaves of Saxifraga. — Mr. W. C. Worsdell, F.L.S., 

 showed leaves of Saxifraga ligulata which had grown in a cup-shaped 

 manner, so that the leaf had the appearance of an inverted cone on 

 the top of the leafstalk. The plant on which they had been produced 

 each year formed similar leaves in October and November, but not in 

 the early part of the year. Not all the leaves were so far developed as to 

 assume the cup-shape completely, but all stages from the normal to this 

 form were to be found. Mr. Worsdell suggested that the cause of the 

 malformation might have been the lack of vigour in the plants. 



Malformed Cattleya. — Mr. Eennett-Poe, V.M.H., showed two flowers 

 of Cattleya labiata, each of which had but two petals and two sepals, 

 the labellum in each case being completely suppressed as well as one of 

 the sepals. Mr. Worsdell took the flowers for further examination. 



Calycanthus Fruits. — Mr. Bowles showed fruits of Calycanthus 

 occidentalis from his garden for comparison with those of C. laevigatus 

 shown at the meeting on October 1 (p. elxviii). 



Marrow Cabbage. — Messrs. Cooper, Taber & Co. sent specimens of 

 the Marrow Cabbage (' Chou Mcellier ') grown at Witham, Essex. The 

 Cabbages were about 5 feet in height, the stem being between 4 inches 

 and 5 inches in diameter in the middle. The central part of the stem is 

 filled with soft tissue, and forms the chief edible portion of the plant. 

 The Cabbage is grown largely in France, where it is pulped and used for 

 cattle food in districts where Swedes and Turnips will not grow. It is an 

 exceedingly interesting example of a variation of the Cabbage, where 

 the reserve food is stored in an elongated, thickened stem instead of in a 

 barrel-shaped stem, as in Kohl Eabi. 



Kale with Leaflike Growth from Midrib. — W. J. Maitland, Esq., of 

 Witley, sent leaves of a purple Kale having leaflike outgrowths from the
