CXXXViii PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 
probably check the spread of this trouble, but affected parts in which 
the resting spores are produced should also be burned. 
Apple Sporting. — Mr. E. A. Bunyard, F.L.S., showed two forms of 
apple from a standard tree of ' Royal Jubilee/ one normal, the other 
russeted and a little smaller. The leaves on the shoots bearing these 
forms respectively were similar to one another, and the flavour was 
approximately the same. 
Scientific Committee, October io, 1916. 
Dr. A. B. Rendle, M.A., F.R.S., in the Chair, and twelve memoers 
present. 
Fungus Gall on Alnus glutinosa. — The Rev. W. Wilks, V.M.H., 
sent a curious reddish gall on the " cones " of Alnus glutinosa, which 
he had found in Scotland. The gall is produced by the growth of 
the fungus A scomyces alnitorquum on some of the bracts, which become 
several times their normal size and project almost like leaves from the 
cones. 
Lychnis from China. — Mr. E. J. Allard showed a Lychnis with large 
flowers somewhat like those of L. Flos-cuculi, but with much longer 
sepals and considerably larger in all its parts, raised from seed sent 
home by Mr. R. Farrer from inland China. It has flowered at Wisley 
and in other gardens, but has not yet been named, and its perennial 
character remains to be proved. 
Variations in Tropaeolums. — Col. H. E. Rawson, C.B., showed some 
specimens of T. tuberosum, which bore entire leaves on one part of 
their growth and more divided leaves in another. This he attributed, 
as with other variations in this and allied species, to differences in 
illumination. He also showed variations in T. majus towards the 
production of divided leaves. He had secured parallel variations in 
flowers and foliage in the two species. 
Crocus from Gunnersbury. — Mr. J. Hudson, V.M.H., showed some 
flowers of a Crocus which he had originally received from Mr. Smith, 
of Newry, as a new species. Mr. Bowles took them to examine further. 
Kniphofia modesta, &c. — Mr. H. J. Elwes, F.R.S., showed a spike 
of this white-flowered plant, which is not quite hardy, and of an 
A eschynanthus, with bright, scarlet flowers, which he had found at an 
elevation of 7,000 feet in Sikkim, growing as an epiphyte. It is appa- 
rently an undescribed species, and might prove hardy in Cornwall. 
Scientific Committee, October 24, 1916. 
Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the Chair, and eight 
members present. 
Sycamore leaf-spot. — Mr. J. Fraser, F.L.S., showed specimens of 
this common disease collected from Ockham Common, Surrey, and
