XXXii PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 
Scientific Committee, April ii, 1917. 
Mr. W. Hales, A.L.S., in the Chair, and three members present. 
Fasciated Rose. — Mr. J. Fraser, F.L.S., showed shoots of a Rose 
very much fasciated towards the top, and, as often happens, cylindrical 
at the base. 
Chlorosis in Fagus sylvatica. — He also exhibited shoots of Beech 
which he had collected on a chalk hill in which all the leaves were 
yellow, and remarked upon the frequency of the occurrence of chlorosis 
in plants growing in chalky soil. The disease appears to be due to 
insufficiency of iron, and is usually curable by the addition of iron 
sulphate to the soil. 
Apple Bark Splitting. — Mr. F. J. Baker, A.R.C.S., showed specimens 
of Apple shoots in which, during the past winter, longitudinal splits 
in the bark had appeared. The splitting has occurred in many places, 
and is probably due to severe frosts. The branches exhibited had 
evidently been taken from trees growing in a wet soil. 
Scientific Committee, April 24, 1917. 
Mr. E. A. Bowles, M.A.,F.L.S., F.E.S.,in the Chair, and six members 
present. 
Forms of Agrostis alba. — Mr. J. Fraser, F.L.S., showed a series of 
specimens of forms of Agrostis alba from various localities, illustrating 
the wide range of variation which this species exhibits in its range 
from seashore to wet pasture lands. 
Primula stenocalyx.— Mr. Bowles showed specimens of the two 
forms of this Chinese species, the one with, the other without, scent. 
Mr. Farrer has given an account of the two in his report of his Chines.e 
journeys. He also showed flowers of the form called Primula Loczii, 
nearly related to P. farinosa, but forming stolons and several plants 
around the parent one. 
American Gooseberry Mildew.— The following note on observations 
made by Mrs. E. V. Horne at the R.H.S. Laboratory at Wisley on 
the effect of Burgundy mixture on the winter fruits of the American 
Gooseberry mildew was read : — 
" During the late autumn and winter I collected and examined 
a large number of twigs from Gooseberry bushes affected with the 
American Gooseberry mildew at Wisley, which had been sprayed with 
Burgundy mixture by Dr. Horne in July 1916, with the object of 
discovering whether the spraying had destroyed the vitality of the 
perithecia (winter fruits). 
" Spraying was done after mature winter fruits had formed on 
a large number of the twigs. Prior to the spraying, several twigs
