open properly, but split across one or more of the petals, while in others the edges 
of the petals were damaged. It would be of interest to learn whether other 
species besides regale and sulphur eum are attacked by ants in this manner. 
Raspberry Canker. — Some canes of Raspberry attacked by a species of 
Coniothyrium allied to or identical with the one which causes canker in Roses 
came from Mr. Beresford, of Prestbury, Cheshire. The bark was split and a 
considerable amount of corrugated growth had developed on the edges of the 
wounds. This growth was soft in character, and had dried up to some extent 
in the specimens sent. A similar complaint had occurred some years ago on 
Chinese Brambles at Wisley, but had not spread, so that cutting out the diseased 
canes will probably prove an effective check upon the disease. 
Scientific Committee, August 28, 191 7. 
Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the Chair, and five members 
present. 
The late Mr. Charles Druery. — A letter was received from Mr. T. Murray 
acknowledging the vote of condolence to the relatives of the late Mr. Charles 
Druery. 
Plumose form of Plantago major. — Mr. Bowles exhibited the plumose form 
of Plantago major similar to that figured in Gerard's Herbal. 
Hybrid Campanulas. — Mr. T. B. Grove sent the following notes on the crossing 
of Campanulas, illustrating them with an interesting series of nature-printed 
figures of the crosses obtained. 
Comparison of Fi Seedlings and the effect of the $ . 
" Camp, carpaiica ' White Star ' $ x Tommassiniana $ produced nineteen 
seedlings Zi to Z19, all similar in growth and foliage, viz. intermediate 
between the two parents, and all had uniform blue flowers, only varying slightly 
in size and in vigour, but all partook more in branched habit, and foliage of the 
$ than otherwise. I cannot show prints of this series as I only have about half 
a dozen varieties left of the nineteen. 
" During 1915 I crossed : 
" Firstly, Zi (' Norman Grove ') $ x Waldsteiniana $ and obtained six seedlings. 
"Secondly, Zi £ x Tommassiniana $ and obtained thirteen seedlings. Note 
the $ the same as in Zi. 
" Thirdly, Z 1 S. 47 ('Wyndley Purple ') $ x Waldsteiniana $ and obtained 
two seedlings. 
" The first series of six all showed the effect of the $ in the small foliage 
and erect blooms and habit of flower. 
'y It will be seen from the prints that all are similar to the $ in foliage, with 
a decided likeness to the same variety in habit of growth, and in every in- 
stance have erect flowers like to Waldsteiniana. 
" The second produced thirteen seedlings of which two have not flowered, but 
the eleven which have, have all produced blue flowers, eight medium, two darker 
than type, and one very pale. All are more or less pendant in flower, and most 
of them show a tendency to the bunched habit of the $ — in fact, the whole series 
show a greater similarity in their" growth and general appearance to the pollen 
parent, although in this case it has not been attended with the lanceolate form 
of foliage of Tommassiniana. 
" The third cross produced two seedlings, both of which have rich purple- 
coloured flowers, are both erect in habit of flowering and dwarf in growth like the 
$ , and although the foliage is not so small as that variety, the leaves seem to set 
themselves erect and stiff, more like the $ than the $ . The No. 2 seedling 
is the more compact, and will make a grand front line variety. 
" During 1 91 6 I crossed a large pure white Fi seedling of Z8 x ' White Star ' 
No. 2 (Z8 is brother to ' Norman Grove,' and which has proved to be a 'White 
Riverslea ') with pollen of Waldsteiniana. on one bloom and with pollen of Tom- 
massiniana on another bloom of the same spike of flower, and from these two 
seed pods I have two series of plants which show the effect of the $ in a very 
marked degree. 
"The Tommassiniana seedlings again are in the majority, as I have about 
sixty, of which half have flowered, and all of which show a great similarity to the 
first seedlings from ' White Star ' x Tommassiniana, being uniform in colour and 
pendant in bloom.
