REPORT FOR 1910. 
569 
Senecio vulgaris, L., var. lanuginosus (Trow). St, Oueii’s, 
Jersey, 3999. Quite the prevailing form about the Quenvais and on 
cliffs at Petit Bo, Guernsey. It is radiate. — G. Claridge Druce. 
Excellent specimens. I can see no good grounds for ranking this 
as a species, and agree with Mr. Druce in considering it a well- 
marked variety, subject to the test of cultivation. — Edward S. 
Marshall. When testing the constancy of varieties from seed, 
it is important to remember that some plants, e.g., most Ilieracia, 
produce seeds without pollination in a vegetative manner. Such 
plants will always be constant, just like plants reproduced in any 
other vegetative manner. — C. E. Moss. 
Senecio squaiidus, Linn. Ballast mounds, Witton Brook, 
Northwich, v.-c. 58, August 1910. — W. Hodge. Yes, the type with 
liairy achenes. — G. Claridge Druce. 
Senecio squaiidus, L. Seedlings, Oxford, July 1910. Locally, 
a very aggressive species in bare loose soil.— G. Claridge Druce. 
Senecio [squaiidus X vulgaris\ Near Town Hall, Cardiff, v.-c. 
41, August 23, 1910. d'his grew with Senecio squaiidus and S. 
vulgaris, var. radiatus, which no doubt are the parents. Not only 
the general appearance, but also the foliage, and most of all the 
shape of the anthode, hybridity. I have often seen probable 
hybrids of the two species about Cardiff, but never such a likely- 
looking form as this. I am sorry that the supply is small. — H. J. 
Riddelsdell. I think this is not a hybrid, but a state of squaiidus. 
'bhe specimens are side shoots from an old stock and therefore 
scarcely typical. The basal rosette and the main axis should if 
possible be sent. These plants about Cardiff are very puzzling. 
A specimen which I transferred to my own garden because I sus- 
pected it to be of this hybrid origin, proved to be a form of Senecio 
Jacobcea I — A. H. Trow. I see no evidence of S. vulgaris .- — 
G. Claridge Druce. My specimens look quite right, and excellent 
intermediates. Was the gathering a mixed one? — Edward S. 
Marshall. 
Senecio squaiidus X vulgaris ? = S. Baxterii, Druce. Ballast 
mounds, Witton Brook, Northwich, v.-c. 58, September 1910. Is 
this correct ? I found it growing in the same place and apparently 
under the same conditions as S. squaiidus and S. vulgaris. S. 
squaiidus seems, from the large quantity of it, to have been estab- 
lished in this Northwich station for some years. I submitted fresh 
specimens to Mr. Chas. Bailey, and he was of opinion that it was 
a starved form of squaiidus. — W. Hodge. This is, I think, certainly 
vulgaris, L., var. radiatus, Koch., and apparently a form near to the 
one I name erectus, but probably quite distinct — A. H. Trow.
