294 the botanical exchange club of the BRITISH ISLES. 
established for over twenty years at St. Anne’s-on-the-Sea, v.-c. 6o. 
The area represented on the plate has been invaded by drifting 
sand, and building operations have begun in its immediate neigh- 
bourhoo'd. The Club is indebted to the Manchester Literary and 
Philosophical Society for the use of the plate. It was issued with 
a paper entitled “ Further Notes on the Adventitious Vegetation 
of the Sandhills of St. Anne’s-on-the-Sea,” read 9th April 1907, 
a copy of which was posted to each member of our Club. — Charles 
Bailey. 
Achillea, sp. Pettycur, Fife, i8th July 1907. — W. R. Linton. 
We found a good patch of this alien by the railway embankment. 
1 don’t know the species.- — E. S. M. The Achillea (unnamed) 
seems very near to A. lanata, Spreng, if not quite it. But this sec- 
tion of the genus is variable and rather perplexing. — J. W. White. 
Alatricaria suaveoletis, Buchen. (= M. discoidea, DC.). By 
the railway at Basingstoke, Hants. New county record. Sept. 
1907. — G. Claridge Druce. 
Senecio viscosus, L. Railbanks near Walton, Liverpool (v.-c. 
59), Aug. 1907. New to S. Lancs. ? This plant, which is not 
recorded for the north side of the Mersey in Green’s ‘ Liverpool 
Flora,’ did not occur in this locality until this year. The ground 
was disturbed (but no ballast brought) to lay a temporary railway 
siding, and unless seed was brought with the rolling stock or plant, 
it would appear to have been dormant in the soil. — J. A. Wheldon. 
S. viscosus, L. Highley, Salop, Aug. 19th, 1907, v.-c. 40. 
— W. H. Painter. Growing upon railway sidings in great pro- 
fusion. Doubtless introduced with ballast. 
Ctiiciis tuberosus, Roth. Orig., Nash Point, Glam. ; cult., 
Llandaff, 5th and 12th Aug. 1907. Also (A) heads cut from wild 
plants, 7th Aug. 1907 ; and (B) ripe heads from the native locality. 
Sept. 1907. Many members already have sheets of the wild plant : 
the cult, specimens are added in illustration of certain points. 
Fruit ripens freely in the wild state (B), but much more sparely 
in cultivation. The cultivated plant is very luxuriant, often de- 
veloping a large number of branches, heads, and stem leaves. 
Though the wild plant makes good specimens and preserves its 
colour well, yet elaborate precautions have failed to keep a good 
colour in specimens from the garden : at any rate, in 1907. 'Flus 
may be due to the heavy clay soil, or to the unusually cold 
season. 
The plant has fleshy ‘ tuberous ’ roots, and not the creeping 
rhizome found in C prateitsis, Willd , and C. Woodivardii, Wats.
