2q6 the botanical exchange club of the BRITISH ISLES. 
matches very well with that plant except that the Welsh specimens 
have rather less divided leaves.— A. B. Jackson. On seeing fuller 
specimens of this interesting plant, I witl;draw the suggestion that 
it is the same as a Roundstone, Connemara, plant, and accept 
the present naming. — E.. F. L. I suppose that this is correct. 
But the Avebury plant, which I saw. in good flower in Rev. T. A. 
Preston’s garden at Marlborough in 1885, branched far more freely 
in cultivation. — E. S. M. * 
C. acaulis, Willd., var. caulescens^ Pers. Plentiful in pastures 
on the Lias, about Compton Dundon, v.-c. 6, N. Somerset, 14th 
August, 1907. Ref. No. 3195. — E. S. Marshall. 
C. arvcnsis, Hoffm. var. setosns (Bess). Waste ground. Canton, 
Cardiff, Sept. 1907. I have doubts that this variety is rightly 
named. The plants vary considerably in leaf outline, from entire 
to lobed — the lobes always small. Perhaps it is var. vestitus 
(Vest). Forms of var. miiis were also present. — IJ. J. Riodelsdell. 
According to G. Beck’s arrangement of the forms of Cirsiinn 
arvense in Koch, ed. iii., p. 1553, this is d. arvejise, Scop., var. 
obtusilobum^ forma subincanum, G. Beck. The leaves are not (juite 
so rounded and obtuse, or so distinctly lobed, as in the Bath plant, 
which has also been called setosus, but in error, for C. setosum^ Mey., 
as described in Koch’s ‘ Flora,’ comes under var. commune — the 
section with sharply pointed leaf-lobes. — C. Bucknall and Jas. W. 
White. Agrees very well with foreign specimens so named at 
Kew. For an account of this variety see F. N. Williams’ ‘ Prod. 
FI. Brit.,’ part 2, 51. — A. B. Jackson. This is rather the var. 
miiis, Koch, than var. setosus (Bess.), which has entire or subentire 
leaves. — E. F. L.

Onopordon Acanthium, Linn. A few plants on the sandhills 
off the North Drive, St. Anne’s-on-the-Sea, north-west Lancashire, 
v.-c. 60, 24th August and 12th October 1907. — Charles Bailey. 
Approaching var. viride, Michet ; a form which I have seen at 
Deal, March, and Chatteris. — H. J. Riddelsdell. 
Scrratula tinctoria, L., var. monticola (Boreau). Watermcadows 
in the Parish of Kempsford, Fairford, E. Gloucester, v.-c. 33, 
20th July 1907. Some of the larger specimens have longer 
peduncles, and the heads in that case are larger. Is this the same 
as var. alpina, Gren. and Godr. ? — H. J. Riddelsdell. Similar to 
specimens so named at Kew, but appears to be a mere state, and 
not a good variety. I found a form which appeared to be inter- 
mediate between type and variety on the Downs near Winchester 
in the autumn of 1906, and possibly this was the plant recorded 
from there as var. monticola by the late Mr. F. I. Warner. —
