in a weedy strip of ground between the corn and the hedgebank. On the 
latter the plant extended for two or three yards only, growing princi- 
pally in one or two large patches. — T. R. A. B. It is the ordinary 
form.— J. T. Boswell. 
Carduus tenuifiorus, Curt., var. pycnocephalus , Jacq. “ In waste 
rocky spots on limestone under the Hoe, Plymouth, S. Devon ; where 
ordinary tenuifiorus also occurs, July, 1875.” M. Deseglise, to whom 
I sent a specimen, regards this as the true pycnocephalus , for which it 
was recorded by Mr. Keys. It looks considerably different from our 
ordinary tenuifiorus. — T. R. A. B. This looks much like true 
pycnocephalus , but has the spines of the leaves much stronger than in 
any of my Continental specimens of that plant. I should like much 
to see the lower leaves of the Plymouth “pycnocephalus.” — J. T. 
Boswell. 
Arctium intermedium , Lange. “ Grown from seed collected whilst 
in company with Prof. Lange, near Copenhagen, July, 1872.” — F. J. 
Hanbuby. Prof. Babington, on receiving a specimen of the cul- 
tivated plant, wrote : “ The Copenhagen plant is certainly inter- 
medium .” The stem-leaves in these specimens are very broad, and 
remarkably cordate or lobed at the base ; blunt, or ending suddenly 
in an extremely short point. Root-leaves are unfortunately wanting.

Arctium nemorosum , Lej. “ Field hedge, Welwyn, Herts, August, 
1875. This occurs in several places around Welwyn, by field sides or 
in bushy places. It is a large (5 feet high) handsome plant, and is very 
strikingly different in habit to any other Arctium. The heads are 
large, almost or quite sessile, and much contracted at the mouth in 
fruit. 1 noticed it in E. Kent last autumn.” — T. B. Blow. Prof. 
Babigton has favoured me with the following remarks on this plant ; 
“ I think that Mr. Blow’s plant may be correctly named, but should 
like to have seen a root-leaf. These pieces may have been branches, 
and therefore of no value for inflorescence. Nevertheless, they are so 
like my specimens that I consider the name correct.” — T. R. A. B. 
Senecio vulgaris, Linn., var. ; probably hibernica, Boswell, in 
Report B. E. C., 1872-74, p. 27. “ Tregantle, E. Cornwall, April 17, 
1875.” A striking variety, of dwarf habit, having heads with a ray 
of conspicuous patent ligulate florets, at least one-third the length of 
the anthodes (in the fresh plant). A few dozen of small plants were 
growing in sand that had been blown from the shore up over a low 
cliff. Noticed again in the spring of 1876. — T. R. A. B. This 
seems precisely the plant mentioned in the Bot. Ex. Club Report cited 
above. The second generation from the Cork plant retains the ray, 
which is at first flat and then becomes revolute. Every seed seems
