Carduus anwnsis, Curt., b. ^^setosus.” Eoadside embankment, 
Dean Brae, Edinburgh, August, 1876. Though I had no hesitation 
ill calling what I send setosus as I gathered it, yet when I came to 
label the specimens I felt a trifle doubtful about applying the name, 
the marked diti'erences in life having dulled during the drying 
operation. I find, however, that it accords Avith continental speci- 
mens so named from a good somce. Of course there are all signs 
of a recent introduction surrounding its place of growth, and the 
prominent near companion was luxuriant Chenopodiuw Bonus- 
Henriciia. — F. M. Webb. Field at Newington, Edinburgh, August 
12, 1876. — D. Douglas. 
‘ C. setosus.' No. It is a plant Avhich I have seen several times, 
and which appears in the ‘ Man.,’ ed. i., as /3. latifolius ; but I have 
long since considered it unworthy of distinction even as a variety. 
— C. C. Babington. 
“ Carduus ( nutanti-arv exists ^ )" Eoadside between Gutsford and 
Modbiuy, S. Devon, September 27, 1876. Sent to Dr. Boswell 
with the followhig remarks : ‘ Of very peculiar appearance when 
fresh. Notice the shortly-winged stem ; the peculiar florets and 
anthodes, the latter diuophig from their weight ; and the biennial- 
lookuig root. I saw only the single siiecimen.’ — T. E. A. B. A 
very puzzling plant, evidently a hybrid, of which one of the parents 
is Carduus arvensis, the other some thistle with a winged stem and 
larger heads, quite possibly C. nutans, as Mr. Briggs suggests. 
The gatherer of a hybrid thistle has much the best chance of 
aniving at its parentage by observhig what other thistles groAv in 
its vicinity, which may furnish negative if not positive evidence. 
If it be C. nutanti-arvensis, it is remarkable that the pappus should 
retain the very long secondary hairs, which are as long as though 
fewer in number than in C. arvensis. — J. T. Boswell. 
Arctium nemoroswn, Leg. On quarry spoil-bank at Magheramorne, 
near Larne, Co. Antrim. August 24, 1876. One large plant only 
seen in flower, but abundance of root-leaves all round about. I 
am not aware of any other Lish Biuxlock having been with 
certainty referred to this species. Some years since, while strolling 
over a little island in Strangford Lough, Co. Down, I gathered a 
plant which I sent to Cambridge as probably A. nemurosum. Prof. 
Babington, after diagnosis, wrote me that it looked like the right 
plant, but too immature to be identified Avith certainty. I have 
never ' since been on the island referred to at the proper time to 
search for better specimens. — S. A. Steavart. Prof. Babington has 
certified to the Magheramorne specimens sent out through the Club 
bemg A. nemorosum . — T. E. A. B. 
Cmtaurea aspera, Linn. Vazon Bay, Guernsey; also on the 
hills above St. Ouen’s Bay, Jersey, Avith Centaurea paniculata and 
Scabiosa maritima, August, 1876. — T. B. Bloav. 
C. paniculata. St. Ouen’s, Jersey. July, 1876. — J. Fraser. 
It is interesting to find that this plant maintains its station in 
Jersey, but it is not likely to be native, as it does not occur in the 
north or Avest of France. It is not probable that Professor 
Babington Avould have missed seeing so conspicuous a plant
