rootstock with elongated stolons, and so is the variety ‘ radice 
maxime repente,’ mentioned but not named in the Species 
Plantamm, ed. 1. It would be more correctly classed as S. 
fluviatilis Wallr. = S. salicetorum Godr. Linneus’ S. sarracenicus = 
S. Fuchsii Gmelin is another plant . . . and of quite other 
habitats, frequenting moist places in woods and wood-borders 
[often among boulders] in Alpine districts up to say 5—6000 ft.” 
Colonies of the young and very erect shoots seen in the meadow 
grass at the end of April, 1925, when fishing in the Chew, look 
strange, and would be puzzling unless one had seen the plant in 
autumn. — H.S.T. 
Cnicus pmtensis Willch, var. polycephalus Druce. Meadow, Ash- 
cott Moor, N. Somerset, v.c. 6, June 19, 1924. — Ida M. Roper. 
A not infrequent form ; but Cirsium britannicum Scop, is a better 
name for the type. Will members look for the scarce hybrid 
with palustre, which is wanted on the Continent (particularly by 
Dr. Petrak) as well as at home ? — H.S.T. 
G. arvensis Hoffm., var. vestitus Koch. Waste ground, Cam- 
bridge, July 29, 1924. — A. J. Crosfield. Koch’s name for this is 
Cirsium arvense 8 vestitum in his Synopsis, Ed. 2, Vol. 2, 457 (1844). 
In that work he gives a very full and possibly overlooked 
account, by C. von Naegeli, of Cirsium with its varieties and 
hybrids. — H.S.T. 
Cev.taurea obscura Jord., f. racliata C. E. Britton. Tors, Ilfra- 
combe, N. Devon, v.c. 4, July 14, 1924. — D. G. Catchesicle. 
Although the appendages are very dark, I am afraid that these 
specimens must be placed to C. nemomlis rather than to C. obscura. 
In shape and size the capituli are just those of the first-named. 
C. obscura should have sturdier-looking heads. The foliage is, on 
the whole, fairly uniform, and brings the plants to what I have 
called C. nemoralis Jord., var. subintegra f. radiata. — C. E. Britton. 
C. nemoralis Jord. forma det. C. E. Britton. Clandon, Surrey, 
v.c. 17, Aug. 2, 1923. — W. 14. Sherrin. Comm. J. L. O’Loughlin. 
C. aspera Linn. Le Quenvais, Jersejq May 31, 1896. — J. W. 
White. A few of the more vigorous specimens of this gathering, 
with the leaf bases distinctly auriculate, may be safely placed to 
var. auricularia DC. in Prodr. 6, p. 600, described in the follow- 
ing terms: “foliis inciso-dentatis basi utrinque auriculatis am- 
plexicaulibus.” I have indicated the specimens that, in my 
opinion, may pass as the variety. — C. E. Britton.
