Cnicus palustris Willcl, var ferox Druce. The Mineries, Priddy, 
N. Somerset, v.c. 6, July 4th, 1919.— Ida M. Roper. Yes, 
Cirsium palustre , var. ferox Druce. — G.C.D. Agrees with Dr. 
Druce’s description of his ferox, which I presume differs from var. 
spinosissimum Willk. ? — C.E.S. 
Centaurea nigra L., [var. radiata ( teste Dr. Rendle).] Hedgerows, 
S. Tawton, N. Devon, v.c. 3, August, 1919.— PI. E. Fox. A 
handsome plant with conspicuous rayed outer florets. Most 
botanists who have studied Centaurea must have experienced the 
inadequacy of referring similar plants to C. nigra, “var. radiata.’’ 
Although coming under the aggregate C. nigra L., this plant, by 
reason of its ovoid heads and lanceolate disks of the bract-scales, 
must be placed to the segregate C. nemoralis Jorcl, which appears 
to be the usual British representative of C. nigra. Gugler, who 
ranks nemoralis as a subspecies, divides it into two varieties, 
(1) Jordani, characterised by its ray-less heads and black scales, 
and (2) Nevadensis, distinguished by its brown somewhat smaller 
-scales and rayed outer florets. The Rev. H. E. Fox’s plant 
clearly comes under the latter variety, although it must be 
admitted that, in some of the specimens, the colour of the scales 
approximates to black rather than to brown. This form seems 
frequent in some of the southern counties of England. — C.E.B. 
This I consider comes under C. nemoralis Jord., which is 
occasionally, though not normally, rayed. — C.E.S. 
C. Calcitrapa L. Turf Common, nr. Carter’s Bridge, Dodding- 
ton, Cambs., v.c. 29, July 9. 1919 (with Marrubium vulgare L.). 
Mr. J. L. Luddington found the plant here in 1918. A gypsy 
From a camp on the turf common directed me to it, saying that 
le had known it there some eight years, and that he did not 
enow another plant of it between Doddington and the Hundred 
)f Hoo (Kent). The gypsies value a decoction of the plant as a 
;ure for stone. — J. E. Little.
