specimens, which were very fine last year. I have noticed the plant 
in the same way at Charleston, U.S.A., where it is quite naturalized. — 
J. Cosmo Melvill. 
Caltha palustris , L., var. Guerangerii (Boreau). “Castle Mote,” 
by “White Water ’’River, North Warnborough, Odiham, N. Hants, 13th 
April and 2nd May, 1893. — C. E. Palmer. “I should call this a 
small form of typical C. palustris .” — W. H. Beeby. I cannot refrain 
from drawing attention to the excellence of these specimens, both as 
regards the selection and drying, and the quantity sent for each 
specimen. In determining critical plants, it is much more satisfactory 
to see complete examples, and several of them, rather than the single 
scraps so often sent. — J. G. 
C. palustris , L., var. lata (Schott). Near Shirley, S. Derby, May, 
1889, and May and June, 1892. See ‘ B.E.C. Report,’ 1889, p. 244. 
Transplanted into the garden it retains the two characteristics of non- 
contiguous sepals and straight-beaked follicles. — W. R. Linton. 
“Since Dr. Beck’s ‘ Revision,’ Dr. Huth has published (Berlin 1891) 
a ‘ Monograph of the genus Caltha, , in which C. lata, Schott, is 
reduced to a variety of C. palustris, and C. Guerangerii, to a form of 
his v. typica of the same species. Now that I have specimens of C. 
lata, I think that Mr. Linton’s plant must come under C. Guerangerii, 
as he at first thought. — W. H. Beeby. 
C. palustris, L. var. procumbeus, Beck. Rothiemurchus Forest, 
Easterness, 31st May, 1892. Not well illustrating the var. as the 
rootlets at the node have not developed, but would have done so. — 
A. Somerville. “ Mr. Somerville is probably correct in thinking 
that his plant would have rooted at the nodes later on ; assuming this 
to be so, I should refer the plant to var. radicans rather than to var. 
procumbe 7 is, but I only know the latter from Dr. Huth’s description. 
Dr. Huth describes four rooting varieties of C. palustris, but these 
probably pass gradually into each other, judging from my experience 
of rooting forms in Shetland.” — W. H. Beeby. 
Barbarea . Shiplake, and Marcham, Berks., May, July and 
August, 1893. I have sent this plant of our shady stream sides, which 
is referred to B. vulgaris, Br., var. divaricata ; on account of its near 
resemblance to B. arcuata, Reichb. The ripe seeds of our plant are 
shorter and broader than those of Reichenbach’s type plant. Is the 
difference in the shape of the seeds constant? — G. Claridge Druce. 
I should say B. vulgaris ; very like a plant from Thursley labelled 
var. divaricata by Mr. Watson. — J. G. 
B. intermedia, Boreau. Near Witley, Surrey, 10th June, 1893. 
Passed by Svante Murbeck as correct. — E. S. Marshall. 
Arabis petraa, Lam. var. hispida, DC. Near the top of Larig 
Pass, Cairngorms, Easterness, at alt. 2,600 ft. 21st July, 1892. — 
A. Somerville. 
A. petraa, Lam. var. grandifolia, Druce. Alpine cliffs, Ben a 
Chleibh, Argyll, 5th August, 1893. — W. A. Shoolbred. Ben Laoigh, 
Mid Perth, 7th August, 1893. — R. W. Scully. It would appear
