Caliha palustris , Guerangerii , Bor. Bradley, S. Derbyshire, May, 
1889. “The two characters relied upon to separate this variety from 
the type are not uniformly found together ; narrow sepals being 
associated with, a short beak, and vice versa.” ‘ Flora of Herefordshire’ 
p. 9. The above remark is borne out by plants of Bradley and 
this district. — Wm. R. Linton. “ I do not think that it is Guerangerii , 
accepting the fruit as belonging to the same plant as the flowers. 
According to Dr. Gunther Beck’s Revision (1886) of Caltha it would 
seem that the description of Guerangerii as having long-beaked fruit 
is scarcely accurate. I understand the real difference to be that in 
Guerangerii the ripe follicle tapers gradually into the beak, while in 
vulgaris , Schott ( = restricted/^j-/m)the follicle is abruptly contracted 
into the beak, the follicle being greatly inflated and gibbous at the apex 
on the inner side. I have no ripe follicles of Guerangerii but my 
half-ripe ones seem to favour the description of tapering gradually, 
which is very different from our ordinary palustris. Mr. Linton’s 
fruit differs from both of the above in the remarkably straight dorsal 
edge of the follicle and according to this would come under the Caltha 
loeta, Schott, N. & K., of Beck’s Revision. This plant and C. cornuta , 
Schott, N. and K., (= Guerangerii) are the only ones Beck keeps up 
as species, out of a lot described by Schott, N. and K. My attention 
has chiefly been given to C. palustris and its forms, and I have no 
specimen of Caltha loeta, but that is the plant to which I think Mr. 
Linton’s example most likely belongs.” — W. H. Beeby. 
C. radicans, Forst. (forma) Yell, Shetland, 28th July, 1889. I send 
a few cultivated examples of this, the plant originally described by me 
as C. palustris var. zetlandica. As already recorded in the “ Scottish 
Naturalist,” subsequent observations have convinced me that the 
rooting stem is the only character not common to both plants ; and 
as this character is very persistent in radicans , while the small 
prostrate forms of palustris (var. minor Mill, non Syme) cannot be 
induced to root, I should now place the Shetland plant under the 
former. — W. H. Beeby. 
Barb area intermedia , Boreau. Yeldersley, S. Derbyshire, June, 
1889. Noticed in two fields about a mile apart. Sent as voucher for 
record. — Wm. R. Linton. A weak unsatisfactory state. Although 
the pods are erect I should not refer it to B. intermedia , the lateral 
lobes of the root leaves being very little developed and the stem 
leaves not being pinnatifid as in that species. — J. G. 
Arabis sagittata , DC. var, glabrata , Syme. Sandhills near 
Darrynane, Kerry, 10th July, 1889. The usual sandhill form of this 
species in Kerry. Typical A. sagittata does not apparently occur on 
these sandhills. — R. W. Scully. 
Cardamine flexuosa , With., var. umbrosa , Gren. et Godr. 
Burghfield, Berks, August, 1889. See Report, 1888, p. 200. 
Luxuriant specimens when over flower remind one of C. amara , 
L. — G. Claridge Druce. 
Diplotaxis muralis , DC., var. Babingtonii, Syme. Near G. W. 
Railway, Warwick, September, 1889. — H. Bromwich. The stem 
is not sufficiently leafy for var. Babingtonii . — J. G.
