102 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
Thalictrum fiavum , L., var. spharocarpum. Blackwater, Surrey, 
30th August, 1884. The achenes are, as usual, attacked by some 
gall insect. The perfect fruits, which can only be detected by cutting 
sections, seem to belong to this variety. — W. H. Beeby. 
Thalictrum flavum , L., var. Morisonii. Clifton Ings, near York, 
July, 1884. — G. Webster. “ Simply a galled state.” — J. G. Baker. 
Ranunculus Lingua, L. Northumberland. Becoming rare, and 
likely to be extinct. — H. E. Fox. The notes on the probable cause 
of the extinction of any species are always valuable, and I would 
suggest to the members that any facts that they could put on record 
respecting this subject would hereafter be of great value. In the 
Journal of the Linnean Society — “Botany,” No.‘ 136, 1885 — Mr. F. 
C. S. Roper calls attention to the “ early submerged leaves ” of this 
species, and mentions that they are rarely alluded to by authors. Some 
further details will be found in M. Crepin’s ‘ Notes sur quelques 
plantes rares ou critiques de la Belgique,’ Fas. 5, p. 17, 1865. We 
know so little of the life history of aquatic and semi-aquatic plants 
that it is always desirable to call attention to any notes on them. 
Ranunculus auricomus , L. var. incisifolius,. Reich. Ic. Lane near 
Ockley, Surrey, on the weald clay, 14th April, 1884. I have not seen 
this form, which agrees well with Reichenbach’s plate both in the 
larger flowers and greatly cut bracts, except in the above station. 
On the chalk the bracts are sometimes somewhat bluntly lobed, but 
not cut as in the present plant. — W. H. Beeby. 
Caltha minor. August 13th, 1884. What I am now sending 
from Glen Callater, Aberdeen, approaches radicans more closely even 
than what I sent last year, having triangular toothing of the leaves 
besides rooting at the nodes ; the shape of the leaf is not exactly 
“deltoid.” — E. F. Linton. “I think that these specimens of Caltha 
are palustris , minor P — C. C. Babington. 
Fumaria confusa. Cambridgeshire. — A. Fryer. 26th June, 1884. 
“ Of the Fumarice. capreolatce. segregates, I understand and can clearly 
distinguish only F pallidiflora , Jord., and F confusa , Jord. Of course 
Mr. Fryer’s plant is not the former. F Borcei I do not understand, 
nor F muralis , Sonder.” — T. R. Archer Briggs. I called this confusa 
for Mr. Fryer and I still think it so. 
Fumaria confusa,] ord. Fields near the village, Holy Island, Cheviot- 
land. New to county. See Baker’s Flora, and Topi. Botany. — H. E. Fox. 
Fumaria densiflora , DC. With confusa in Holy Island; only 
recorded station in two northern counties. — H. E. Fox. 
Cochlearia anglica , L. To illustrate the divergence believed to 
exist between the Bristol plant and the type. — J. W. White. 
Thlaspi perfoliatum , L. Stony ground near Charlbury, Oxon., 
April, 1884. Sent in order to show that it still exists in Oxfordshire, 
for which county it is queried in Topi. Botany. It occured in many 
thousands in the above locality, which is about 8 miles from the 
Binford locality mentioned in Sibthorp and other authors. — G. C. 
Druce. This is a very interesting re-discovery of a very local plant. 
Viola Curtisiil Sandhills, Ross Links, Cheviotland. Only two or 
three large plants, not hitherto recorded from E. Coast. — H. E. Fox. 
“Yes.”— J. G. Baker.
