growing in mud, lias been to find it with spatlmlate-obovate leaves. 
— J, T. Boswell. 
Callitnche obtiisatu/iila, Le Gall. — Water-trenches on the Lache 
Eyes, S.W. of Chester City.— F. M. Webb & J. L. Warren. Mr. 
Webb first observed this plant near Chester. We saw the species 
in at least five other stations in the county. On the Lache Eyes 
(brackish water), it grows in great profusion in company with 
Ranunculus Baudotii, cirdnatns, Drouetti, and a number of common 
sub-maritime species. It will probably prove to be widely diffused 
in Cheshire. — J. L, Warren. This seems to mo C. ohttisanfiula 
without doubt. The styles are considerably shorter, and the fruit 
narrower, and the lobes more obtuse than in the plant Mr. Warren 
sent under the M.S. name, C. Lachii, Tabley Moat, Cheshire, Sep- 
tember, 1868, ‘ Bot. Ex. Eeport,’ 1875, p. 17. — J. T. Boswell. 
C. ohtusawjula, Le Gall ? Plant on Barnes Common, near the 
northernmost of the two cemeteries. Surrey, August, 1871. This 
specimen did duty for three years as “ vcrna ” in my collection, but 
I suppose now it must go as above. Mr. Pryor has, I believe, 
found this species inland in Herts. I have no means of turning 
to the reference in ‘ J. of B.,’ before my parcel goes. — J, L. Warren. 
Mr. Warren, who has seen the plant alive, must be best qualified 
to decide its nomenclature. I should have called it C. jdati/carpa, 
because the margins of the carpels are distinctly keeled, but this 
may readily have arisen from their shrinking when drying if they 
were not quite mature. — J. T. Boswell. 
“ C. verna.” Chesterton Pool, Warwickshire, July, 1876, — 
E. L. Baker. This seems to me the same plant as that which the 
Honourable J. L. Warren names Lachii in ‘ Bot. Ex. Club Eeport ’ 
for 1875, p, 17, but which I believe, he now refers to C. ohtusanriula. 
It has the general habit of G. ohtusangula, but the large fruit is 
less obtuse on the margins, and the styles are very long and ulti- 
mately reflexed, — J. T. Bos'well. 
“ C. ohtusamjula.” Bracldsh marsh, Belfast Harbour, August, 
1876. — S, A. Stewart. These specimens have no fruit sufficiently 
matured to enable me to arrive at an opinion. The habit of the 
plant is that of C. stagnaiis instead of G. ohtusangula, but I never 
met with that plant in brackish water. G. ohtusangula, Le Gall, 
near Eomsey, South Hants, July, 1876, J, Groves, is right. — 
J. T. Boswell. 
Rihes ruhrum, Linn. By the stream between West Sherford 
Farm and the Plymouth and Yealmpton Eoad, S. Devon. April 
25, 1876. I have found it impossible to divide the specimens of 
the “Eed Currant” collected in the neighbourhood of Plymouth 
between the varieties sativum and sylvcstre of ‘E.B.,’iii. — T. E. A. B. 
This is the var. ft. sylvcstre. — J. T, Boswell. 
Sa.vifraga cernua, Linn. Ben Lawers, Perth, 1876. In former 
visits to Ben Lawers I have found this, sparingly, in the 
“ Ordmance Gully,” near the summit: this year, July 15, I only 
saw one plant there, but among rocks facing the west, a little 
higher, it was growing in fair quantity, with many plants coming into 
flower. I got one in full bloom, but none in fruit. — G. Horn!
