Potamogeton varians , Morong ! P. spathceformis , Tuckerman !

13th August, 1892. — A. Fryer. 
P. falcatus, Fryer. Stocking Fen, Ramsey, Hunts., 16th July, 
1887. — A. Fryer. “Mr. Fryer seems to have very fully explained 
the position of this plant in the ‘Journal of Botany.’ I have seen 
specimens that come very near it from Switzerland.” — A. Bennett. 
Zoster a marina , L. var. angusiifolia. Loch Carron, Ross, August, 
1893. — H. E. Fox. 
Eriophorum gracile, Koch. Near Little Sea, Dorset, 16th June,

Sent by W. R. Linton and E. S. Marshall. From the same locality 
(fruit), 30th May, 1893. — R. P. Murray. 
Carex disticha, Huds., form with long bracts. Near Coron Lake, 
Anglesey, June, 1893. — J. E. Griffith. “I think correct, as it 
really seems disticha by the intermediate flowers, &c.” — A. Bennett. 
C. paniculata , L., sterile form. Near Shirley, S. Derby, July, 
1887. A great deal of this occurs in this district along with C. 
disticha ; at first I thought it a hybrid, but now regard it as a sterile 
form. — W. R. Linton. “I am not sure I understand what Mr. 
Linton means, as I find plenty of good fruit with perfect nuts j 
certainly a proportion are sterile, but it is far from absolutely 
sterile.” — A. Bennett. 
C. muricata , L., var. virens , Koch? Oystermouth Castle, Swansea, 
Glamorgan, 31st May, 1888. See B. E. C ‘Report,’ 1889, p. 272, 
and 1890, p. 313. The above name was suggested by Rev. 
E. S. Marshall. — W m. R. Linton. “ May be, but I should have 
hesitated without perfect fruit to separate it from divulsa .” — A. 
Bennett. 
C. acuta , L., var. gracilescens, Almq. Meadow near the Avon, 
near Christchurch, S. Hants, nth May, 1893. Found only at one 
spot, in an irrigation ditch, whereas the type was rather frequent, in 
similar situations and on the river bank.— E. F. Linton. “ Closely 
agrees with specimens so named by Almquist.” — A. Bennett. 
C. Goodcnowii , J. Gay, alpine form. Correifron, Moffat, Dumfries. 
Glen Fiagh, Clova, Forfar, July, 1890. — W. R. Linton. “The 
fruit is not ripe enough. I should have hesitated as to a form of 
rigidaP — A Bennett. 
C. binervis , Sm., alpine form. C. Ceanmor, S. Aberdeen, Aug., 
1887. Seems much the same as the specimens named nigrescens in 
last year’s ‘ Report,’ p. 388 . — Wm. R. Linton. “The fruit is longer- 
beaked and the lower flower glumes have the midrib exserted instead 
of, as generally, only mucronate.” — A. Bennett. 
C. fulva , Good., var. Hornschuchiana, Hoppe. Dunmore, West- 
meath, 17th June, 1892. — H. C. Levinge. 
C. Jiava , var, lepidocarpa , Tausch. ? Botcheston Bog, Leicester- 
shire, June, 1893. I send a few specimens of our Leicestershire form 
from another locality, several miles south of Charnwood Forest, in a 
boggy meadow with Menyanthes , &c. The stems of these are 
distinctly scabrous on one side under a power of 60 diameters, toothed
