Rosa micrantha , Briggsii. 15th July, 1883. — J. W. White. “ R. 
micrantha , Sm., var. pedunculo-nudo , of which Briggsii , Baker, is only 
a luxuriant form. I find this variety of micrantha growing sponta- 
neously in some of the hedges very near the house where I write this.” 
T. R. Archer Briggs. “Two years ago I sent to the Club fruiting 
specimens of this rose, which had been determined by Mr. Briggs 
himself. Other botanists, however, considered it to be a form of R. 
sepium , and wished for examples in flower by which to settle the 
question. These are now supplied.” — J. W. White. “ R. sepium , 
var.”— J. G. Baker. 
Rosa sepium. Buckden, Hunts, 5th Sept., 1884 — W. R. Linton. 
“ This Rose, with its very short peduncules, differs slightly from the 
next ( micrantha , v. pedunculo-nudo). It cannot be the typical R. 
sepium of Thuillier’s ‘ FI. des Env. de Paris,’ which work I know, and 
the description of R. sepium has £ fructibus oblongo-ovatis.’” — T. R. 
Archer Briggs. Passed by Mr. J. G. Baker. This, as Mr. Briggs 
rightly remarks, has not the fruit of the original sepium , but it seems 
best placed under it ; it is less different than a curious form that 
occurs in Surrey, which M. Crepin seems inclined to refer to a rare 
Continental species, but which has all the essential general characters 
and growth of sepiu 7 n. Herr von Uechtritz, to whom I sent Surrey 
examples of this form, considered it represented Thuillier’s “ sepium , 
inodora , Fr.” but I cannot agree with him in either reference, but at 
present I know not what name to give these Surrey specimens. 
Rosa canina , L., var . frondosa. Buckden, Hunts, 4th Sept., 1884. 
W. R. Linton. Passed by Mr. J. G. Baker. 
Rosa canina, pruinosa. Glen Shee, Perth, 1st Sept., 1884. — E. F. 
Linton, “ Similar to a plant so named sent out through the Club 
last year. Seems correctly named.” — T. R. Archer Briggs. Passed 
by Mr. J. G. Baker. 
Rosa canina , L., var. arvatica. Ellington, Hunts, 9th Sept., 1884. 
W. R. Linton. “Is tomentella .” — J. G. Baker. 
R. canina , andegavensis. Hereford, 16th July, 1884. — A. Ley. 
“I suppose andegavensis, which has sometimes, at least, serratures of 
the leaflets irregularly cut and petioles hairy, thus not differing from 
lutetiana beyond having aciculate peduncules.” — T. R. Archer Briggs. 
Rosa canina, L., var. andevagensis, Bark. Ellington, Hunts, 9th 
Sept., 1884. — W. R. Linton. Bromsgrove, Worcester, 26th June, 
1884. — E. F. Linton. Saint Weonards, Herefordshire, . 19th July, 
1884. — A. Ley. All passed by Mr. J. G. Baker. 
Callitriche verna, L. Pinner, Middlesex. 2nd June, 1884. — W. 
R. Linton. The deciduous character of the styles, and smallness 
of the fruit are in favour of vernalis , Kutz. The sinus of the fruit, on 
the other hand, is rather deep, and the lobes are slightly winged. It 
therefore, seems intermediate between vernalis, Kutz., and stagnalis. 
Scop. It was growing in some inches depth of water in a ditch. — 
W. R. Linton. “ I see what seems to be a wing to the fruit of this 
specimen.” — C. C. Babington. 
Callitriche pedunculata. Surrey, 28th June, 1884. — W. R. Linton. 
“Not a species, only (as I believe) hamulata on mud.” — C. C. 
Babington. “ Were the fruits here only pedunculed, I should
