150 Transactions. 
Hreractum saxifragum (Fries).—Grey Mare’s Tail, Dumfries- 
shire, collected by J. Backhouse, I think, about 1850 or 1851. 
Mr Backhouse sent this specimen to my friend Mr Hanbury, and 
we took it to Kew on Saturday (27th March, 1886), and com- 
pared it with Fries’ Herbarium Normale specimens, and with the 
specimens from Lindenberg and Scandinavia, and there is no 
doubt Mr Backhouse was right in supposing his specimen was 
H. saxifragum. It is most like some forms of vulgatwm, but the 
leaves have the teeth beyond the general outline, and the hairs 
on the underneath are seated on small tubercules. 
Sparganium neglectum (Beeby).—Three years ago my friend 
Mr Beeby called my attention to some specimens of Sparganium 
he had collected in Surrey, and which he could not make agree 
with either simplex or ramosum. Steadily pursuing his enquiries 
and collecting the plant in all stages of its growth, he felt bound 
to consider that at least it was a new sub-species. He has since 
published it under the above name in the “Journal of Botany.” 
His opinion is concurred in by Dr Lange of Copenhagen, Dr 
Moir of Pisa, Dr Gray of Cambridge U.S.A., and by Mr J. G. 
Baker, Rev. Mr Newbould, &c., in this country. I think it says 
much for the botanical acumen of Mr Beeby, especially occurring 
in a county so well worked as Surrey has been supposed to be. 
Potamogeton pusillus, L., sub-spec., Stwrrochit (A. Bennett).— 
A very beautiful sub-species of pusillus found by Mr A. Sturroch 
in East Perth, which I was unable to match in my extensive 
collection of pusilus from any part of the world, in that at Kew 
or the British Museum, and my correspondents in Sweden and 
the United States (Dr Tiselius and the Rev. T. Morong, both 
specialists in the genus) both concur in considering it separable 
from pusillus ; so I named it after the finder, who has done so 
much good work among the Perthshire aquatics. 
Naias maria, L.—Found by my daughter at the entrance to 
Hickling Broad, in Norfolk, a beautiful sheet of water of about 
500 acres. We were studying the aquatic vegetation, I myself 
looking over the masses pulled up by the ‘‘ drag” she was using, 
and the first sight of it was her asking, ‘‘ What is this?” I saw 
at once it was a Naias new to Britain. We afterwards found it 
scattered for over a mile of water, and last year (1885) my friend 
Mr Mennell found it in Somerton Broad. It occurs in Seandi- 
navia, Holland, Belgium, France, Germany, and other parts of 
Europe. It is an interesting addition, adding as it does another 
link to the flora of Western Europe and East Anglia.
