Carex dioica, Linn., near Bath. 
“This plant was shown me by Mr. Walker, of Bath, a few years 
previous to his death, as being found by him within four miles 
of that city, and recorded on his authority in Babington’s ‘ Flora 
Bathoniensis ;’ not being aware of its having been found since in the 
County by any other botanist, induces me to record this fact, from 
observing in the ‘Cybele’ a doubt expressed as to its occurrence in 
the Peninsular. And I may here remark that Mr. Walker’s au- 
authority could be relied on, having cultivated the rarer British plants 
in his garden, at Bath, for many years.”—Id. 
Herbarium of Rhenish Menthe. 
Dr. Philip Wirtgen, of Coblenz, is about to publish a Herbarium 
of the Menthe of the Rhine, to include all the species, varieties, 
forms and hybrids hitherto collected in the neighbourhood of that 
river. The specimens, correctly named and accompanied by various 
critical notes, will be fastened on white paper, and form a thick folio 
volume. Each set is offered for 16s., and any person desirous 
of becoming a subscriber is requested to signify his intention to Dr. 
Berthold Seemann, Kew, near London. 
Viola lactea and Viola jftavicornis (?\ 
“The following may be added to the list of unrecorded localities 
for the Viola lactea; Mayal’s Green, Gower, Glamorganshire, (from 
which place I enclose a specimen). I have carefully noted this plant, 
and also the V. flavicornis (V. canina var. minor, of Hooker), and 
while I cannot but come to the conclusion that the first (V. lactea) is 
a distinct species, I feel convinced, so far as my. present observation 
extends, that the so-called V. flavicornis is the simplest form of 
a variety of V. canina, namely, a form which is respectively trans- 
mutable by corresponding changes of soil and circumstance: and 
which may be met with in the neighbourhood of the supposed lo- 
calities of the V. flavicornis in every intermediate stage of develop- 
ment.” —Caroline Catherine Lucas ; Mayals, May 20, 1854.
