the lower sopen, openly wooded with angna still very numerous, but 
once covering the who le district. In one of the south shore of the 
miles, and, from its sombre appearance, is aptly named the “ Black Wood.” 
The timber of this forest is celebrated for its durability, and, only a few years 
ago, was valued at about £22,000. In its recesses occur many insects not 
found in any other part of Britain, and some even, as yet, un undetected in any 
other place w whatever. He concluded by giving a list of the plants he had col- 
lected in the district, and noted their altitudes, which were generally greater 
than anywhere else in Britain. III. Notice of a new Carduus gathered 
during a Botanical Visit to Ross-shire. By Mr. Charles Howie and Mr. 
Charles Jenner. Mr. Jenner laid on the table twelve sheets of specimens of a 
Carduus, new to Britain certainly, and icta new to Europe, if not new to 
science. The descriptive aui of the plant, which it is proposed to 
Carduus Carolorum, will show botanists its p peculiarities. It does 
not vary much from a ve preme by Linneus in his ‘ Species Plan 
Am 1753, under the name of Carduus Doles found in Siberia; but it 
s distinguished from it by some marked specific differences. It was gathered 
n the borders of igs Oo within a very circumscribed area, growing on a 
high bank above a rocky streamlet. Grim old indigenous trees of the Pinus 
sylvestris were thinly scattered up and down , and mountains of considerable 
elevation shadowed the place. This Carduus may perhaps be a hybrid between 
be in every respect a true species, maintaining its iil in nature by the power 
it has of reproducing itself, and of conserving its ow special characteristics. 
The following are the characters :—Root perennial, Rekst deeply rooting in 
the soil, cæspitose, producing several stems. reay from 2 to 4 feet high, fur- 
rowed, slightly cottony, leafy from top to bottom, m, terminating in a corymb of 
m five to nine capitula. Leaves—Root- -i lanceolate, gradually tapering 
hi 
upper surface pilose. Stem-leaves from twenty to thirty (cottony beneath also, 
and pilose above), lower narrowing into long winged petioles, lobed as well as 
deeply toothed, upper leaves more nearly sessile, semi-am amplexicaul, with de- 
mit s 
current auricled prolongations; nea the s aller, sharply toothed, 
pute. at the point; Aom yore arkeneped. Involucres obovate or globular. 
adp inate, dentate towards the apex. Pa

Flowers purple. A very handsome plant. IV. On the Botany ofi Frodsham 
Marshes, Cheshire. By Mr. J. F. Robinson, communicated by Mr. Sadler. 
Frodsham Marsh is a large tract of low-lying land, b bounded on the north-east 
by the river T and on the north-west by the river Mersey ; it is mostly 
well drained by gutters, which empty themselves into large ditches, the water 
eventually wd conveyed to the river. As might be expected, the plants are 
principally aquatie species. The most conspicuous are Butomus umbellatus
