Turn. Hist. 113 — E. Bot. 2116. ' 
Stems half an inch long; leaf half an inch to an inch in diameter. Colour 
a pale blood red, semi-transparent, soon fading on exposure to the sun. 
The remarkable shape of its leaves seem to keep it distinct from all other 
species. It is of very unfrequent occurrence, and seems to be only found 
cast on the shore after storms. 
Kidney-shaped Fucus. At Niton, Isle of Wight, Miss E. Everett; at 
JBudleigh, Mrs. Griffiths; Cornwall, Mrs. Itashleigh. Turn. Hist.

F. Iioloseta^ceus Stem short: leaves membranaceous, without a 
mid-rib, edged with prickle-shaped teeth and producing similar 
prickles on both surfaces. 
[Turn. Hist. 70 — E. Bot. 1069. E.)— Gmel. 21. 2. 
Membranaceous, firm, diaphanous, without a mid-rib, branched, six inches 
over, branches alternate, somewhat winged. Primary leaf one inch broad, 
secondary two lines, edges fringed with distant, upright bristles differing 
in size, simple or forked. Both surfaces have some of these bristles 
which are stiffer and sometimes hooked. Gmelin. Stem three quarters of 
an inch high, whole plant from three to five inches high; blood-red. 
Leaves from a quarter to near half an inch broad, the former not 
branched, but all of them edged with prickle-shaped substances the same 
as those on the surface. These vary much in size, are sometimes com¬ 
pound, but have never the appearance of fructification like the fringe in 
F. laciniatus. 
(Blood-red Prickly Fucus. F. holosetaceus. Gmelin. F. ciliatus. Tur¬ 
ner. E.) 
Var. 2. Leaf simple, one to one and a half inch long. 
Mr. Lightfoot arranged this as a variety of his F. ciliatus, but the existence 
of the prickles and the length of the stem induce me to consider it as a 
young plant of F. holosetaceus. 
On rocks and stones in the sea; chiefly in summer and autumn. On the 
Cornish coast. Mr. Stackhouse. 
F. pro'lifer. Leaves flat, membranaceous, without a mid-rib; chain¬ 
like-proliferous, cloven at the end. 
Lightf. 30. at p. 949— FI. Dan. 708. 
Membranaceous, red, without a mid-rib, four or five inches long, a single 
leaf about a quarter of an inch broad. Proliferous from tbg surface, not 
from the edge ; shoots forked. Fructifications red spherical warts scat¬ 
tered on the surface of the leaves, smaller than pins’ heads. Lightf. 
A singular variety of this is represented in Mr. Stackhouse’s second 
Fasciculus of British Marine Plants. It is proliferous only at the edges 
and at the lacerations, and in habit is perfectly distinct from the plant 
of Lightfoot, approaching to F. pahnatus, but possibly a new species.

other Corallines, which give it a scabby appearance. E.)
