F. Nearly stemless: leaves flat, membranaceous, without 
a mid-rib; branched: branched widening, hand- 
shapéd, ; 
Membranaceous, firm, pellucid, of a fine red colour. Leaf 
without a mid-rib, branched, branches mostly forked. Three 
to 4 inches long, 4 or 5 broad, but a single division about 1 
inch broad. Sides and ends of the branches fringed and tooth- 
ed. Secondary leaves only about a line in breadth. Gein. i

lacinia’tus. 
Neither this nor the next var. can properly be said to have any 
stem, there being only a small knob serving the purpose of a 
root. Both of them are occasionally proliferous, sending out 
rows of young leaves from the edges of the old ones; though 
possibly, only when some injury has been sustained. Gmelin 
says his plant was of a dirty yellow colour, whence I conclude 
his specimens had been exposed to the weather. 
Var. 2. Edges entire.

__F. Jaciniatus. Huds. F. ciliates. Gmelin. Both these va- 
rieties grow upon rocks and stones on our sea coasts, and are 
very conspicuous in the summer months, on account of their 
beautiful red colour, which sometimes approaches to scarlet.

Root branched, flatted, creeping. Leaf 1 to 14 inch long, 
membranacedus, once and sometimes twice cloven, wedge- 
shaped or widening towards the end, purple, semi-transparent. 
Hops. ~. 28. I have never seen. this plant, but whatever the 
specimens may prove, there is nothing in the specific character 
or description of Mr. Hudson to mark it as distinct from the 
F, laciniatus, of which it is perhaps only a small variety. Fucus 
bifidus of Gmelin is a different plant. seicgut see
