 HAB. Common on rocks,, stones, &c., in the sea. /3. Coast of Mo- 



ray, Mr. Brodle, Mr. Borrer and Hook. 

 From 4 6 inches long, of a blackish brown colour, bushy. In C. ni- 



grescens, the branches are fewer and straighter; I suspect, the 



eifect of injury. j3. is small, reddish and fibrillose at the extremity, 



probably only the young state of the plant. 



4. H. urceolatd) filaments very much branched bushy, branchlets 

 short and spreading, lower articulations much longer, upper 

 shorter than broad, capsules urceolate. Conferva urceolata, 

 Lighlf. Mss. (according to Mr. Turner}. Dillw. Syn. p. 82.

HAB. Rocks and Fuel, at Forres, James Brodie, of Brodie, Esq. 



Firth of Forth, near Kirkcaldy, Mr. Greville. 

 From 4 to 6 8 inches long, very bushy, of a fine deep pellucid red 



when fresh, blackish brown when dry. 



5. H. ladia, "filaments branched straight reddish black, branches 

 elongated, branchlets abbreviated remote subsimple, articula- 

 tions half as long again as their diameter/' Dillw. Ag.p.^bl 

 Conferva badia, Dillw. Conf. Syn. p. 85. /. G. 



HAB. Shores of the Firth of Forth, near Kirkcaldy, Mr. Greville. 



Mr. Dillwyn says " this is intermediate between \hzfucoides and wrceo- 

 lata, from both of which it may be distinguished by its articulations, 

 which are nearly of the same length throughout." If that be the case, 

 it cannot be the H. badia of Agardh (who indeed quotes Dillwyn, 

 the original authority for the name, doubtfully) j for he expressly 

 says, that the lower articulations are twice as short as they are broad, 

 and that the upper ones are thrice as long; and he compares his 

 plant with H. stricta, from which he tells us it differs in colour. 



6. H. stricta, filaments branched nearly equal slender fastigiate 

 purplish red, branches dichotomous nearly erect, articulations 

 about thrice as long as they are broad. Ag.p. 56. Conferva 

 stricta, Dillw. Conf. Syn. p. S3. 



HAB. Rocks, &c., in the Firth of Forth, near Kirkcaldy, Mr. Grcville. 

 About 4 5 inches long, remarkable for its slender straight twiggy 

 branches, long joints, and fine colour. 



7. H. Brodicei, filaments very much branched purplish black, 

 branches elongate, branchlets scattered patent fasciculated 

 limltind, articulations of the main branches obsolete, th^e of 

 the branchlets about half as long again as broad. Conferva 

 Brodicei, Dillw. Conf. t. J07. E. B. f.2589.
