It is usually about three inches high. Its small solid root sends forth 
many cylindrical pale yellow stems, pinnated from their very origin, 
with short, opposite distichous, horizontal shoots, in general simple, 
sometimes extending into new branches ; joints cylindrical ; septa darker, 
and thence conspicuous. Whole plant pellucid, except the capsules, 
which are opake, and visible only with a good glass. 
(Yellowish Pinnated Conferva. Named after Professor Mertens of 
Bremen, by whose labours this genus is likely to be more fully illus¬ 
trated. This new species was first found on the beach at Yarmouth by 
Mr. Wigg; but always in very small quantity. The peculiarity of its 
habit brings it near to Fucus Wigghii, and makes it one of the many links 
that unite the two genera. E. Bot. E.) 
(C. biddulphia'na. Pale green; filaments capillary, simple, some¬ 
what compressed; joints quadrangular, longitudinally striated; 
at length separating at one of their edges and divaricated. 
E. Bot. 17 62. 
Filaments about half an inch long, nearly three times as thick as those of 
C.Jloccidosa, and less compressed. 
Disjointed Marine Conferva. Found by Miss Susannah Biddulph at 
Southampton, entangled with various marine productions. 
Nov.—Dec. E. Bot. E.) 
(C. eor'reri. Bright red; capillary, repeatedly branched; branches 
all alternate, spreading in two directions, zigzag; the ultimate 
ones level-topped: joints cylindrical, twice as long as broad- 
E. Bot. 1741. 
Grows from a small disk, in tufts about two inches high, of a beautiful pink

Bosrerian Conferva. This elegant species was gathered on Yarmouth 
beach in October, by W. Borrer, jun. Esq. F. L. S. E.) 
(C. elocculo'sa. Green, filaments capillary, mostly simple, com¬ 
pressed : joints quadrangular, transversely striated; at length 
separating at their alternate edges and divaricated. 
Dillw. 28— E. Bot. 1671. 
This wonderful and minute plant forms light green or brownish tufts about
