SENT from the Scottish coast by our kind friend James
Brodie, Esq. Mr. Stackhouse found it at Sidmoutb, Devonshire,
and his description is the first that ever appeared.
Several fronds, 6 or 8 inches high, arise from a small callous
root. They are light greenish brown, forked, very thin
and membranous, undulated, often tom y furnished with a
strong central midrib, which is slightly prominent, and here and
there proliferous : the extremities are somewhat rounded. The
fructification is scattered over the frond in small roundish
convex dots, the capsules or tubercles crowded, obovate, and
often accompanied by what seems the rudiment of a Conferva,
as described by Mr. Stackhouse, and first ascertained by the
accurate Mr. Woodward. JimA jj.8o7;Hib7uh& b yja f Jcnverly Zemdo/i.
