S o much does this plant resemble the Bryopsis plumosa,
already given at t. 2375 of this work, that Dr. Greville,
whose authority is of great weight in this family, scarcely
believes it to be specifically distinct, depending for its character
upon the nearly erect and irregular ramuli. The
specimen here figured was communicated by Mr. Borrer
from Tor Abbey, Devon, where it was found by Mrs. Griffiths.
In Scotland it appears not to be unfrequent, having
been detected at Preston Pans, by Dr. Greville; at Souther-
ness, Kirkcudbright, by Sir William Jardine, Bart.; and at
Appin, by the late Capt. Carmichael. It is of annual duration,
and in perfection in the summer and autumn months.
