nata of Lamouroux, beng possibly a synonyme. Be this as it may, 
species of Bryopsis have been found in all parts of the world, 
and they resemble each other so closely, that except in a few 
instances it is very difficult at all times to determine to what 
particular doof species individuals should be referred. 
Though having all the softness of texture and brilliant green 
colouring of the Conferve, the Bryopsides must be regarded as 
holding a still lower rank in the Vegetable Kingdom, and ap- 
proaching very nearly to those organisms that seem uncertain 
under which banner to arrange themselves, whether Animal or 
Vegetable. Viewed by itself indeed Bryopsis plumosa appears as 
perfect a vegetable as any, but taken in connection with neigh- 
bouring nearly alhed structures Dasycladus, Caulerpa, Polyphysa, 
Halimeda, Struvea, &c., tt is found to approach much more closely 
to the confines than would at first sight be supposed. 
The first notice we find taken of this elegant plant is by Hudson 
in whose ‘ Flora Anglica’ it appears under the specific name by 
which it is most generally known.
