2. Olive -green.
6. M. vermiciddris, Ag. ( Worm-like Mesogloia) ; brandies
irregularly pinnate thick vermicular linear-fusiform, ramuli
copious elongated flexuose resembling the brandies. Ag. Si/si,
Alg. j). 51 Rivularia vermieulala, E. JBot. t. 1818.— Uha
rubens, Huds. Fl. Angl.p. 571, (according to Mr, Arnott.)
Coasts of England, Scotland, and Ireland, in many places, common.
1— i feet high, the branches widely spreading, 1 2 lines broad, clumsy,
flexuose and attenuated towards each end. Substance firmly gelatinous
or sub-cartilaginous, elastic. " Whether we consider the character" U.
gelatinom filiformis ramosissima rubcscens, ramis spurns horizontalibus ob-
tusis," given by Hudson to his U. rubens, or rely on the specimen I possess
from Sir T. Frankland in Mr. Brodie's herbarium, and compared with
Hudson's plant, there can be no doubt but that species must be referred
to M. vermicularis." Arn.
7. M. Griffithsiana, Grev. MSS. (Mrs. Griffiths 1
Mesogloia);
brandies alternate or irregular very slender filiform long sim-
ple nearly bare of ramuli.
Sidmouth, Mrs. Griffiths,— 8— 1G inches high, of a pale rather olive
green, which becomes greener in fresh-water : frond subsimple, beset
throughout with very long, slender, simple, opposite or alternate branches^
its surface covered with long colourless byssoid fibres, similar to what
occur in ChordariaJlageUiformis. " Many fronds grow from the same base,
waving most beautifully in the water; and the long radiating fibres make
the plant appear much larger than it really is." Mrs. Griffiths , in lit!.—
The habit of this species is decidedly that ofChordariaJlagelliformis; a
plant which Mrs. Griffiths considers genetically allied to Mesogloia} in
which opinion I fully coincide, although I know I stand opposed to my
friend Dr. Greville and the bulk of Algologists.
8. M. viriscens, Carm. (greenish villous Mesogloia); branches
long erecto-patent filiform villose, ramuli numerous patent short
flexuose obtuse.
Appin, Capt. Carmichael. Sidmouth, Mr.;. Griffiths.— 8— 12 inches
high, olive-green, tender, >_ r clatiniis, slippery, excessively branched ;
branches long, simple or forked, furnished with numerous alternate or
secund, divaricating, flexuose ramuli. Frond to the naked eye appearing
Villose, owing t the filament- composing the periphery being VWJ
much protruded beyond the gelatine, and accompanied also by hyaline
fibres, similar to those of M. Griffilhsiana,
86. BATRACHOSPiRMUM. Ttoth. IJat radio. permum.

striated, composed of colourless jointed fibres agglu
