TWO NEW PLANTS 
This plant does not appear to be unfrequent in the Fritl^i 
of Forth. Early in March 1821, I found it, in company 
with Mr Arnott, on the Black Rocks at Leith ; it grew 
there at the bottom of small pools left by the tide at almost 
low water-mark. I have since found it more sparingly be- 
tween Newhaven and Caroline Park, midway between high 
and low water-mark, on rocks, and intermixed with young 
plants of Edocarpiis littordlis. 
Glqipnema contains a small number of very extraordinary 
plants, v/hich have puzzled every naturalist who has touched 
upon them. Of the two latest writers, Agaedh and Lyng- 
3YE, the former has been most successful in establishing a 
good generic character: his own observation it may be; 
worth while to transcribe. — " Species vere singulares et 
loco dubias continet hoc genus ; neque satis scio, an revera 
tres illae, quas hue congessi, unius ejusdemque generis sint, 
cum non nisi unicam viyam vidi, reliquas duas tantum sic- 
catas. Multa tamen communia habent, sed adhuc dubium 
comprimere nequeo^ an Gl. paradox um sit vegetabile, nec 
ne." — Aq. Syn. Alg. Scand. p. xxxv. 
Agardh has only described three species, GL para- 
doocum^ Gl. chtlionoplastes^ and Gl.Jwtidum [Conferva foetu 
da of DiLLw yn). Of these, the first and the last I suspect 
can only be retained ; the other {Conferva of the Flora 
Danka and Dillwyn, and Oscillatoria of Vaucher and 
Lyi^gbye), whatever genus it be referred to, must be ex- 
cluded from Ghionema. Mr Gray, who, from the prodi- 
gious number of new genera he has himself, or in conjunc- 
tion with others, mamifactured in his late work, stands some 
chance of having a few of them adopted, has, from this sin- 
gular plant, constituted a new genus, under the name of 
Yaginaria^ a distinction which it seems really to deserve.
