buscula; and a short time afterwards Miss Turner supplied me 
with a fine specimen that at once convinced me that the plant 
was different from D. arbuscula, but left me in doubt whether it 
ought not to be referable to the D. corymbifera of J. Agardh. 
Of that species I possess a small morsel on talc, and as far as I 
can decide from an imperfect fragment, our plant is different ; 
and it is also abundantly different from any other Dasya with 
which I am acquainted. In the byssoid fineness of its ramuli it 
approaches D. elegans, but differs in habit and in the form of its 
stichidia and ceramidia. The habit of our new plant is indeed 
rather that of Pol. byssoides or of Setrospora Grifithsiana than of 
any Dasya known to me, and may be said to be mtermediate in 
aspect between those two beautiful plants. The conical outline 
is very characteristic; but it is on the extreme slenderness and 
repeated division of the ramuli, and the shape of the stichidia 
that I chiefly rely for its diagnosis. 
I am much indebted to Miss White and Miss Turner for 
specimens of Jersey Algze, and I would willingly discharge a 
portion of the debt by imscribing the present beautiful plant with 
the name of its fair discoverer, could I determine to which of the 
ladies the merit belongs. But as this point is doubtful, I have 
chosen a specific name which is at the same time descriptive of 
the elegance and grace of the plant and, in its derivation, allusive 
to the fairer portion of creation in general.
