has not the flattened thallus of our plant. Possibly it might be a 
form of G. australe J. Ag., a species that fruits freely. 
We alluded above toa fruiting —— of Pterocladia capillacea 
from Australia. It is preserved in the Kew Herbarium under the 
name of Gelidium pctrels and was i nGlected at Port Phillip Heads, 
Back Beach, Sorrento, Jan. 81st, 1890, by J. Bracebridge Wilson. 
It bears cystocarps of the Pter ocladia type, and this is, so far as we 
ow, the only fruiting specimen from Australia. On the same 
mount is a tetrasporiferous specimen, together with some sterile 
plants whi ch much resemble a specimen from Kiama, New South 
3N. This latter appears to us to be a tall lax form of P. capil- 
lacea, having a thin flat ribbon-like bi-tripinnate =. with fewer 
da more distant pinne. Harvey’s nos. 333 3338, which 
es i 
pict and were also issued as G. asperum, are simply G. 
austra 
It is a ioaake to be deplored that in De Toni’s Sylloge Algarum the 
— and almost historic species, G. corneum, has been allowed 
to pass out of existence—a fate which, in lichenological literature, 
has lec befallen the even more hoary and venerable lic snea 
barbata. There is comfort to Israel at least in the reflection that

the case of Usnea barbata to the scsiceratin of the Committee 
appointed by the recent Botanical Oongeans at Vienna to report on 
cryptogamic nomenclature. 
While treating of Pterocladia and Gelidium, we would take the 
paces of pointing out that, among the many pee of Gelidium 
figured by Kiitzing in his Tabule Phycologica, and not yet definitely 
steaed in current systematic literature, there can be no doubt that 
his G. cerulescens, op. cit. - p. 19, t. 56, c,d, from New Cale- 
donia, Wagap (Vieillard), and G. proliferum, tom. cit. p. 19, t. 55, 
a, b, from the Adriatic, are ayia s of Pterocladia caine,

common on the east coast—at all oviste, south of Sydney ; hence 
it is strange that neither Harvey nor De Toni mention it from the 
east coast at all, Our specimens are apparently more cartilaginous 
and narrower in the frond than those of West or South Australia.”

from deeper water ona cast up by storms. I am inclined to put it 
down as a deeper ph vegetative form of P. lucida. As far as 
I can make out, the structure of the frond is similar
