Several fine specimens of this beautiful and well-marked species were 
forwarded. It is fairly frequent in the Magellan region, and the specimens 
from New Zealand and Tasmania, though differing slightly, appear to be 
referable to the same species.

One of the less satisfactory of Hooker & Harvey’s species, as the original 
‘gathering is mixed and the figure in ‘ Flora Antarctica’ is a composite one. 
The central figure must, I think, be regarded as the type, and the original of 
this is at Kew ; the smaller lateral fronds, the “ veinless varieties," evidently 
represent other specimens. The type is a strongly veined, very marked 
plant, and I have seen no other specimens which I could with certainty reler 
toit. The other 1842 gatherings named М. Smithii in the Kew collections 
are referable to N. laciniatum.

Judging from Hooker's specimens, the typical form of N. laciniatum has 
somewhat the outline of Callophyllis laciniata, but it varies from the 
blunt lobes of №. Bonnemaisoni to the deeply cleft, almost pinnately 
branched segments of №. laceratum. It appears to be not infrequent in the 
Magellan region, and is very closely allied to the last-named, from which in 
the sterile state it is almost impossible to distinguish it. The tetraspores are, 
however, scattered over the whole frond, and not confined to the margins or 
lateral proliferations. 
Several large specimens in Mrs, Vallentin's alge I have referred somewhat 
doubtfully to this species.
