more wide, divided into a few broad, forked, obtuse segments 
which spread at wide angles. Colour a livid purple, resem- 
bling that of some Porphyre, but not so glossy. The hue 
of this species is sufficient to distinguish it from all others, 
except N. Gunnianum of Tasmania, but the substance of 
that plant, the fruit of which is unknown, is very much 
thicker and less lubricous.

' The specimens of this plant are very much torn and bat- 
tered, but sufficiently perfect to show that they belong to a 
new and distinct species. The stems are from one to three 
inches long, and either simple or irregularly branched; the 
branches terminating in fan-shaped fronds, cuneate and 
somewhat veiny at the base. They are of a thick substance, 
veinless above, and have a dull brownish-red colour, darker 
than that of any other species known to us. The sori of 
granules are exceedingly small, sometimes so much so, as fo 
be reduced to nearly solitary spherospores which are densely 
powdered over the whole frond. "The nearest affinity of this 
species is with N, ulvoideum, Hook. (N. Hillie, Grev.) from 
which it abundantly differs in colour, in the very remarkable 
and often extensively branched stem, the much more nume- 
rous capsules, and so far as we can judge, in outline also.
