454 HEPATICH ANTARCTICAE. 
George Town, V. D. L., R. Gunn, Esg., n. 1318 ?—A single 
imperfect specimen marked with a query is all that I have 
seen (n. 1318 is Pol. cancellata), but this is sufficient to es- 
tablish a perfectly distinct new species. This specimen, 
which consists of the upper portion of a frond, is 6 inches 
long, and half a line in diameter, solid, cartilaginous, with a 
percurrent stem, much branched alternately ; the branches 
and their divisions not strictly distichous, though nearly so. 
Branches long, simple, patent, alternate or secund, laxly set 
with alternate elongated simple ramuli, which bear a third 
and probably occasionally a fourth series similar to them- 
selves. All the ramuli more orless tapering at base, and 
very acute, or acuminate at the apices. Warts of fructifica- 
tion rather laxly scattered over the branches and ramuli, 
depressed, exactly elliptical. Colour olive green.
