cially of Australia, yield beautiful species, having the pinnated
habit of Corallina with the antennated fruit (if so I may call it)
of Jania. These form the section of Jania, called Ilaliptilon
by Decaisne, and I have already figured, on CoraUina squamata,
fruit which, did it occur on an Australian specimen, would entitle
the individual furnished with it to a place in the subgenus Hali-
ptilon.
Jania corniculata differs from the more common J. rubens chiefly,
if not altogether, in the form of the lower articulations ; much as
Corallina squamata differs from C. officinalis. The species has
been generally kept up by all authors, since the time of Ellis,
who first distinguished it. On the British shores it is most common
on the southern coast, while J. rubens is found all roffnd
the island.
