Has. Tasmania, Mr. Gunn.—Frond 8-19 inches or more 
in expansion, with a very short stem, which is rapidly dis-

Has. Tasmania, Mr. Gunn, (1335). This has a very PE 
culiar aspect, owing to the great difference in breath? — 
between the branches, and the pectinate ramule which 
they bear; but the ramulification is essentially the same 
as that of the common state of P. coccineam, which every 
one allows to be a very variable species.
