Has. On a charred tree: Asbestos Hills, near Yorktown, Gunn. On rotten timber: Grass-tree Hill ; 
and on charred wood, in damp places, J. D. H, Common on the hills, New Norfolk, etc., Oldfield, Archer. 
These specimens, in colour and habit, as well as in the cireumstance of their growing upon charred wood, 
agree very nearly with that form of J. divaricata which was described by Dr. Taylor as J. exiliflora. When com- 
pared however with that species, they are readily distinguished by the leaves having a certain braided appearance ; 
the margins of the leaves are everywhere recurved; at the base, on the outer side, they are sometimes spinuloso- 
papillose, but the small teeth of the edges, from their downward direction, often present the same appearance when 
the papilla are absent. These different states are all found in European specimens. The J. sguarrosula, Taylor, 
from Swan River, is synonymous with J. divaricata. J. tubulata, Crypt. Antarct. t. 157. f. 6, differs in no way 
from ordinary states of J. bicuspidata. J. physocaula, Crypt. Antarct. t. 156. f. 1, seems to be very nearly allied 
to J. bicuspidata, but is more rigid; it has however no resemblance to J. concinnata. J. longiscypha, Taylor, 
from Swan River, is not different from J. setacea; also J. asperifolia, Taylor, from Madeira, is a slender form of 
J. dentata.

l. Plagiochila falcata (Hook. Musc. Exot. t. 89; G. L. et N. Syn. Hep. p. 649). 
Has. Tasmania, Gunn, Archer. Dense tufts, on rocks: Goat Hills; and on rocks, in streams, 
Kermandie Rivulet, South Huon, Oldfield. 
The stems of these specimens are 3 inches or more in height; the leaves erecto-patent and rather loosely dis- 
posed ; in the lower parts of the stems they are quite entire, but as they approach towards the apex they become 
more and more denticulate.

The Tasmanian specimens of this species are larger than any of those collected at Cape Horn, and have all 
their leaves entire; in every other respect they correspond so nearly that they may be supposed to be an entire- 
similar to those observable in several allied species, as P. falcata and P. retrospectans. The inflexion 
readily distinguishes P. Magellanica from its allies; the leaves themselves vary 
plants described as above, and referred to this 
leaved variety, 
of the dorsal margins of the leaves 
in being patulous or appressed, but their form is the same in all the 
species.
