The very large, transversely oblong and closely imbricated sti- 
pules will readily distingush this species from any other with which 
I am acquainted. I think I am correct in considering it to be the 
J. Billardiert of Schwaegrichen ; his words being “ J. caule 
erecto subramoso, foliis imbricatis ovatis acutis omni margine 
serratis, stipulis arcuatis dimidio minoribus ;?’—and I am the 
more inclined to think them one and the same plant, because 
M. La Billardiére has given me very fine specimens, which he 
gathered in Van Diemen’s Land, of the same species, but with- 
out a name.
