of Linn, but besides the great difference in colour, {J. ciliaris being 
always of a rich yellow brown,) our present plant is much less convex in 
the upper surface of its leaves, which are divided into four narrower 
segments, and the laciniae are considerably longer, and more numerous, 
as well as greatly more branched. Hook. E.)
