terminal, very large in proportion to the size of the stems 
and leaves, bearing leaf-like scales; they are from a narrow 
base obovate. 
This species is readily distinguished from the Antarctic 
Jungermannia tetradactyla, Tayl, as well as from the Euro- 
pean J. setacea, and J. trichophylla, by the compound laciniz 
of the leaves ; besides, the stems and branches have a peculiar 
rugged and squamose appearance from the different direc- 
tions which the points of the crowded leaves and stipules 
assume,

Patches wide, shallow, brownish-olive. Stems from one 
to four inches long, irregularly pinnate, the branches set 
nearly at right angles. Leaves from a narrow base flatly

angulate top, lying closely adpressed to the inside of the 
upper lobe. | Peas 
This species is found abundantly in Ireland, and, ac- 
cording to Lindenberg, in Switzerland. It may be discri- 
minated from J. complanata, L. by the smaller size, more 
Convex leaves, their olive-brown colour, their lesser lobe not 
sharply reflected on the upper but having a tumid base, and 
by the deflexed perichetial leaves; besides the perigonia 
Occur usually at the termination of a shoot, and not on 
Proper short branches; the angulate portion of the lower 
is shorter than in J. complanata, L. In Ireland this
