At Tas. LX. of this work is given a Jungermannia, (J. pen- 
dulina) which is only to be distinguished from J. reptans by the 
different mode of growth and ramification. The present plant 
altogether resembles that in its size, mode of growth, and rami- 
fication ; yet the extreme minuteness of the leaves and stipules, 
and the distance at which these are placed from one another are 
so striking, that none would perhaps hesitate at first sight in pro- 
- houncing it distinct. But when these differences are pointed out, 
(and they are very constant in all the specimens which I possess,) 
nearly all that fford marks of discrimination between the pre- 
sent plant and J. pendulina are mentioned; for, on subjecting the 
leaves of the former to a high power of the microscope, they will 
be only found to differ from those of the latter in their extreme 
minuteness, their more quadrate figure and nearly plane surface. 
The specimens which I have received from Guadaloupe are 
smaller, and of a paler and yellower green, but are like those of 
Mr. Menzies in every other particular.

by some authors to J. setacea.
