BRITISH JUNGERMANNI2E. (J. reptans.j 
The species here figured and described, which scarcely yields in beauty to any one of the 
genus, may be considered as one of the most universally dispersed throughout Europe. In habit, 
it is closely allied to J. trilobata, having, like that plant, its leaves imbricated on the upper surface, 
large dentate stipules, flagella beset with leaf-like scales, and a whitish membranaceous calyx, 
proceeding from the under side of the stems. The var. /3, though differing at first sight so 
materially from a, is distinguishable only by its great size and bipinnate ramification. The 
extremities of the uppermost pinnae, indeed, are almost always obtuse ; those of the lower ones 
attenuated. This var. is rarely found in fructification. Miss Hutchins alone having been so fortunate 
as to meet with it in that state.
