perigonial bract 2* mm. x 75 mm,, segments 1"25 mm. ; antheridia 

 •275 mm. x "175 ram., bearer -275 mm. x -03 mm. 



Hab. — Grows in dense tufts on exposed banks or crags in 

 alpine or subalpine situations. Moderately rare, but often grow-

Found on tlie Continent and in North America. The large 

 form H. junipenna (Sw.) in the West Indies, South America, 

 Africa, Madagascar, Java, &c. 



Obs.— This is a very distinct species and not likely to be con- 

 founded with any other British hepatic. It varies extremely in 

 size from an inch or so to 5 and even 6, and in colour from a 

 reddish to a dark brown. 



Herberta j unijjerina (Sw.) is usually a more robust plant with 

 larger leaves, broader at the base, often more ventricose, margin 

 at the base distinctly dentate ; Hooker may probably be right in 

 considering //. adimca only a variety of it. 



I have never seen male or female of //. adunca, so have described 

 and figured those of H. juniperina from Cuban specimens, which I 

 have little doubt will be similar or nearly so to those of H. adunca. 



llerherta Sauteriana (Hiiben.) {Ilerberta straminea, Dum.) has 

 been reported from Scotland, but all the specimens I have seen 

 under this name are to be referred to H. adimca. 



Herherta Sauteriana (Hllben. ), which is found on the Continent, 

 has a different habit, leaves close, shorter and broader, coarsely 

 dentate at the base, with segments shorter and broader.
