Hab. On rocky banks among mosses. At Glenmaluer, Co. Wicklow, 

 among tufts of Scapania resupinata, single stems. It will be 

 observed from the foregoing quotations, that considerable diver- 

 sity of opinion prevails regarding the position this plant ought to 

 occupy, whether as a species, or only as a variety of J. barbata. 

 L)r. Spruce's critical observations, which always deserve the great- 

 est attention, woiild appear to be decisive on the point, namely, 

 that it is a good species. He never found the true J. barbata in 

 the Pyrenees, thougb he found J. Lyoni.

 ' 2-ranked, spreading, ovate-lanceolate, bilobed, and cut at the- 



maro-in, lobes very unequal, sharp at apex. Involucral bracts
