ADDITIONS TO THE FLORA OF THE ORKNEYS 171 



Ostenfeld calls the Faroese plant A. offidnalis ; but Nyman 

 and others refer it to A. norvegica, Rupr. I thought the Orkney 

 plant might be this, but Ruprecht 1 says, " A. sativa similis, sed 

 semina rotundiora." Then there is A. litoralis, Ag. in DC. = 

 Angelica litoralis, Fr. ; which Fries says in his " Flora Scanica," 1835- 

 1856, has "fructu inflate, nucleis liberis." These two seem native, 

 while the other seems to belong to a cultivated race, which may be 

 indigenous in East Europe and Russia. Mr. Spence writes that 

 the scent is very strong, and clings to the hands and clothes for 

 some time. He suggests the probable origin of the plant in Westray 

 as seeds from the Faroes, a fish-merchant in Pierowall importing 

 salted cod from these islands, which is brought in smacks direct to 

 Westray. 



NEW AND RARE MOSSES. 

 By JAMES STIRTON, M.D., F.L.S. 



IN continuation of my researches into the minute structure 

 of mosses, mostly in a barren state, wherein I attach 

 much greater importance to their areolation than has 

 hitherto been done, I have to record several which show, in 

 this respect, peculiarities of sufficient importance to warrant 

 their separation from those already known. As an illustra- 

 tion of this I shall describe here a curious moss. In this 

 instance the areolation of the leaf serves as the most im- 

 portant factor in its discrimination, more especially as the 

 general colour and, to a less extent, the habit of the plant 

 would lead one, at first blush, to associate it, if not to 

 identify it, with Rhacomitrium heterostichum. 



GRIMMIA FULIGINEA (n. sp.} In laxly aggregated tufts, at first 

 of a greenish yellow above, quickly assuming a tawny-yellow colour, 

 but of a dirty brown below ; stems upright from a half to one 

 inch in length, simple or dichotomously divided, but occasionally 

 emitting short irregular branches ; leaves closely arranged around 

 stem, somewhat incurved in a dry state, straight and nearly up- 

 right but flaccid when moistened, narrowly ovate lanceolate, 

 terminating in a long, nearly entire, hyaline hair, about half the 

 length of the leaf proper ; nerve also of a tawny -yellow colour, 

 narrow near base, latit., .04 to .05 mm., broadening somewhat
