250 NOTES ON CAREX. 



SO, his contention as to date will not apply, as Fries's plant is a 

 salina form. Richter puts tlie plant of Fries {Mant. in. p. 146), 

 Lang's boiralis, and Nylander's arctopJnla * under hyperborea Drej. 

 as a var. of aquatilis. He seems to ignore the Bat. Notiser descrip- 

 tion oi epiiit'jos Fries (1843), as he quotes the Summa (1846) for it. 

 But even if we admit Lang's plea, Fries had in his Mant. iii. 146 

 (1842), made a subspecies of C. ephjejos, and curiously enough, at 

 the same place, makes Wahlenberg's salina a var. of aquatilis. So 

 mixed up have these Carices been, that I may have fallen into error 

 respecting them. Blytt in Non/cs Flora simply calls C. epigejns 

 Fries a salina form, but neither there, or in his Nye bidrag of 1892, 

 does he mention C. boiralis Lang, though in the former he duly 

 quotes C. bolina Lang; yet Lang has " Norvegi^e " after iorfrtZ/s. 

 1 am inclined to think the Perth plant is ( '. arcuata Laest. ; but it 

 is impossible to be quite sure without seeing an authentic specimen. 

 C. aquatilis has been found in England (Lake Lancashire).! Most 

 of the specimens of Wahlenberg come between Nos. 3 and 4. 



X Carex Grantii Ar. Bennett, sp. n. C. aquatilis x kattegat- 

 ensis Fries. Growing with the two mentioned Carices on the Wick 

 river in Caithness. This is not 0. halophila F. Nyl., which Hjelt 

 refers to C. aquatilis x salina * cuspidata, though it has somewhat 

 the habit of that plant ; but the spikes of that are paler in colour, 

 longer, and the lower part generally attenuated, with longer 

 peduncles, and it has more an aquatilis look, while this has that 

 of salina. What C. vaccillans Drejer may be I do not know, but 

 Nyman puts it under Immalolcpis i)rej. as a subspecies. Almquist 

 says the Christiania plant is a form of C. kattegatensis Fries. This 

 plant of Drejer seems a very scarce form ; 1 have never seen a 

 specimen so named in any herbaria, and both Beurliug and Lang 

 say "mihi ignota." Nyman makes C. salinoides Beurling the same, 

 but Beurling says his plant is " (J. salina Hartm. ed. 5, non Wahlb. 

 Herb. Nor. f. 8, No. 72." I am unable to place C. Giantii with 

 any named form, aud suggest the above name after the discoverer 

 of kattegatensis in Britain. Greener than kattegatensis, with much 

 shorter spikes, less attenuated towards the base, shorter glumes, 

 green and paler, the first broader, aspect of the whole plant inter- 

 mediate between the two, with a tendency to salina ; this is not a 

 form of kattegatensis simulating aquatilis, as Almquist suggests one 

 of Nylander's does from (jsterbotten {But. Not. 128 note (1891) ), 

 but seemingly a hybrid, so far as it is possible to judge without 

 direct experiment. 



X Carex hibernica Ar. Bennett sp. n. C. aquatilis x (stricta) 

 Hudsonii. I have in vain tried to place this under some described 

 form ; in habit it strongly reminds one of C. Buekii Wimmer Fl. 

 Schl. ed 3, 81 (1857) ; but that has strongly webbed lower sheaths, 

 fruits inflated so as to project the tops of the glumes in a peculiar 

 manner, glumes much paler, narrower; the spikes attenuated
