Variable in size and colour, and also in the length and width of the 

 leaves. Lindberg refers Gr. Seligeri. to SeL setacea as a Var. pumila, yet in 

 W. & M. we find " A Grimm, recurvata foliorum figura, seta madida recta," 

 and have therefore followed Schimper on this point. 



3. SELIGERIA ACTJTIFOLIA Lindb. 



Autoicous ; resembling S. pusilla. Leaves more acutely subulate. 

 Capsule larger, scarce emerging above the elongated perichsetial bracts. 

 (T. XVI, I.)

 SeL pusilla Var. ft. acutifolia SCHIMP. Syn. 2 ed. 125 (1876). 



Autoicous, very small, deep green. Upper leaves and perich. bracts 

 from a more or less sheathing base, abruptly narrowed into a subterete, 

 setiform, very acute, fragile, crenulate subula, formed almost entirely 

 by the nerve ; cells all rectangular and pellucid. Seta very short and 

 slender, capsule small, the mouth scarce overtopping the apices of 

 perich. bracts, leptodermous, pale and pellucid, shortly pyriform with 

 a short neck, turbinate and wide mouthed when empty ; lid with a very 

 short, scarcely oblique beak ; teeth of per. short, rather obtuse. 



Var. ft. longiseta Lindb. 



Plant larger, with a longer seta elevating the capsule beyond the perich. 

 "bracts ; lid with a longer oblique beak.

The type of the species was first found in the island of Gotland, and 

 does not occur here; it stands intermediate between S.paucifolia and 5. pusilla, 

 agreeing with the former in the leaves and bracts, and with the latter in the 

 capsule ; a gradual transition into the. more elongated form takes place, but 

 all our British specimens have the rostellate lid. 



4. SELIGERIA TRIFARIA (Brid.) Lindb. 



Autoicous, densely caespitose, resembling S. pusilla, leaves in three 

 ranks, straight, lanceolate-subulate, rather obtuse, short ; capsule 

 thicker. (T. XVI, K.)
