BARTRAMIA. 209 



Bridel has described this and other allied species as a 

 distinct genus, under the name of PJdlonotis, which recent 

 authors employ only to mark a subdivision. 



The var, marchica of Hooker, which is much smaller, with 

 lanceolate acuminate leaves, is regarded by continental bo- 

 tanists as a distinct species. It is found in similar situations 

 as the normal form, but not at such an altitude. 



5. Baktkamia calcarea, Br. et Sch, {Calcareous Ap- 

 ple Moss.) Leaves secund or subsecuud, crowded, ovato- 

 acuminate, longer and thick-nerved; perigonial leaves all 

 acutely acuminate, solid-nerved ; the smaller peristome com- 

 posed of remotely articulate teeth. — Mull. Sijn,p)t. l.p. 475. 



Moist, springy places, on limestone and basaltic rocks ; 

 fine in Teesdale. Fr. Summer. The secund direction of 

 the foliage, its larger size, and the more lanceolate form of 

 the individual leaves, are the chief marks of distinction from 

 the preceding. 



■^^ Seta very short, curved. 



6. Bautramia Halleriana, Hedio. {Hallerian Apjde 

 Moss.) Stems much elongated, proliferous ; leaves long, 

 subulate, flexuose, serrated above; seta lateral, from inno- 

 vations, very short, curved. — Eng. Fl. p. Q7 ; Miill. Syn. 

 pt. l.p. 495.
