Bryum erythrocarpon Var. limbatum Berthoumieu Rev. bryol. 1883, P- 67. 



Dioicous ; stems short, in rather loose tufts, rufous at base. 

 Leaves dull yellowish green, ovato-elliptic, acuminate, faintly serrate at 

 apex or entire, margin plane with a narrow yellowish limb of 3 — 5 rows 

 of extremely narrow linear cells, the rest being firm, hexagonal with thin 

 walls, the basal hexagono-rectangular ; nerve reddish, excurrent in an 

 apiculus ; perich. bracts smaller than the leaves, narrower, with a more 

 distinct border. Seta red, variable in length ; caps, cernuous, clavate- 

 oblong, rusty red, lid large, brighter red, shining, shortly conical with 

 an acute apiculus ; teeth of peristome small, attenuated in the upper 

 half. Male plants short, the infl. terminal. 

 Hab. — On the ground, not common. 



Hurstpierpoint and Maresfield, Sussex {Mitten 1849) ! ! 



This moss appears to be specifically distinct by its bordered leaves, 

 though coming near to B. erythrocarpon, in fact B. hicolor, erythrocarpon, rubens, 

 murale and marginatum form a very closely allied group, which may be 

 connected by intermediate forms. The present species may belong to 

 B. radiculosum of Bridel, but it must remain doubtful as he does not describe 

 the border to the leaf. The leaf-cells are wider than in B. erythrocarpon, and 

 according to Mr. Mitten it is found in central Europe, N. Asia and 

 N. America.
