BRYUM. 323 



9. Bryum uliginosum B. & S. (Cladodium uliginosum Brid. ; 



Bryum cernuum Lindb., non B. & S., Braithw. Br. M. Fl.) 



(Tab. XLIII. H.). 



Somewhat resembling B. inclinatum ; the innovations more 

 slender, with laxer leaves, the comal tufts less distinct. Leaves 

 much resembling those of B. inclinatum, but less narrowly 

 pointed, with the nerve more shortly excurrent ; border 

 thickened, of 2-3 layers of cells ; and recurved. Seta long, i\ 

 inches, capsule inclined or pendulous, oval-pyriform, incurved, 

 and gibbous at back, pale brown, neck long, narrow, distinct, 

 tapering; mouth small, oblique, lid convex, acute; peristome 

 teeth pale yellow, not orange at base, densely barred ; cilia 

 absent or rudimentary. Autoicous ; male flower gemmiform, 

 below the fertile flower. 



Hab. Bogs and damp sandy places. Rare. Fr. late summer. 



The asymmetrical, curved and gibbous capsule, with the small mouth pointing 

 obliquely downwards, together with the long neck and the imperfect inner peristome, 

 form the best marks by which this species may be known. The shape of the capsule 

 is not unlike some forms of B. pattens, but that species wants the small, oblique 

 mouth, and the peristome is perfect. The thickened leaf-border is another good 

 character, but not a very easy one to observe, as this can only be done by careful 

 section cutting. The habitat, moreover, is usually a safe guide, as compared with B. 

 inclinatum ; the peristome teeth are also less thickened at the base than in that and 

 most species, and are consequently little or no deeper in colour there than above, so 

 that the species is in some degree intermediate between this Section and the following 



10. Bryum fallax Milde (Tab. XLIII. I.). 



Closely resembling certain forms of B.pallens ; leaves rather 

 wider and shorter, very shortly pointed, with a very narrow not 

 thickened border ; capsule pendulous or inclined, pyriform, with 

 a long neck becoming plicate when dry ; outer peristome as in B. 

 pallens, inner adherent to the outer, cilia none or very rudi- 

 mentary. Dioicous. 



Hab. Damp places, very rare ; Sussex and Snowdon (Mitten). Fr. late 

 summer. 



This species comes very close to B. pattens, but is separated by the non- 

 thickened border of the leaves as well as by the imperfect inner peristome. 



D. LEUCODONTIUM. 



[The species comprised under this Section form a natural 

 group, marked by the peristome, which has perfect appendiculate 

 cilia as in Eu-Bryum, but the outer teeth instead of being orange
