Tortula petriei, sp. nov., " a congeneribus foliis late flavo- 



limbatis facillime dignoscenda," Broth. Plate XXV. 



Synoicous, in dense patches, stems short, 0-3in. long, 

 simple or dichotomously branched. Leaves at base of stem 

 small oblong ovate, above ovate-lanceolate tapering gradually 

 to apex, upper part near apex finely but irregularly serrate, 

 olive-green ; border continuous from base to apex consisting of 

 long blunt-ended cells, 0-0037 to 0-004 wide, orange-yellow ; 

 nerve rufous, stout, excurrent in a short stiff mucro ; cells at 

 the base rectangular, yellowish, gradually merging into small 

 roundish hexagonal opaque chlorophyllose cells. Seta nearly 

 lin. long, red, smooth ; capsule 0-2in. long, cylindric, slightly 

 curved, smooth, reddish-brown. Peristome, tube dull-red, 

 obscurely tessellated, 0-06in. long, teeth one-third length of

A very handsome species, well marked by the very striking 

 yellow border to the leaves.

 nervo excedente mucronatis differt," Broth. Plate XXVI. 

 Synoicous, in small cushioned tufts. Stems 0-3in. long, 

 fastigiately branched, fuscous and radiculose at base. Leaves 

 when moist patent, ovato-lanceolate, stout, margins flat 

 entire; nerve brown, very strong, excurrent, in a stiff mucro;

 broadly oval ; mouth small. Peristome single, of 8 bigemi- 

 nate blunt obtuse teeth ; operculum short, conic, apex slightly
