stem. Cuticular cells of both in one layer, only here and 

 there a cell is divided lengthways. Leaves of divergent 

 branches large, up to 2' 14 mm. long, and below the middle 

 about 1 mm. wide, from a narrow base widening to the middle, 

 then gradually narrowing to a wide, truncate, toothed, 

 cap-shaped apex, closely imbricate or squarrose, when 

 dry faintly shining; margins denticulate and bordered by 3 — 4 

 layers of narrow cells. Hyaline cells very fibrose, those on 

 the upper half of the inner suface of leaf having medium- 

 sized pores, especially where several cell angles meet ; nearer 

 the margins the pores are solitary and small, whilst the base 

 is poreless ; on the apical half of the outer surface pores very 

 numerous in rows at the commissures, slightly ringed, round, 

 to half-round, medium to small, in the basal part only small 

 angle pores. Chlorophyllose cells in section elliptic, central, 

 enclosed by the hyaline cells on the inner surface, but free on 

 the outer, where the walls are mostly smaller, strong, and 

 thickened. Leaves of the pendent branches appressed, lance- 

 olate, with hyaline border towards apex ; areolation much 

 laxer ; on both surfaces the hyaline cells have numerous 

 much larger, delicately ringed, pores. Chlorophyllose cells 

 trigonous-oval, nearer the outer surface, and here free, but 

 enclosed at the inner surface by the hyaline cells,

Dioicous ; in dense, soft, turgescent tufts, sordid green, 

 scarcely shining. Stem to 2 cm. high, erect, densely leaved, 

 sparingly radiculose at base ; innovations few, erect, strict, to 

 8 mm. high, densely leaved, rather acute. Leaves all nearly 

 equal, when dry imbricate, when wet patent, soft, very con- 

 cave, not decurrent, Joblong, somewhat obtuse, l - 5 — 1*7 mm. 

 long and 0'5 — 0'6 mm. wide, not quite entire, not limbate, 

 margins erect, revolute at base on one side only ; nerve stout, 

 tr06 wide near the base, lufescent, red at base, vanishing 

 below the apex ; cells in the middle of the leaf rhomboid- 

 hexagonal, 0-050— 0-060 mm. long and 010— 0-015 mm. wide, 

 the basil rectangular, the lowest inflated, purple. Perichaetial 

 bracts ovate, acuminate, the innermost smaller, from a dilated 

 base gradually acuminate. Seta to 13 mm. high, geniculate- 

 ascending at base, cygueous at apex, thin, purple, not shining, 

 not twisted when dry. Capsule pendulous, oblong, with short 

 thick neck, when dry rugose, 2 -25 mm. long and 1 mm. thick, 

 symmetrical, not constricted below the mouth, purple, not 

 shining; annulus broad, revolute ; peristome as in Br. alj>inum,
