Fissidens (A/oma) macroblastus sp. nov. 
Evidently dioicous. Fertile plants about 2 mm. high, 6- 
or 7-leaved; the upper leaves 1 mm. long, oblong-lanceo- 
ae acute, entire or somewhat crenulate, smooth and without 
border, nerve vanishing 4 or 5 cells below apex, sheathing 
lamina extending scarcely one half up, dorsal lamina broad 
above, gradually narrowing to stem; leaf-cells often some- 
3 / 
long, with erectly rostrate lid about as long; calyptra nar- 
rowly mitrate, not split, covering beak only; teeth of peri- 
stome abruptly bent outward at base, then incurved, on falling 
of lid, split scarcely one half down, the forks very unequal 
and filiform; exothecal cells mostly nearly square, 16p 
wide, with walls sinuous from the abrupt thickenings, es- 
pecially in angles, cells just under the mouth smaller, but 
not transversely elongated, those of the lid with interior area 
much less than that occupied by the greatly thickened walls ; 
annulus none: spores up to ro

Moenckemeyera obtusifolia sp. nov. 
Stems simple and appearing dioicous or with a fruiting 
branch just under the male flower and thus autoicous, up to 
8 mm. high with about 13 pairs of leaves imbricated above: 
lower leaves very small and somewhat acutely pointed, above 
up tor mm. long, oblong-linear or slightly lanceolate with 
mostly obtuse apex ; clasping part of leaf extending a little 
above the middle with its apex ator near costa; dorsal lamina 
as wide above as ventral, usually gradually narrowing to 
base of costa; leaf-cells anion 6—8 # in diameter, mam- 
millose, forming a crenulate margin all round, or sometimes 
the clasping part with cells in margin elongated, forming a
