the clasping base; stem-leaves about 3.5 mm. long, the obo- 
vate sheathing base 1.5 mm. long with a nearly linear limb ob- 
tusely pointed ; perichaetial leaves very similar to stem-leaves 
but with somewhat larger loosely clasping base and up to § 
leaf-margins serrulate to or near base with a 
thickened, terete border in upper part; costa just above base 
80» wide, vanishing several cells below apex of leaf and 
often bearing on its upper side near termination a small 
cluster of oval to nearly cylindrical propagulae; leaf-cells 
above mammillose, about 6 in diameter, the band of 
elongated, narrow cells (teniola) near margin of lower leaf 
not extending into upper limb; hyaline cells more or less 
rectangular, from nearly square to twice longer than broad, 
often 30 wide toward costa and occupying most of lower 
limb, with green cells extending downward a short distance 
on either side of costa and at margins: seta about 
long; capsule oblong, 2 mm. long, with conical-rostrate lid 
.75 mm. long; calyptra persistent, plicate, scabrous above: 
spores nearly smooth, up to 20 y in diameter.

Weisia tortivelata sp. nov. 
Apparently dioicous. In cespitose, rather light green tufts 
with stems u hi ong, 
crispate when dry, erect-spreading when moist, the peri- 
chaetial from a pale somewhat enlarged base, long linear- 
lanceolate with flat margins, acute apex and costa very short- 
excurrent, those of stem similar but shorter with scarcely 
enlarged base; leaf-cells small, obscure, papillose above, 
rectangular, nearly hyaline below: seta pale yellow, up to 2 
cm. high; capsule nearly straight, cylindrical, not furrowed 
when dry, up to 2 mm. long, with rostrate lid about one half 
as long; annulus large; peristome pale, short, irregular; 
calyptra cucullate, twisting.

Weisia longidentata sp. nov. 
Synoicous or monoicous. In cespitose rather light green 
patches with stems about 2 mm. high: leaves crispate when 
dry, up to about 2.5 mm. long, from a somewhat larger, 
nearly hyaline base, almost linear above, with incurved 
margins, acute apex and very shortly excurrent costa; leaf- 
cells above small, obscure, papillose, below rectangular, up
