broader at apex, median about 10:1, basal strongly porose ; quad- 
rate alar cells numerous, small, extending up the margin of leaf, 
densely chlorophyllose, 2-3 layered in the central alar area ; 
stem leaves larger and broader cells narrower and longer: dioi- 
cous; perigonial leaves oval, obtusely acuminate, ecostate; an- 
theridia large, inflated: perichaetium about 2 mm. long, loosely 
sheathing ; the inner leaves large, oblong, gradually narrowed 
above, obtusely acute, entire ; median leaf-cells linear, lower rhom- 
boidal. Sporophyte 2—2.5 cm. high; seta dark red-brown; 
calyptra dimidiate, long, descending to below the base of capsule ; 
capsule brown, erect, cylindric, 3 mm. long, 5:1; operculum conic- 
rostrate, beak often oblique; annulus of 2—3 rows of small cells ; 
peristome about 0.3—0.5 mm. long; teeth linear-lanceolate, red- 
brown, and closely articulate below, orange and distinctly articulate 
above, with a very distinct median line along which the tooth is 
often perforate or split; segments linear, as long as the teeth or 
longer; “basal membrane none;"

This species is quite common in Europe, but mostly sterile. 
It has been collected only twice in America. The nm 
specimens in the Columbia herbarium are all sterile and I s 
pect that all of Brandegee's and Waghorne's Seri, lacked 
fruit. The fruit is described from a European specim 
spores minutely roughened,
