WILLIAMS: CALYMPERACEAE OF NORTH AMERICA Stl 
inner ovate, acute, not quite entire, the outer longer with pale, 
lanceolate, serrulate point, enclosing five or six antheridia a little 
over one half mm. long with somewhat longer paraphyses: in 
large, not very compact, greenish brown tufts, with more or less 
curved, branching stems, tomentose below, up to 4 or 5 cm. high; 
stem-leaves spreading-flexuous, up to 6 or 7 mm. long, from an 
oblong-ovate, mostly golden brown base about 1.5 mm. long, 
slightly crenulate or serrulate on borders, gradually narrowed to a 
linear-lanceolate point, tubulose when dry, with thick, doubly 
serrate margins and acute apex; costa not quite percurrent, 
serrulate on back toward apex, smooth below, one half up about 
one sixth the width of leaf, in cross-section showing six or seven 
guide cells, large stereid bands above and below and outer cells 
differentiated; leaf-margin in cross-section triangular, showing a 
stereid band surrounded by rather large outer cells; cells through- 
out upper leaf mostly slightly elongate, the median about 6 u wide 
by 7-8 u long; cancellinae filling a rather small part of leaf-base, 
mostly broad and rounded or truncate above; inner perichaetial 
leaves scarcely smaller than outer; seta 10-18 mm. long; capsule 
ovate-oblong, small-mouthed, about 2 mm. long with a slender- 
beaked lid 1.5 mm. long; peristome teeth projecting above the 
mouth about 75 u, often united to near apex, rather pale, with 
often numerous, golden brown, wart-like projections over the 
outer surface; spores rough, 18-24 uw in diameter; calyptra rough 
hear apex. [FIc. 2.]

Dioicous: in compact cushions, greenish brown above, rusty 
brown within, with more or less fasciculate branching stems, 
somewhat tomentose below, up to 3 cm. high; stem-leaves incurved 
or crispate when dry, the upper 4.5-5 mm. long, from an ovate 
base about 1 mm. long, somewhat narrowed to a nearly linear 
point three and one half to four times longer with incurved, 
doubly serrulate-lamellate borders and broadly acute or obtuse, 
serrulate apex; costa not quite percurrent, about 80 u wide half 
way up the leaf, mostly densely covered on the back, from the 
middle to the broadened base of leaf, with high, almost spine-like, 
papillae; leaves in cross-section near middle showing a terete 
costa with five or six guide-cells, large stereid bands above and 
below and outer cells differentiated; leaf-blade with cells highly 
Mmamillose on upper side, nearly smooth or somewhat mamillose
