WILLIAMS: CALYMPERACEAE OF NORTH AMERICA 375 
on both sides except at the denticulate apex, about one sixth the 
width of leaf at middle, in cross-section showing mostly four 
guide-cells, a stereid band much larger below than above and 
outer cells not differentiated; cells of upper part of leaf rather 
obscure, about 6 uw in diameter, densely papillose on both sides; 
cancellinae filling most of basal part of leaf, somewhat rounded or 
truncate above; outer perichaetial leaves much like the stem-leaves, 
the two or three inner much smaller, of mostly hyaline cells, 
often slightly serrulate; seta up to 5 or 6 mm. long, not quite smooth 
above; capsule erect, oblong, scarcely 1.5 mm. long, with convex- 
conical, rostrate lid about I mm. long; peristome-teeth golden- 
brown, not quite smooth, lanceolate, entire, projecting about 80 u 
above the rim of capsule with rather prominent articulations; 
spores rough, 12-14 w in diameter; calyptra not seen. [FiG. 7.]

Male flowers unknown: in compact, green tufts with somewhat 
branching stems up to 2 cm. high; stem-leaves with conspicuous, 
white, imbricate base, twisted and crispate in upper part when 
dry, up to about 3 mm. long, from an oblanceolate base with 
entire margin, usually one half to two fifths the length of leaf, ° 
gradually narrowed to a nearly linear, grooved point with distinct, 
entire, pale yellowish border not quite reaching the rather broad, 
toothed and apiculate apex which sometimes bears numerous 
spindle-formed or club-shaped propagula up to 100 » long, with 
six to eight cross-walls; costa usually smooth except on the more 
or less spiny-dentate back toward the apex, in cross section showing 
about five guide cells, stereid bands above and below, the upper 
band much smaller than the lower and the outer cells not differen- 
tiated; cells throughout upper part of leaf mostly rather obscure, 
highly mamillose or-papillose or sometimes almost spiny on both 
sides, the median about 8 u in diameter; cancellinae filling most of 
erect base of leaf, usually rounded above; inner perichaetial 
leaves much shorter than outer, about 1.5 mm. long, with very 
short, green, serrulate points; pedicel 4-5 mm. long, bearing an 
oblong capsule 1-1.5 mm. long with slender-beaked lid about one 
half as long; peristome-teeth golden-brown, lanceolate, nearly 
smooth, with rather distinct articulations, projecting above the 
mouth about 100 uw; spores rough, 14-15 u in diameter; calyptra 
rough in upper third. [Fic. 8.]
