when moist, obliquely ovate, .45-.7 mm. x .4-.62 mm., arching 
over the stem and subtruncate at base, entire, the slightly decurved 
apex rounded-obtuse ; lobules inflated and broadly galeate, .16- 
.18 mm. long, .2-.27 mm. wide, separated from the stem by about 
one fourth their width, or very often imperfectly inflated or wholly 
explanate, then ovate-linguiform, .18~.3 mm. long, .1-.18 mm. 
wide; stylus subulate, minute: underleaves distant or contiguous, 
plane, broadly rhombic or rhombic-obovate, mostly 1-2 times the 
width of the stem, bifid 14—14 their length, with obtuse or sub- 
acute lobes and sinus, entire or more commonly unidentate on the 
sides: superior and median cells of the dorsal lobes 16-30 м, all 
with slightly thickened walls, small trigones, and no intermediate 
thickenings : autoicous: androecium small, ovoid, occupying a 
short branch springing from near the involucre, 4 bracts 1-3 
pairs: archegonia about 6, terminal on Ше stem or the principal 
branches; 9 bracts in two or three pairs, gradually larger than 
the leaves, unequally bifid, the dorsal lobes ovate, entire or sub- 
crenulate toward the base, obtuse; lobules shorter and narrower, 
ovate, obtuse or subacute, bearing a single distinct tooth or seg- 
ment slightly above the middle of the inner edge, otherwise en- 
tire : bracteole oblong or narrowly ovate, connate on one side with 
bract, bifid for 14 or more of its length, with lanceolate parallel 
or somewhat divergent lobes, otherwise entire or sometimes uni- 
dentate toward the base of the free margin: perianth about half- 
exserted, broadly fusiform to obovoid-pyriform, 1.4-1.8 mm. x 
.75-1.1 mm., with a distinct two-angled ventral keel and one or 
more less pronounced dorsal and ventral ridges, gradually nar-
