Monoecious, the antheridia and oégonia occurring at the same leaf- 
nodes: 15-60 cm. high, lightly or moderately incrusted; stems 
.6-1.2 mm. in diameter, triply corticated; spine-cells often nu- 
papillae to slender cells nearly 2 mm. long: stipulodes oe a 
double whorl at ae node, those in the upper whorl 0.56-1.3 mm., 
most frequentl -o.8 mm. long, usually exceeding but not con- 
cealing the uncotiated basal internodes of the leaves; stipulodes of 
lower whor 2-0.84 mm. long, from one-half to three-fourths the 
length of he. corresponding stipulode of the upper whorl: leaves 
10-15 in a whorl, 12-35 cm. long, containing 10-20 internodes, the 
latter when mature ‘ints corticated, except always the basal one, "and 
rarely one or more at the apex, which are uncorticated; young leaves 
said to be sometimes aia uncorticate d; the uncorticated basal in- 
ternode 0.4—1 mm. long, and of equal or slightly less diameter ; leaf- 
lets at any sterile node ann D 0.17-0 m. long, those at the node 
between the uncorticated basal and the Peet of the sales inter- 
nodes similar to the rest, as bracteoles the anterior 0.7—-1. m. long, 
usually shorter than but sometimes a little exceeding the sporocarps 
the posterior much shorter but still well developed, 0.14-0. 
long: antheridia 0.38-0.56 mm. in diameter; sporocarps ee 
7 mm. wide; odspores long, 
0.4-0.5 mm. wide, with 11-15 striae; whorl of crown-cells 
high, 0.21-0.23 mm. wide at base, the individual 
cells lanceolate, nearly erect but not counivent. 
Type locality : Pennsylvania. 
Distribution: Pennsylvania to South America.
