Monoecious, the antheridia and odgonia borne upon the same leaf- 
nodes, including that between the uncorticated basal and the lowest 
of the corticated leaf-internodes : about 25 cm. high, light-green, 
very slightly incrusted; stem 0,5-0.7 mm, in diameter, triply corti- 
cated, spine-cells s lender, 0.1-0.82 mm. long, or less often reduced 
- small papillae: stipulodes forming a double whorl at each node, 
those in the upper whorl 0.66-0.88 mm. long, considerably shorter 
than the uncorticated sae serene stipulodes of lower whorl 
0.38—-0.52 mm. long: leaves 8-10 in a whorl, I.5-2 cm. long, con- 
taining 7-9 internodes, = which ihe lowest one, the apical cell, and 
the internode next below i it are always or nearly always uncorticated, 
the remaining internodes triply corticated, uncorticated basal inter.
