Monoecious, the anth d borne upon the same leaf- 
nodes, the fee t at that a the first and second lowest corti- 
cated leaf-internodes: elongated, lightgreen, slightly inerasted 
fe o.7-1 mm. in diameter, very regularly triply corticated, t 
cortical cells very long, at least on ae internodes, the end si 
of the secondary cells very oblique, thus interposing a third cell 
between two consecutive primaries, though for a comparatively 
short distance; spine-cells 0.25-0.82 mm. long: stipulodes forming 
a double whorl at each node, those in the upper whorl 0.5-1.1 mm. 
long, usually slightly exceeding the Loenee este internode of 
the leaves, ee - pace baie -25-0. m. long: leaves 
10-15 in a whorl, 1.2 g, g, containing pie internodes, all 
baa corticated eceoe Wee tip nt the basal one, which are uncor- 
ticat ed , basal uncorticated internode much shorter than the suc- 
ally the Bees leaf uncorticated; leaflets at sterile nodes greatl 
reduced, mostly 0.08-o.2 mm. long, the anterior usually a little the 
longer, %  bracteoke the anterior ‘well developed, 0.96-1.4 mm 
long, e posterior very short, 0.0o8~o.16 mm. long, the antes 
rior fading about as far as the tops of the mature sporocarps, o 
often a little less, but overtopping immature sporocarps : catheridis 
0.42-0.47 mm. in diameter; sporocarps 0.85-1.25 mm. long, 0.5- 
0.65 mm. wide; odspores 0.57-0.68 mm. rong, oO. 35-0. 45 mm. 
wide, with 8-10 striae; whorl of crown-cells 0.19-0.23 mm. high,

nodes: 15-30 cm. high, pale-green, glistening, slightly incrusted ; 
stems 0.5—-0.75 mm. in diameter, som te t irregularly triply cor- 
ticated; spine-cells variable, o. ene Ban . long, with an extreme 
diameter at base of 0.07 mm. lipelodes “forming a core whorl 
at each node, those in the upper whorl 0.63-0.88 mm. long and 
0.08-0.1 mm. wide, slightly exceeding the Gees acued basal leaf- 
internodes ; stipulodes of lower whorl o. dna 49 mm. long: leaves
