variable size and shape, at the extreme their length greater than 
the diameter of the stem: stipulodes forming a double whorl at 
each node, well developed, resembling the spine-cells, those in the 
upper whorl generally somewhat longer than those in the lower: 
leaves 8-11 in a whorl, 0.5—10 cm. long, containing 5-7 internodes, 
doubly corticated except usually one, more rarely 2 or even 3, termi- 
nal internodes, which are uncorticated, the leaf-tip 1-3-celled; leaf- 
lets variable, at sterile nodes the posterior not or only slightly shorter 
than the rest, as bracteoles the lateral the longest, fae from less 
than the length of the sporocarps to ten times the length of the 
latter, the posterior from mere papillae to almost the length of the 
anterior: antheridia o.5—o.8 mm. in diameter, rarely less than 0.55 
mm. ; sea large, ovate to ovate-globose, with a maximum 
length of 1.3 mm. and width of 0.8 mm.; odspores without cal- 
careous cea. black or brownish-black, . 4¥-0.86 mm. long, 
0.45-0.5 mm. wide, with 11-14 striae; whorl of crown-cells about 
0.24 mm. high, 0.22 mm. wide, the individual cells oblanceolate. 
Type locality: Scandinavia. 
Distribution: Greenland; shores of the Baltic and England. 
Braun says that the Greenland plant has greatly elongated inter- 
nodes, short leaves, and small spines.
