Monoecious, ye antheridia and the odgonia at the same leaf- 
nodes: 3.5-4.5 cm. high, mo derately incrusted; stems 0.17-0.37 
mm, in eae entirely uncorticated below, above singly corti- 
cated, the cells not adjoining laterally, and therefore not completely 
covering the stem, secondary cortical rows not developed, though 
compressed into a single whorl, or entirely wanting: leaves 7 or 8 
in a whorl, 1-2 cm. ‘long, those at the lowest node uncorticated, 
nitelloid, not forming nodes and nod: usually composed of two

diameter ; mature sporocarps 0.9-1.1 mm. long, 0.56-0.6 mm. wide; 
odspores 0.54-0.6 mm. long, 0.4-0.42 mm. wide, with 8-10 striae;

Monoecious : resembling i in habit C. fragilis ui Gel2 but dif- 
fering very widely from it in the nature of the cortex and spine- 
at right angles to their length, rarely slanting ; spine-cells a 
scattered, projecting horizontally, or in the upper part of the inter- 
node weak, sloping downwards, conical, very sharp, 0.06-0.1 se mm. 
long, at the base eae mm. w ide (Braun’s description reads 
‘*1.05~-6 mm.,” supposed to be a misprint for preceding) : stipu- 
lodes forming a double whorl at ae node, more strongly developed 
than in C. fragilis, those in the er whorl somewhat longer as 
those in the lower, appressed respectively to the leaves ‘and t 
cending and straight, or slightly incurved, or the tip occasionally 
squarrose, about o.18 mm. in diameter, containing 4-6, usually 5,
