Plants to 10 cm tall, dull pink, somewhat fleshy, somewhat clustered, 

 the main axes sparingly alternately branched, the branches cylindrical and 

 firm below, but above expanded to 2-3 mm in width and flat, rather freely 

 marginally alternately branched, the lesser branches becoming like the 

 axis, linear lanceolate, the margin because of the presence of the next 

 junior branch rudiments appearing serrate; tetrasporangiate branches 

 acute, terminating the divisional series in pinnate fashion, fertile in the 

 ultimate and occasionally the penultimate segments, which are 250-375 /i 

 diam., 1.5-2.25 mm long, with the sporangia mostly midway of the
