 compressed stipe attached by a simple discoid holdfast ; branching essen- 

 tially dichotomous throughout, at intervals of 1-2 cm, in middle and 

 lower parts, somewhat divaricate, the fronds flabellate and ± sym-

 much broader at the dichotomies, sometimes to 2-3 cm. broad where 

 several segments join in mid-parts; ultimate segments very short, ter-
