Description. " Fronds numerous rising from a broad basal disc, 

 the basal portion is often almost cylindrical in older specimens, more 

 flattened and -compressed above, 10-30 cm high. The ramification is 

 divaricately dichotomous, often tri-polychotomous with widely patent, 

 recurved and entangled segments which have rounded patent axils. 

 Segments are compressed and linear being 1.5-2 mm broad or 

 cuneate beneath forks in upper -portion ; in some more widened into 5 

 mm or more in breadth and often thickening in the median line like 

 a costa. Terminal segments in some are linear as in lower portion, 

 ending in blunt or bifid apex or slightly broadened or much more ex- 

 panded with round apex. Margin is in some specimens subaequal 

 throughout, but more frequently is constricted at different distances. 

 Proliferations arise from glandular elevation along margin, also from
