 (o r ten 1.5 cm. broad), sparingly branched, 3-1 2 cm. high, about 3 

 mm. in diameter. Fronds arising subfasciculately from the ends 

 or sides of branches, flat, linear, 2-3 times distichously pinnate, 

 7-10 cm. high, 3-5 mm. broad in the broadest parts, a little 

 narrowed at the basal portion. Pinnae and pinnulae alternate or 

 scattered, often a few (3-4) arranged along one side, patent with

 measures 92-280 u. Cys to carps unknown. Stichidia, transformed
