 Sterile whorls of about 6 rather stout simple branchlets. 

 Fertile whorls forming rather large dense heads. 

 Branchlets once or rarely twice forked, the basal cell 

 short, with usually 2-3 short incurved 3-4-celled 

 lateral rays and a much longer 3-5-celled terminal 

 ray ; cells of rays rounded at their extremities ; ultimate 

 cell often short and when elongated sometimes much 

 narrower than the cell below. Oogonia clustered at

 c. 500-575 /x long, 450-500 /x. broad ; spiral-cells show-
