 HAB. In spongy bogs. Southport (Holt 1882) ! ! 



Several other varieties have been named, but they seem rather forms due 

 to local conditions or season. The species may be distinguished from 

 A. glaucum by the leaves being smaller and not flexuose when dry, with a 

 stronger nerve and much shorter cells.

Dioicous ; stem elongated with few branches or paraphyllia, and
