Great Coco, in wet places in the interior with Gyperus elegans. 
Cosmopolitan in the tropics. 
When discussing the weeds of the Andaman Flora {Jour. As. Soc. 
Beng.) the writer imagined this fern to have been introduced into these 
islands by human agency, at least indirectly. But the Coco locality 
proves sufficiently to his mind that its presence is altogether iadepen- 
dent of man’s presence, and he has since then collected it in similar 
situations in South Andaman. It is probably not at all common how¬ 
ever, and hence it had escaped the notice of Mr. Kurz when he collected 
in the Andamans.
