Asia-Tropical: India present; Maluku (Maluku present); Philippines (Philippines present); Thailand (Thailand present), Carolines present, Ceylon present, Halmahera present, Java only in the western part present, Lesser Sunda Is, Luzon present, Melanesia present, Micronesia present, Mindanao present, Pacific: Fiji (Fiji present), Ryu Kyu Islands present, Solomon Is present, Southern America: Argentina Northeast (Formosa present)
From India and Ceylon to Thailand, Indo-China, Formosa and the Ryu Kyu Islands, Micronesia (Carolines) and Melanesia (Solomon Is., Fiji), almost throughout Malesia, but often very local; in Java only in the western part, in the Philippines only known from Luzon and Mindanao, in the Moluccas only from Halmahera; not yet collected in the Lesser Sunda Is. Distribution map in .


Sometimes used for making bags (Sumatra E.C., W. Borneo).


Except for some minor points the collection KALKMAN 4003 from W. New Guinea, Sibil valley, very well answers the description of E. difformis , of which I have not seen the type. Similar slender specimens with stems not fully 1 mm wide I have seen from the Malay Peninsula and Borneo. In my opinion they are not specifically distinct from E. ochrostachys, and I doubt whether E. difformis can be upheld.
