Notes
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.
