M. tuberosa Jack “rumphii” a new 'combination' (well sort of) published in the C. R. Huxley & Jebb revision in Blumea 37 (2) p281, (1993).



However, non lumpers might prefer M. rumphii Becc., (Odoardo Beccari ) published in Malesia raccolta 2 (1886.) Image (FIG 1) http://www.biodiversitylibrary.org/page/44197820#page/111/mode/1up



What little information I can find about the ecology of this species/form (?) will be found in my forthcoming book. 



I doubt very much if anyone herein can add to this.

Seram island http://en.wikipedia.org/wiki/Seram_Island


Buru island, http://www.worldwildlife.org/ecoregions/aa0104






Lesser Sunda islands. http://en.wikipedia.org/wiki/Lesser_Sunda_Islands


Flores island. http://en.wikipedia.org/wiki/Flores


Philidris cordata has been recorded on Flores Island and it is a species that prefers more open thus drier lowland savannah habitats.  http://www.antwiki.org/wiki/Philidris_cordata


Timor Island.  http://en.wikipedia.org/wiki/Timor



Edit. I posted in this format to make a point.

merci for all these infos .


what intrigued me precisely the profiles of these four ecoregions that were not identical for the same specie of Myrmecodia
AA00104; AA00118; AA00201, AA00204

http://www.worldwildlife.org/ecoregions/aa0204Timor and Wetar Islands Deciduous Forests.

I have no idea what AA00104 & AA00118 represent.

Buru island




Seram island





on your map the Wallace line runs between Bali and Lombok


these AA00201 ;AA00203; AA00204  are Tropical and Subtropical dry broadleaf forests


these AA00104 ; AA00118 are Tropical and Subtropical moist broadleaf forests


not the same ecology

The common denominator is that M. tuberosa "rumphii" reputedly occurs in lowland savannahs (widely spaced trees) at 20- 100 m. (66- 328 ft.) on Casuarina ( or Allocasuarina?) and Melaleuca tree species which indicates that there is insufficient rainfall at least year round for canopied forest to develop.  Casuarina (Allocasuarina?) and Melaleuca species are common hosts of myrmecophytes in Australia and New Guinea and melaleucas especially are frequently inundated ( that is their roots are) in their flood plain habitats during annual wet seasons.  Some Casuarina are now placed in Allocasuarina.
