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.

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.

http://www.worldwildlife.org/ecoregions/aa0201The Lesser Sundas Deciduous Forests on a string of volcanic islands across the Java Sea between Australia and Borneo.

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

I have no idea what AA00104 & AA00118 represent.

Buru island

 

http://www.worldwildlife.org/ecoregions/aa0104

 

Seram island

 

http://www.worldwildlife.org/ecoregions/aa0118

 

 

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.
