Report Hydnophytum sp. Surabi,Halmahera Is,Indonesia. in Hydnophytum - all species - with and without close Ant interactions (Rubiaceae) Posted April 9, 2014 Of course otherwise known as the Spice Islands. Bacan Island (Batjan in Dutch) sits relatively close to Halmahera Island (see maps) so perhaps there should not be much regional variation in hydnophyte species even though there is a probability that after seed has arrived over longer distances by birds, symbiotic ant species take over control of local distribution as found in the study by Maeyama et al. (2000.) http://en.wikipedia.org/wiki/File:Maluku_Islands_en.png http://en.wikipedia.org/wiki/Bacan_islands Maeyama T. Matsumoto T. 2000.
