Conservation
Data Deficient (DD), but there being only three collections suggests vulnerability.
Distribution
Sulawesi.
Ecology
Lakeside forest, sometimes growing in the water; 300 – 400 m.
Note
The skimpy description provided by Knuth fits this taxon in all important respects but one. Knuth states, inter alia: cuneate-oblong to obovate glabrous leaves congested towards the tips of 5 mm thick twigs, petioles 1.5 – 2 cm long; racemes 3 – 6-flowered; pedicels 3 cm long; flowers fairly large, white; sepals 13 mm long, glabrous outside, sericeous on the margins and inside; petals longer than the sepals to 15 mm; stamens 10 mm long, filaments 2 – 3 mm, awns 3 mm — all these details fit and only the reference to sepals glabrous outside (the recent specimens have sepals finely adpressed-silky, less than the inside) seems to argue against the identification, while Knuth's mention of petals glabrous in the description (the new material has petals somewhat adpressed-pilose in the lower half outside, with rather more indumentum on the claw inside) is contradicted by his subsequent note ""Affinis E. obtuso Bl. a quo distinguiturpetalisextussparsimpilosis"". I have left a full description, based on the three collections given above, in the Herbarium at Kew.

Note that the typical subspecies also occurs on Sulawesi, albeit on the rather distant southwest peninsula.

It is unfortunate that either details of the locality and habitat were not given by the collector on the holotype (now destroyed) or that Knuth did not publish them. I have not seen copies of Heinrich's Der Vogel Schnarch of 1932 and Celebes, SeltsameJagddurchseltsames Land (1943) but Dr van Balgooy of the Rijksherbarium, Leiden, has kindly investigated maps at his disposal, and has found a small village called Lalolei just east of Kolaka, and apparently at the edge of a swamp. Heinrich was apparently in the Kolaka area at the time (Steenis-Kruseman1950: 223 – 4). Other species collected by van Balgooy, Musser and de Vogel in central Sulawesi have subsequently been found in the southeast slopes of Mt Watuwila (part of the Mengkoka range North of Kolaka) — Elaeocarpusbalgooyi Coode and E. erdinii Coode (2001) and E. musseri Coode (1995). It therefore seems reasonable to suggest that the distinctive lakeside taxon found by van Balgooy and de Vogel in lakeland area of central Sulawesi is the same as what Knuth described as E. heinrichii.

On the island of Simuelue, off the NW coast of Sumatra, is a variant sufficiently distinct to describe as a new species, Elaeocarpusachmadii; it resembles E. macrocerus in many respects but has smaller petals with much shorter apical teeth. Unfortunately, the collections lack precise locality and merely state ‘swamp forest’. E. macrocerus is also found on Simuelue.
