Dear all,
for my further studies on ecology of Coleoptera I am looking for assistance with naming plant species / genus from New Guinea (see photos). Exact locality data and other information are provided here: http://www.inaturalist.org/observations/anthicus
These plants are growing on muddy banks of rivers from Raja Ampat (Raja Ampat - Misool.jpg) in the W to Merauke (Merauke1 &2.jpeg) in the S of New Guinea (s.l.) and are abundant. I consider these are Alismataceae Gen. sp.
