Thanks to Arvind Singh for the PDF. The dimensions of the leaves given there for Mycetia mukerjiana are too big for the plants in question. According to World Checklist of Selected Plant Families (Kew), Mycetia longifolia is the only other species of this genus occurring in Bangladesh, that might look similar. Some other names classified in Mycetia, recently have been transferred from Myrioneuron and would have different inflorescences. The dimensions of the leaves given in the Flora of China treatment (http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=242423368 ) for Mycetia longifolia fit better. For comparison of size: The diameter of the berries would not be much more than 5 mm. So the leaves would not much broader than 5 cm.
