Distribution
Aru Is present, Asia-Tropical: Jawa (Jawa present ‒ present); New Guinea present; Philippines (Philippines present), Bogor present, Luzon present, Maikoor I present, Mindanao present, North Sumatra present, S. Moluccas present, South America absent, Toba Lake present, inundated rice-fields near Bandung and Garut present, worldwide present
Worldwide, but curiously absent from South America, extremely scarce in Malesia: North Sumatra (Toba Lake, not collected, cf. STEEN. 1932), Philippines (Luzon, Mindanao), S. Moluccas (Aru Is.: Maikoor I. leg. BECCARI, 26-6-73), and New Guinea.
For Java recorded from Bogor by MIQUEL (1855, l.c.) and again by MASSART () from inundated rice-fields near Bandung and Garut. No other botanists or collectors have ever found it in Java, so that we may safely assume that these two records rest on errors.
