It is common throughout its range in swamps, riverbanks, ditches, and moist places in tropical and subtropical forests. Although there is no detailed information about global population trend, it covers an extensive geographic range and seems to be common in a wide range of habitats. No major threats have been reported and the species is therefore listed as Least Concern. Conservation Actions: No conservation actions are in place.

Lasia spinosa (L.) Thwaites has very variable leaf-blades. Any probability?

---

The leaf in the middle is a Begonia. The early infructescence though, is from Lasia spinosa (Araceae) of which you can see parts of the lobed leaf blade on the right.
