Suprisingly, Phragmites australis is seen both in tropical and temperate areas and always associated with a wetland. The differences between the tropical and temperate forms need to be worked out in detail. However, Phragmites karka is a different species altogether and not seen in wetlands or lakes, but usually found on hill slopes in middle himalayas. All Phragmites in India are being treated as P.karka by many authors, though the hill form is different from the wetland species whether tropical or temperate. I think this needs further investigation.
