Aponogeton appendiculatus (aponogetonaceae).

Kumarakom, Kerala, 2015 May

When we took boat ride in lake near Kumarakom i've collected this plant floating near shore 
Thanks to ... for identifying this beautiful plant.
A. appendiculatus is endemic to the coastal region of the Kerala and Tamil Nadu States of India.
It grows in brackish water streams of 1 − 1.5 m depth in the vicinity of the sea.
It can be distinguished from other Indian Aponogeton species by its brackish water habitat
