Plant for ID: Ernakulam, Kerala: 10 July 2021: 4 images.
Please help ID this plant that grows in the wild. It’s 40-60 cms tall with thin leaves.
Place: Kerala
Date: 10th July 2021
I am confused between Kyllinga elata and Kyllinga brevifolia.


I am not sure of the ID. Could it be Kyllinga elata, Kyllinga brevifolia or Kyllinga polyphylla?


It is Cyperus aromaticus (Redl.) Mattf. & Kük. (= Kyllinga polyphylla Willd. ex Kunth)
