Attaching here a small sized pic of another aquatic plant that i thought was the same as this one (with the monkey-puzzle-butterfly). but this attached pic doesn’t tally with yours shots.


This plant is clearly distinct from the one in your previous post.


Yes Sir, it is another species, your document tells me so. But, as i said earlier, i thought both were same. However, i will post a seperate document seeking ID of this one too.


the uploaded herb photo is of Alternanthera philoxeroides (Mart.) Griseb. from Amaranthaceae family.


I think … got it correct FOI

AMARANTHACEAE-CHENOPODIACEAE week: Alternanthera philoxeroides:  Alternantheragenus is represented by 11 naturally occurring species in India. Most of them are weedy in nature. Enclosing here pics of A.philoxeroides which is a common weed along water channels here in Pantnagar (Uttarakhand).

The young shoots are said to be edible. It is also known to accumulate heavy metals.


Very nice pictures with great details!

Chenopodiaceae and Amaranthaceae Week: NS 007: Alternanthera philoxeroides from Kaithal: This aquatic weed was shot from a village pond in 2012… Alternanthera philoxeroides (Mart.) Griseb. the alligator weed


Yes … Very good photographs


Thanks for sharing these beautiful photographs. This species is one of the most predominant invasive plants in the world. It is available in the markets of West Bengal as leafy vegetables and locally known as “Chhenchi shak” and has really good taste.


yes. a bad weed. some eat it, but at their own peril
it supposedly concentrates heavy metals in shaloow water ways or canals…
only a very large BW beetle eats it… in nature…. could be a famine food…
have not seen it in neighbourhood markets in south 24 paraganas’cities,
but as … says it must be available in local areas where it grows….  Thanks … for the name


This is a very bad weed… must be eradicated where found…
please read pg 12 of this pdf from Australia dept of BIOSECURITY
I was distrubed by the numbers in reduction in crop production due to this weed in china… pg 12 of pdf or sec1:10 in its own parlance….
we dont have a dept of BIOSECURITY do we?


its other name is ALLIGATOR WEED. WONDER WHY?


I have no knowedge of this being used as a food here in our state …only considered a weed… usually cannot compete with Eichhornia which overpowers this….. Alligator may be due to its dominating nature….


It can invade mid Himalayan hills along water channels. I have recorded it from 1400m altitude near Naini Tal, Uttarakhand.
