ID of Utricularia species!:
Utricularia snaps from 1-4 are different species with floaters whereas Utricularia snaps from 5 to 7 are without floaters and smaller with yellow flowers!

Please check the following species

1-4 Utricularia aurea
4-7 utricularia exoleta

Would you please let me where you took these pictures from?

It had floaters followed with flowers which were above the surface of water. 1-4 Utricularia spp. Unfortunately these variety of plants aren’t existing anymore. Those photographs were taken four years back in one of the lakes of Bangalore!

I have never heard of Utricularia having floaters??
Is it possible that these are two different plants?

I think … was referring the Bladders as floaters.

No there are white things attached with the stem below flower twigs if you see.

But I think these floats are a part of many species of Utricularia, to make inflorescence to remain emerged.

Utricularia stellaris L.f. from Hooghly:

The book “Plant Groups” mentions two common floating herbs, Utricularia stellaris L. and Utricularia flexuosa Vahl. Failed to find much info on these two species. A post tells me that this plant might be the U. stellaris – https://groups.google.com/d/topic/indiantreepix/-g_Nhjwqf5k/discussion.

Species : Utricularia stellaris L.f. ?

Habit & Habitat : aquatic herb in a pond

Date : 16/10/12, 10.30 a.m.

Place : Garalgacha (Hooghly)

This looks like Ceratophyllum submersum to me. Please check.

Thank you for the probable ID.

I was confused yesterday when i tried to ID this pant. Internet gave me images of Utricularia aurea Lour. (syn. U. flexuosa Vahl.) that looked very similar – http://commons.wikimedia.org/wiki/Utricularia_aurea and http://www.kinmatsu.idv.tw/plant/Asteridae/Utricularia.aurea.jpg /

Now, Ceratophyllum submersum L. also looks similar.
I am not sure of which species i should go for.

Utricularia stellaris as per another thread.

Attaching the key of Utricularia in “Bengal Plants”.
