This rare Utricularia too was seen at Shahpur, Mah. on 28 March ’10. Is this lutea species?
This is U. exoleta a semi aquatic plant found on rocky fresh water streams.
I will vote for … this plant is indeed Utricularia exoleta R. Br.
ID of Utricularia species! : Attachments (7). 15 posts by 6 authors.
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!
is the order with flowers and with floaters just reverse than written
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.
oops yes I could see it now. Thank you for point it out.
But I think these floats are a part of many species of Utricularia, to make inflorescence to remain emerged.
Thanks for the information sir…
Thank you sir for the clarification.
