Epilobium sp. for id from UP -2011: This one I think is an Epilobium sp. Was shot from Shukartaal, in U.P. in June 2011. The flower size of this herb was about 1 cm across, the fruit nearly 2-3 cm in length. Hope to find the exact id.


How about Ludwigia perennis???


Yes, the fruits of Ludwigia are seen in pictures (1), (7) & (8).


I guess Ludwigia plants occur near water streams etc. Was the habitat similar here?
Any way nice pictures indeed.


Thanks for liking. This plant was shot from the lawn of a community park, but it was in along the bank of River Ganga. Hope to find exact id soon..


It is not epilobium may be ludwigia sp.


Does not seem to match with any species of Ludwigia as per comparative images and details herein.


I think close to Oenothera affinis as per
GBIF specimen one and two

Thank you very much … for floating this post again..
This never came to my mind being a very old post and, incidently, the original image collection of this tour somehow totally escaped my attention..
I hope the correct identification has been ultimately established by your efforts…

Onagraceae member for I’d; Oenothera sp. ? — YS_Mar21/01: 3 high resolution images.

This is an interesting member of family Onagraceae, recorded from Rewari, Haryana. It could be any Oenothra sp. Please help to identify it.
Date of Photo – Feb., 2021

Place of Photo – Rewari, Haryana


I think Oenothera affinis Cambess. as per images and details herein.


Thanks a lot respected …, for your response.

I have visited across the links on the page provided by you and it does not seem a satisfactory match. Flower size is very smaller in my posted plant in comparison to that in the photos and description in the links provided. Although I’m not an expert, but according to me, flowers are not observed to vary in size to this extent, leaves usually vary in size. So, we have to research more about this plant and expert’s advice is required.

To me, the comparative size of flowers, leaves and fruit matches well with the images at the efi site link. I think no other species as listed in various floras at Oenothera, comes close.
