This is most probably Circaea alpina (Onagraceae)


efi page on Circaea alpina


It is Circaea alpina L. subsp. imaicola (Asch. & Magnus) Kitam. (Onagraceae). A common temperate and alpine herb throughout Himalaya.


I think yes.

This small herbaceous plant reminded me first of a Lindernia but the flowers born on tall stems ruled that possibility out. Please help identify it.

May have to rethink about this and second one (young flowering) uploaded by … Notched petals appear strange. Please upload if you can locate some fruits.


I am sorry for not having any fruit pics…infact I could not see any..


Perhaps seeing it after 40 years, but if I am not wrong this should be Circaea alpina.


Perhaps you have resolved the identity…this looks like Circaea alpina…never heard about this…thanks a lot sir…


Wonderful identification …! Experience of a seasoned botanist shows!

This very small herb was shot during our recent tour to the Chakrata area, earlier I had recorded this during Valley of Flowers Trip..
Hope I am right in matching this with Circaea alpina L. which was identified by …


Flower size looks larger, or is it the macro?


Sir, if it looks bigger, may be due to Macro.. the flower size was similar to the one seen during VOF Trek…


Circaea alpina.

A reply from another thread:
“May have to rethink about this and second one (young flowering) uploaded by … Notched petals appear strange. Please upload if you can locate some fruits.”

Could this be Circaea alpina subsp. micrantha.

Thought about this after identifying another plant as Circaea alpina, but never seen such condensed inflorescence and congested leaves in that plant.
