Lysimachia alternifolia from Tiger fall area Chakrata:
Lysimachia alternifolia Wall., Roxb. Fl. Ind., ed. Carey & Wall. ii. 26 (1824)
The plant at first look reminds you of Anagallis with similar long axillary pedicels and shape of fruits surrounded by similar calyx lobes, but alternate leaves and yellow flowers lead to look you for some thing closer, and it landed me to Lysimachia alternifolia very distinct from other species in alternate leaves, long slender pedicels and yellow flowers.

Lysimachia alternifolia..

Nice photographs of Lysimachia alternifolia,


Yes … we clicked it together, I was excited to see this plant resembling Anagallis but with yellow flowers, later identified as Lysimachia.


Interesting similarity with Anagallis.


Yes …, I was considering this Anagallis only, till … identified this as Lysimachia

This herb was shot from Kalimpong and Pelling in Sikkim in May 2014, I hope this is a Lysimachia sp.
can this be L. debilis ?? Please suggest id..


For me it is very close to Lysimachia evalvis.


Very similar to your another Lusimachia suggested by you as L. foenum-graecum


Thanks a lot … for inputs and appreciation…
I hope a final verdict regarding id will be obtained soon..


efi page on Lysimachia foenum-graecum. However, no distribution in India is shown for this in FOC as per link: Lysimachia foenum-graecum
FOC page on Lysimachia evalvis

I think more closer to images at Lysimachia tetragona (syn. Lysimachia alternifolia Wall.) rather than those at Lysimachia evalvis as per
However, looks slightly different w.r.t. the relative size of the pedicels vis-à-vis the leaf size, sepals being longer than the petals ect. May be some closely related species.

Please permit me to upload some of my pending pics of the fortnight, due to network issues I could not complete my uploads till 14th June. This one was also shot from Pelling, may be similar to one earlier uploaded and tentatively identified as Lysimachia evalvis by … this mainly differs in having violet colour of stem and leaves…


Ludwigia sp. probably


I do not think it could be Ludwigia sp.
I have same type post. … could you please check the link below once.
Link


Yes, … Your plant appears to be same.

And it appears to be close to Plant illustration but description in Flora of China appears to be contradictory.
Description better matches with Biodiversity of Bhutan
Pl. decide.

Yes, I guess not matching !

Pl. check species available at /species/m—z/po/primulaceae/lysimachia 


Someone suggested it could be L. alternifoila and coloration due to pigments looking for light.
Your opinion please.

Yes …! Description seems matching but cannot confirm.
Do we have any member having more knowledge in this sp.?

Sikkim is the smallest state with more than 5000 species of flowering plants. I know less than ten percent of that during my tenure there. The genus is confirmed. The species I do not know.


Yes it is Lysimachia alternifolia
