Lysimachia debilis ABJUL2019/01

[Ashwini Bhatia]

There is already some discussion on the nomenclature of this species. We seem to have decided on Lysimachia japonica ssp. japonica following the Flora of Pakistan and Saroj ji had pointed out earlier that the Plantlist and Plants of the World Online treat L. debilis as an accepted name. Also, Flora of China treats L. debilis as a separate species from L. japonica. I have followed the pdf here to look at the characteristic features of both these species. I am listing some differences for easy reference:

No. 60 in the pdf, L. japonica: leaves transparent glandular punctate, calyx 3-4mm enlarging to 7-8mm in fruit, corolla 5-8mm in diameter, style 2-3mm, flowering in March-April

No. 89 in the pdf, L. debilis: leaves (and corolla) reddish glandular punctate, calyx 7mm enlarging to 1cm in fruit and reddish glandular punctate, corolla 6x2=12mm in diameter, tube 2mm, style 4mm, flowering in June

Following these characters, our plants here and those posted by Saroj ji are almost certainly Lysimachia debilis. Flower size, red glands and flowering time are strong indicators. I am attaching some photos showing these and some other properties clearly.

The question, which resource to follow, however, remains. I am not sure which authority supersedes the other. I am inclined to follow L. debilis in the meantime.

Thank you.

All plants are photographed in June between 1750-2000m above Mcleodganj in Dharamshala, HP.

Dear Saroj ji,

I will be happy to help if I can. I am familiar with only five species found here: L. debilis, L. pyramidalis, L. chenopodioides, L. lobelioides, and L. prolifera and can look at your plants concerning these species. Could you please forward them again to me at this address?

Attaching the link to study all Lysimachia species here again for reference.

Regards,

Ashwini
