Polygala persicaraefolia, from Manipur.
Roots of almost all species of Polygala emit a characteristic smell (like Iodex balm) when crushed, due to presence of salicilic acid. The aroma vanishes within few seconds.

I think this property makes it an important medicinal plant

… reply on efi page at Polygala persicariifolia
“I find 4th post from Satara and the last post from Manipur looks different.”

I agree with …
This looks different from other images at Polygala persicariifolia

I find it closer to Polygala abyssinica as per comparative images at Polygala
However, I find its distribution in Himalayas upto Nepal only.

Polygala longifolia Poir. .  Polygala abyssinica have got no distribution !
