Pollia subumbellata C.B.Clarke ??
What are the keys?
Sorry ! Not available sir.
To me yes, appears close to Pollia subumbellata C.B.Clarke, as suggested by …, as per comparative images at Pollia and keys in Flora of China and FoC illustration.
Five species are reported in BSI Flora of India Checklist, which appears to be available in NE India as per distribution herein.
Pollia hasskarlii ?
I think you may be right.
Looks close to Pollia hasskarlii as per GBIF specimens from India- one
Looks different from Pollia subumbellata as per GBIF specimens from India- one, two.
Also checked with descriptions in Flora of China.
May I request you to post high res. images to check further.
Yes, Pollia hasskarlii
