Habitat : Wild

Synotis triligulata (Buch.-Ham. ex D.Don) C.Jeffrey & Y.L.Chen

To me looks different from images at Synotis triligulata

What are the species reported from your area ?

Synotis cappa, S.lushaiensis, and S.triligulata are recorded in Mizoram

Synotis pentantha (Merr.) M.Tang, C.Ren & Q.E.Yang ??
Phytotaxa: In conclusion, Senecio pentanthus and Synotis triligulata are morphologically two distinct species. The former is a fairly widespread species occurring in Bhutan, China (Xizang, Yunnan), northeastern India, Myanmar, Nepal and northern Thailand whereas the latter is restrictedly distributed in Nepal. The following treatment, therefore, is necessary.
Synotis lushaensis (C.E.C.Fisch.) C.Jeffrey & Y.L.Chen looks more close?

Giving here the keys from Reinstatement of the Sino-Himalayan species Senecio pentanthus (Asteraceae, Senecioneae) MING TANG, CHEN REN & QIN-ER YANG – Phytotaxa 292 (3): 253–261 (2017):
