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 conclusionSenecio 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):
Key to Synotis pentantha and its similar species
1. Capitula conspicuously radiate ..........2
–   Capitula minutely radiate ..............3
2.   Leaves with prominent, distinct veins beneath ...........Syn. lushaensis
–   Leaves with obscure veins beneath .............Syn. vagans
3.   Corymbs dense, glomeruliform, 2–4 cm long ........4
–   Corymbs more lax, spreading, 4.5–10 cm long ....5
4.   Leaves coarsely and deeply serrate, auriculate at the base ..............Syn. rhabdos
–   Leaves finely and shallowly serrate, exauriculate ...............Syn. glomerata
5.   Leaves broadly ovate, ovate-lanceolate or elliptic ...............6
–   Leaves narrowly lanceolate or narrowly oblong .................9
6.   Phyllaries 5; disc florets 2 or 3 .........Syn. penantha (Synotis pentantha is widely distributed in Bhutan, China (Xizang, Yunnan), northeastern India, Myanmar, Nepal, and northern Thailand (Fig. 5). It grows in open forests, on forest margins, or among scrub at elevations between 1100–2400 m above sea level)
–   Phyllaries 7–10; disc florets 5–10 ....................7
7.   Capitula 3.5–4 × 1.5 mm; phyllaries 6–8 mm long; marginal florets ligulate, conspicuous .........S. triligulata
–   Capitula 4 × 2.7 mm; phyllaries ca. 4 mm long; marginal florets minute, filiform .........8    
8.   Stems, veins on abaxial surface of leaves and peduncles all densely glandular fulvous-pubescent ...........Syn. saluenensis
–   Stems and leaves glabrous; peduncles pubescent .............Syn. simonsii
9.   Leaves auriculate at the base ...................Syn. auriculata
–   Leaves exauriculate ................Syn. baoshanensis

Here are the keys from Flora of China:
40 (39)Leaves pubescent or thinly tomentose; ray lamina ca. 3.5 mm. 23 S. cappa
+Leaves glabrous; ray lamina ca. 6 mm. 3 S. longipes
41 (39)Corymbs dense, glomeruliform, 2-4 cm. 33 S. glomerata
+Corymbs more lax, spreading, 4.5-10 cm (42)
42 (41)Capitula ca. 4 × 2.7 mm; phyllaries 8. 36 S. saluenensis
+Capitula 3.5-4 × ca. 1.5 mm; phyllaries 4 or 5 (43)
43 (42)Leaves ovate or elliptic, basally not auriculate; ray florets 3 or 4. 34 S. triligulata
+Leaves narrowly elliptic or narrowly oblong-elliptic, basally auriculate; ray florets 2. 35 S. auriculata

So pl. post the high resolution images to check all these aspects.
4 images- 6 to 7 mb each.
I will go for Synotis triligulata


Distribution Pattern of Synotis (C.B. Clake) C. Jeffrey & Y.L. Chen (Senecioneae : Asteraceae) in Nepal Sudha Joshi (Shrestha)- Himalaya Pleione 11(2): 177 - 186. 2017. (Abstract- The distribution pattern of ten species of Synotis (C.B. Clarke) C. Jeffrey & Y.L. Chen in phytogeographical regions and bio-climatic zones in Nepal along with the species richness was studied. Central Nepal houses the highest number of species, followed by the east Nepal. West Nepal has the least number of species. Within the bio-climatic zones, the highest numbers of species are present in the temperate zone, followed by subalpine zone and then subtropical zone. Alpine zone houses only three species of Synotis. The species richness is peaked in the central Nepal and at the elevation of 2100 – 2200 m and 2400 – 2600 m.)
