Pl. check comparative images at

Does not appear to be a Senecioneae member.
This appears more closer to images and details at Synotis cappa (Buch.-Ham. ex D.Don) C.Jeffrey & Y.L.Chen

Duhaldea cuspidata as per another thread: MS Dec,2018/04 Asteraceae for ID
This appears more closer to images and details at Synotis cappa (Buch.-Ham. ex D.Don) C.Jeffrey & Y.L.Chen
Duhaldea cuspidata.
Pl. see at Synotis cappa (Buch.-Ham. ex D.Don) C.Jeffrey & Y.L.Chen
I think it is not Duhaldea cuspidata because of Duhaldea cuspidata has stalked leaves, and the leaves in this plant are virtually stalkless. Synotis cappa appears close but if you look carefully, in Synotis cappa the ray florets are longer than the central disk of the flower-heads. In this plant the ray florets are much shorter than the central disk.
I think it is Duhaldea eupatorioides. The structure of the inflorescence and the leaves agree with the illustration attached here, and to the description in this paper.
I do not think so.

Pl. see detailed description as given below:

Duhaldea eupatorioides (Wall. ex DC.) Anderb. as per The genus Duhaldea (Asteraceae) in India (2020) | |
| Subshrubs or shrubby herbs, rhizomatous. Stems erect, to 150 cm tall, often flexuous, densely lanate or arachnoid-tomentose, ± glabrescent when old, simple or usually branching above in synflorescences, leafless in lower part at anthesis.
Leaves petiolate or sometimes subsessile; petiole to 10 mm, stout, densely tomentose, base often auriculate; blade broadly to narrowly obovate-oblanceolate or oblong-elliptic, 10-28 × 4-8 cm, papery, abaxially densely to sparsely fulvous pubescent on veins and densely to sparsely whitish tomentose, sometimes ± glabrescent, adaxially shortly densely to sparsely pubescent and sometimes thinly white arachnoid to subglabrous, pinnately veined, lateral veins 12-28, arcuate-ascending, base attenuate, margin finely to coarsely mucronulate-serrate, apically acuminate. Upper leaves and leaves of branches lanceolate or linear-lanceolate, gradually smaller. Involucres narrowly campanulate, 5-7 × 2-4 mm, calyculate; bracts of calyculus ca. 8, linear-lanceolate, 3-5 mm, apically acuminate; phyllaries 8-13, linear-lanceolate, ca. 1 mm wide, herbaceous, densely tomentose, margin narrowly scarious, apically obtuse to acute and puberulent. Fl. Oct-Jan. Forest margins, thickets, streamsides, meadows; 1500-2300 m. Guangxi, Sichuan, Xizang, Yunnan [Bhutan, NE India, Myanmar, Nepal, N Thailand]. |

Stout shrubs, 1–3 m tall. Stem pubescent, terete; branches brownish-purple. Leaves spirally arranged, rigid, leathery,shortly petioled; lamina elliptic-oblong or lanceolate-acuminate, 5–25 × 1.5–7.5 cm, coriaceous, irregularly toothed, cuneate or rounded at base, dark green above, scabrid, pale green below, pubescent, dense towards nerves, sometimes glandular, lateral nerves prominent, shorter, with much-reticulated nervation beneath.Corymbs polycephalous. Heads terminal or in upper axillary panicles; capitula crowned with short peduncles, 0.5–1.0 cm in diam. Involucral bracts 2–4 × 0.5–1.0 mm long, 4-seriate, lax, imbricate, lanceolate to linear-lanceolate, brownish, villous to velutinous, sometimes glandular at tip.
Flowering and fruiting from August to February. Habitat: Grows on rocky slopes, between 1700– 1800 m elevations. Distribution: Bhutan, China, India, Laos, Myanmar, Nepal, Pakistan, Thailand and Vietnam. |
But description in the publication says Ray florets a few, shortly radiate for Duhaldea eupatorioides. Also see the image of it in the publication, which is closer to our images in eFI site.
This is getting more confusing. The leaves of Duhaldea eupatorioides should be remotely toothed, as is seen in herbarium image at POWO. The leaves depicted in the drawing in that paper are correctly represented (attached here). However the leaves in the photograph of the plant, in the same paper, look very different. The leaf-margins of … plant do agree with the herbarium images of POWO and the drawing attached here. The flowers of … plant do look similar to the flowers in Chen’s clear image of Duhaldea eupatorioides that I posted earlier. For me that is a reasonable reason for considering it as Duhaldea eupatorioides.

Thank you.
These images on the iPlant link agree with my understanding of this species.
May I request you for post high res. images to see the phyllaries.
2 very high res. images.
Yes, I agree with the suggested id by …
Phyllaries seem to match as per these high res. image with those posted by …
