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.

Thanks, Tabish ji,
I do not think so.

Pl. see

Pl. see detailed description as given below:

Upper leaves and leaves of branches lanceolate or linear-lanceolate, gradually smaller.  Capitula radiate, usually numerous, arranged in terminal and axillary usually 10-20-headed dense compound corymbs or thyrses; peduncles 5-10 mm, densely tomentose, with a few linear or linear-subulate bracts.

Disk florets 11-17; corolla yellow, ca. 5 mm, with ca. 1.5 mm tube and funnelform limb; lobes ovate-oblong, ca. 1.5 mm, apically acute. Anthers ca. 2.5 mm; anther tails slightly exceeding antheropodia; appendages ovate-oblong; antheropodia rather slender, basally slightly dilated. Style branches ca. 1 mm, fringed with short papillae, terminal tuft not evident. Achenes ca. 2 mm, glabrous. Pappus white, ca. 5 mm. Fl. Oct-Jan. Forest margins, thickets, streamsides, meadows; 1500-2300 m. Guangxi, Sichuan, Xizang, Yunnan [Bhutan, NE India, Myanmar, Nepal, N Thailand].

Thank you Garg ji for the detailed comparison.

   But I do not think the images at the eFI link correctly represent the species Duhaldea eupatorioides. The flowers seem to have almost no ray florets. I am attaching an image of Duhaldea eupatorioides from this paper. Another paper summarizes Duhaldea eupatorioides as follows:

 Notes: This species is similar to D. cuspidata, but differs in much stouter habit, shorter and stouter petioles, more rigid leaves with much reticulated nervation beneath and narrower ligules.

Comparing with the images of Duhaldea cuspida, I feel Sawmliana's images fit the description of Duhaldea eupatorioides reasonably well.

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.

[Tabish]

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 Sawmliana's plant do agree with the herbarium images of POWO and the drawing attached here. The flowers of Sawmliana's 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 Saroj! These images on the iPlant link agree with my understanding of this species.
