Yes, this should be Artemisia nilagirica, which is quite a misidentified plant in India. The broad, toothed segments of the leaves are a clear signature. The more common plant with narrow, untoothed leaf segments is Artemisia dubia. In fact, all the plants listed on the eFI page for Artemisia nilagarica page should belong to Artemisia dubia. You can compare with the images of Artemisia dubia at POWO.

[J.M. Garg]

Thanks, Tabish ji, for the feedback.

But if you see, a lot of observations here (https://efloraofindia.com/2011/02/07/artemisia-nilagirica/) are from South India, where POWO does not give any distribution for A.dubia.

Yes Garg ji,

  I believe that lack of reporting from south India may be due to widespread misidentification. If you closely follow the description & the few correct herbaria, you can see the difference. An example of correct representation of Artemisia nilagirica, will be the images by Sushant More on GBIF and iNaturalist:

   https://www.gbif.org/occurrence/3017958685

   https://www.inaturalist.org/observations/67413716

In the description of Artemisia nilagirica on FOC, the leaves are supposed to have "...segments 1-3 pairs, ovate or oblong-ovate, usually 1- or 2-serrate, acuminate apically." The narrow, almost linear segments, of the leaves, which are untoothed, of other plants do not fit this description.

  This, coupled with the images of Artemisia dubia on POWO, in my opinion, makes a strong case for this view.

Thanks, Tabish ji.

If you check in GBIF, both types of specimens are available.

Keys between the two may help.

Garg ji,

   I did notice that there are a few other type of specimens too for Artemisia nilagirica at GBIF. However, I believe that those may be misidentifications.
