Friends, thankfully we have now been able to resolve the controversy. Our plant is Matricaria discoidea DC. which is distinct from Matricaria matricarioides (Less.) Porter ex Britt., (treated as synonym of of Tanacetum bipinnatum subsp. bipinnatum) which is very different species as per POWO with depressed globose heads, phyllary margins brown and presence of ray florets as against oblong heads, phyllaries with white scarious margins and absence of ray florets. Tanacetum bipinnatum subsp. bipinnatum | Plants of the World Online | Kew Science <https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:77180698-1> Here is another good images of M. matricarioides Tanacetum bipinnatum - Изображение особи - Плантариум (plantarium.ru) <https://www.plantarium.ru/page/image/id/587499.html>
