Here’s a new addition to efloraofindia site.
Mirabilis himalaica
Family – Nyctaginaceae
Synonyms – Oxybaphus himalaicus
This is a rather rare, native as well as Himalayan endemic sp. of genus Mirabilis earlier was treated under genus Oxybaphus which is now merged in Mirabilis.
It is notable that genus Mirabilis is having ca. 60 species that are distributed across temperate, tropical North America and South America and this is the only one sp. indigenous and endemic to Southern Asia/Himalayas (Spellenberg, 200)
Also M.himalaica is morphologically highly variable sp. and no. of stamens and pubescence of plant varies greatly in different habitats.
Photographed at Kalpa (Kinnaur) and Gushaini (Kullu), Himachal Pradesh
In September 2019-20

Thanks …,  I am also forwarding my captures of the same.. From same place in Ghusaini

This plant is now identified, thanks …, I was trying to fit it into Boerhavia sp. and in fact, an expert identified it to be Boerhavia diffusa, which I did not agree to..
Pending task is done by …

Check with Boerhavia repens, …

Thanks …, … this is only Mirabilis himalaica not any Boerhavia sp. for sure, even it has confused me earlier with Boerhavia but its not.

Taxonomic status and distribution of Mirabilis himalaica (Nyctaginaceae): Taxonomy and distribution of Mirabilis himalaica– Shu-Li Wang  Lang Li  Xiuqin Ci  Xiuqin Ci-  November 2018 Journal of Systematics and Evolution (Abstract- Mirabilis himalaica (Nyctaginaceae) is endemic to the Himalayas where it is used in traditional Tibetan folk medicine and is the only Old World representative of a large New World genus. The systematic position of M. himalaica and historical biogeography of Mirabilis and related genera was evaluated using two loci (nrITS, rps16), with divergence times estimated using ITS sequences. All 16 sampled provenances of M. himalaica formed a strongly supported terminal clade and at the sectional level formed a clade with sect. Quamoclidion sensu stricto, despite their morphology. Sect. Oxybaphoides and sect. Oxybaphus were not closely related to M. himalaica, suggesting their apparent morphological similarities are convergent. BEAST analysis and ancestral area reconstruction indicated that M. himalaica separated from related North American species during the late Miocene to early Pleistocene ∼5.22 Ma (95% HPD: 2.53–8.18). Both migration via the Quaternary Bering land bridge (Beringia) and long‐distance dispersal may have contributed to the present‐day disjunction between M. himalaica and the American species. These results agree with previous studies that suggest Oxybaphus should be merged into Mirabilis. However, although the infrageneric position of M. himalaica is still uncertain, it is not close to sect. Oxybaphus as has been suggested previously)
