Images of Dicliptera chinensis in FOI appears close to Dicliptera riparia Nees (syn. Dicliptera roxburghiana var. riparia (Nees) Benoist) as mentioned in the Checklist of Nepal as per GBIF specimens.
Catalogue of Life gives its distribution as India (Himalayas, Plains of E-, N- & NE-India, Upper Gangetic Plains), Myanmar [Burma] (Bago, Taninthayi), Thailand, Nepal.
For Dicliptera chinensis (L.) Juss. (syn. Dicliptera roxburghiana Nees), Catalogue of life (China (Fujian, Guangdong, Hainan, Guangxi, Hongkong, Macao, Yunnan, Guizhou, Sichuan), Taiwan, Indochina, Pakistan (Baluchistan, Quetta, Waziristan, Kurram, N.W.Frontier Prov., Dir, Swat, Pakistani Punjab, Salt Range, Rawalpindi, Hazara), Ryukyu Isl., Hawaii (I) (Kauai (I), Oahu (I), Molokai (I))) does not mention its distribution in India. POWO (Afghanistan, Assam, Bangladesh, Cambodia, China South-Central, China Southeast, Hainan, India, Laos, Myanmar, Nansei-shoto, Pakistan, Taiwan, Thailand, Vietnam) also does not give its distribution in the Himalayas.
So I think our Himalyan plants should be Dicliptera riparia Nees (syn. Dicliptera roxburghiana var. riparia (Nees) Benoist)

According to POWO, Dicliptera riparia is found from Nepal eastwards to China. Flowers at FOI were found in Nainital. So, it is highly unlikely they belong to Dicliptera riparia.

Hi, Tabish ji,
For Dicliptera chinensis (L.) Juss. (syn. Dicliptera roxburghiana Nees), POWO does not give its distribution in the Himalayas.
So it is highly that it is Dicliptera riparia Nees (syn. Dicliptera roxburghiana var. riparia (Nees) Benoist) as per Catalogue of Life (Himalayas, Plains of E-, N- & NE-India, Upper Gangetic Plains), Myanmar [Burma] (Bago, Taninthayi), Thailand, Nepal.
Also our observations match with GBIF specimens and are the same as those from Nepal.

There are no other closer species found in the Himalayas.

Also references in POWO seem quite old.
Karthikeyan et al. (2009), I think did the revision/ checklist in 2009 as per detail at Dicliptera: FLOWERING PLANTS OF INDIA, DICOTYLEDONS, Vol-I (Acanthaceae-Avicenniaceae) authored by S.Karthikeyan, M.Sanjappa and S.Moorthy and published by Botanical Survey of India, Kolkata in 2009

"POWO does not give its distribution in the Himalayas. "
That may be just because it is found only in the Himalayan foothills, and not the Himalayas. According to Flora of Morni Hills, it is found in Morni hills. However, Dicliptera chinensis is supposed to have a very wide distribution, from E. Afghanistan to SE Asia.

Well, I don't know about others, but Balkrishna, A. (2018). Flora of Morni Hills (Research & Possibilities): 1-581.is reasonably new.

My feeling is that for some taxon it has given some references and for others it has not. It is also not based on WCSP, as it is not available over there. The Plant List is based on WCSP (under review). It does not show any reference of Karthikeyan et al. (2009), which is the main work on this genus in India.

POWO shows distribution of species on Maps, which can be very misleading for India.
Just to give an example, Dicliptera nasikensis is distributed in Nasik district of Maharashtra only as per Catalogue of Life and Flora of Peninsular India.
Just to give an example, Dicliptera nasikensis is distributed in Nasik district of Maharashtra only as per Catalogue of Life and Flora of Peninsular India.
However, if you see it in POWO, its map will show as if it is distributed all over India except for Assam and Himalayas. On clicking Full Distribution Listing under it, it says Native to India.
As per my experience with it, it has divided India into four regions- India, Assam, West Himalaya and East Himalaya.
So it is found in Nasik or Maharashtra only, it will show the area as shown at POWO and similarly for other three regions.
So beware- don't think it is distributed all over India and be careful.

Well, now Dicliptera chinensis, with a wide distribution, is completely missing from eFI. More thinking and research may be required in this.

Hi, Tabish ji,
All of our observations are from the Himalayas, where Dicliptera riparia Nees (syn. Dicliptera roxburghiana var. riparia (Nees) Benoist) is found and not Dicliptera chinensis (L.) Juss. (syn. Dicliptera roxburghiana Nees).
Nobody has posted anything similar to Dicliptera chinensis (L.) Juss. (syn. Dicliptera roxburghiana Nees) from other areas.

Even the page of Dicliptera roxburghiana in Flora of Peninsular India is blank.
Neither Flora of Pakistan nor Checklist of Nepal mentions it.
I could not find many regional references where it is mentioned at Dicliptera
Catalogue of Life also does not give its distribution in India (China (Fujian, Guangdong, Hainan, Guangxi, Hongkong, Macao, Yunnan, Guizhou, Sichuan), Taiwan, Indochina, Pakistan (Baluchistan, Quetta, Waziristan, Kurram, N.W.Frontier Prov., Dir, Swat, Pakistani Punjab, Salt Range, Rawalpindi, Hazara), Ryukyu Isl., Hawaii (I) (Kauai (I), Oahu (I), Molokai (I))
So it may be rare in India or some other variety other than type variety of Dicliptera roxburghiana Nees may be reported.

This is D.chinensis only as per details at Dicliptera roxburghiana and Dicliptera roxburghiana var. bupleuroides

Thanks Garg ji for accepting D. chinensis, which for me is a very distinct species from D. bupleuroides
