Dicliptera bupleuroides Nees (syn: Dicliptera roxburghina auct. (non Nees which is synonym of D. chinensis)) from Mandi H. P., common in the Himalayas at lower altitudes ascending to 2200 m, not to be confused with Peristrophe roxburghiana (Roem. et Schult.) Bremek (syn: P. tinctoria (Roxb.) Nees) which is a cultivated species with much larger flowers (nearly 3 cm as against 1.5-2 cm in D. bupleuroides) and few flowers generally towards top of branches.

Thanks Sir for indicating the difference and also I was unaware of the complex nomenclatural history of this plant.

Dear Gurcharn ji,
This species has been troubling for a long time, and it seems the
troubles are still not over. Comparing your pictures with the
illustration at Flora of Pakistan:
http://www.efloras.org/object_page.aspx?object_id=86909&flora_id=5
One petal of the flower has three teeth, and the other is notched. In
your picture, one petal is 3-toothed, but the other is clearly not
notched. Also the leaves in the illustration are long-stalked, whereas
those in your plant appear to be short-stalked or stalkless.
With one petal 3-toothed, and the other one pointed, your flower
reminds me of Peristrophe, however I will let that speculation be at
the moment.

to Tabish, efloraofindia
Thanks Tabish ji for your critical observation:
Here is description from Flora of British India, Page 554 for Dicliptera
"upper lip entire or emarginate", "lower 3-toothed recurved"
As far as leaves are concerned, petiole length varies from 4 mm to 25 mm. It is usual to find lower leaves petioled and upper sessile. The photographs are from the upper region where flower-clusters are present. You may check up illustration on page 377 of "Flora Simlensis" The key features between the genera are the fruit dehiscence (which of course we are not seeing in this case) and inflorescence which in Peristrophe appears paniculate (as you can clearly see in Perstrophe paniculata and links I have provided for P. roxburghiana (syn: P. tinctotoria). I fear the two photographs appearing at FOI belong to two different species, second possibly to Dicliptera bupleuroides, and first definitely not P. roxburghiana). P. roxburghiana is a cultivated species and not growing wild in Himalayas. You may observe my links carefully. I am uploading one more photograph to show faint notch. I am providing more links for P. roxburghiana

Thanks Gurcharan ji, for the clarifications. I have always been
uncertain about my identification of Peristrophe roxburghii at FOI -
will give a revised look. Thanks particularly for the link of the
illustration of Peristrophe roxburghiana - this is something I wanted
badly. I was not too worried about Peristrophe roxburghiana being a
cultivated plant because we found it in Nainital, where there are lot
of flora planted by the British, and garden escapes are common.
Meanwhile, does any of your pictures of Dicliptera bupleuroides show
the sepals - I believe they are supposed to be linear-lanceshaped.

Dicliptera chinensis as per images and details herein. Looks different from Dicliptera bupleuroides as per images and details herein.
Differences between the two species are better appreciated as per FoC illustration and FoP illustration

On further examination and discussions at thread: Dicliptera bupleuroides Nees (accepted name) ??? , I feel it should be Dicliptera riparia Nees (syn: Dicliptera roxburghiana var. riparia (Nees) Benoist) as per distribution, specimens and references herein.

Dicliptera riparia has distribution only in Eastern Himalayas, not in Western Himalayas.
I should be D. chinensis (L.) Juss. (Syn: D. roxburghiana Nees) which has distribution in most of India including W. Himalayas according to POWO

Thanks, Singh ji,
No distribution in W. Himalayas according to POWO.

Whole of India is marked. If it is in Pakistan, Western Himalayas is automatically covered. POWO treats it as accepted name and I want we should follow it
Looking at corolla size it safely fits into D. bupleuroides
All three similar species are listed in FBI (under names D. riparia, D. roxburghiana and D. roxburghiana var. bupleuroides): Here is comparison of accepted names
D. riparia Nees is distributed in Pegu and Tenassarim (Myanmar),FBI according to Flora China Nepal, Myanmar to Yunan: Lesves ovate, obtuse often emarginate bracts, bracteoles 6 mm, linear.
D. chinensis (L.) Juss. (Syn: D. roxburghiana Nees): Leaves ovate-elliptic, base cuneate to attenuate, decurrent on petiole, outer bracteoles 5-13 mm x 3-8 mm , less than twice as long as broad, corolla 10-12 mm long; Throughout India
D. bupleuroides Nees (Syn: D. roxburghiana var. bupleuroides (Nees) Clarke): leaves ovate, base cuneate; outer bracteoles 5-7 mm long, more than twice as long as broad; corolla 5 mm long.; Throughout India
When looking for specimens from Western Himalayas we have to be vigilant about size of corolla and relative length breadth ratio of outer bracteoles.
Looking at corolla size it safely fits into D. bupleuroides

Western Himalaya is neither marked in the map nor stated in the text in POWO.
It is specifically mentioned in POWO, whenever there is a distribution.
POWO always mentions the following (for India and Nepal) in its text:
Western Himalaya,
Western Himalaya,
Eastern Himalaya,
Assam,
Nepal,
India (other than above)
For other aspects, I will again have a re-look.

When whole India is marked, how can you exclude Western Himalayas. FBI says throughout India
from 1-6000 ft, Himalayas from Kashmir to Assam; Collett records from Simla.
