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.

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.

    This is also D. chinensis
