Sorry for unexpected break - I had some difficult days in my work.Now I would
like to explain my reluctance in giving names to plants known to me only from
pictures.There is a lot of confusion about this group and this confusion is
only partially solved by paper by Akiyama and Ohba.The same authors described
another taxon from this group - I. bajurensis with gigantic flowers:Akiyama S.,
Ohba H. 1993. Notes of Impatiens from west Nepal. J. Jap. Bot. 68(3):
156-158.Recently Czech colleagues found interesting form in Nepal, with rather
short lower sepal, but also rather short spur. This form has different
chromosome number.Also Rajib Gogoi in his book show 2 different forms with
rather short lower sepal: one yellow flowered and one almost white flowered. I
am not sure if his plants are true I. tricornuta and I. scabrida...
This way giving names to only superficially studied plants could be easily
error.
Best regards Wojciech

Thanks Garg ji,If second image 532 is accepted as I. scabrida, all others from
the same population should also be so. Shinobu Akiyama and Hideaki Ohba in
their 2016 where they suggested the shift of several specimens to I. tricornis,
mentioned characters of I. scabrida as "Lower sepal navicular or
infundibuliform,9–12 mm long, 5.5–8 mm deep (excluding the spur), tapering into
a long upwardly or downwardly curved spur; spur 17–25 mm in overall length".

Subject: [efloraofindia:343620] Sorting our I. edgeworthii/scabrida/tricornis
populations: I. scabrida from Tiger Fall Area Chakrata
To: efloraofindia <[email protected]>, Ashutosh Sharma
<[email protected]>, Wojciech Adamowski <[email protected]>
This population from Tiger Fall area of Chakrata seems to fit the description
in the Paper which led us here,and the absence of distinct lobule of I.
edgeworthii and "Lower sepal navicular or infundibuliform,9–12 mm long,
5.5–8 mm deep (excluding the spur), tapering into a long upwardly or downwardly
curved spur; spur 17–25 mm in overall length".
