Dear efi users,today what I understand from key in FoIBasal lobe of wings (=
upper of lateral united petals) produced upwards anteriorly into decurved
lobule for I. edgeworthii.
Not as such for further many species.What I see is: upper part of upper of
lateral petals is short (narrow), lower part is much longer and spreading.There
is auricle, see https://www.inaturalist.org/observations/7651712 but not
particularly conspicuous and different than in Gurcharan ji's picture.Next
group of species is very diversified and I am unable to find something common
for them in terms of flower morphology...
This way understanding intentions of key authors is veeery difficult.Part
three tomorrow, I hope Wojciech

Sir, I have some clicks of this species. I'll check and report back.

Dear Gurcharan ji,what are you calling lobule?I see distinct structure in
place where upper lateral petal is connected with lower lateral petal.If yes,
this is some misinterpretation - this structure is auricle - see Fig. 1 in

Thanks dear Ashutosh Sharma ji and Wojciech Adamowski ji. I am also bringing
into loop Nidhan ji, Balkar ji and Anil Thakur ji who have good knowledge about
the flora of the region.Sorry but I won't stop at that. The main reason why
wrote three main posts "Sorting our Impatiens edgeworthii/scabrida/tricornis"
was the most important key character in BSI Flora of India, Vol 4 page 106
"basal lobe of wings produced upwards anteriorly into decurved lobule" which
separates I. edgeworthii from at least 50 next species in the key including I.
scabrida (I. tricornis not established then 1997, only emrged in 2016). These
lobules are very clearly seen in my images already on Flowers of India, our
database and fresh post yesterday. These are clearly absent in two species I.
scabrida and I. tricornis I uploaded yesterday. I must say these lobules are
very clearly seen in population uploaded by me from Nohradhar, and we can't
simply dismiss this as variation of tricornis. I don't say it is I.
edgeworthii, but can safely say that it keys out along with I. edgeworthii (in
key of BSI Flora of India). Who knows it may turn out to be a new species,
which our active researches can work on.A fresh trip to Nohradhar in June may
give us chance to locate and study this population in detail.

Respected Gurcharan Singh sir,
This is surely from Impatiens scabrida complex and will say Impatiens tricornis
for now.
See the plant is much hairy with pubescent lateral sepals also upper lobe of
lateral united petal is much wider and there is no streaked red color in throat
only rusty spots are present.
As this plant is photographed much earlier flowering in May at higher altitude
near 2000metres so this is likely some variation because it is flowering much
before monsoon rains and in cooler temperatures so plant growth also remain
stunted. I have seen such variations in some other Himalayan Balsams also...
Best regards Ashutosh Sharma

This is really interesting flower colour, lower sepal tube and hairiness
suggesting I. tricornis but two prominent lobules suggest I. edgeworthii, the
plant barely few cm tall is much more hispid than all my populations, Near
Nohradhar, Himachal Pradesh, alt 2000 m, May 25, 2015.
