Dear efi users,sorry for delay in answer, but I am busy with several other
works at once.Impatiens scabrida/cristata/tricornis group is rather complicated
and still not fully explored.Please remember that I am living in place where
only one Impatiens is native and three other naturalized or invasive. What I
see are pictures of plants and my interpretation could be wrong. However, I
better understand what I see than what I read...
I will start with terminology to make things more clear.In most Impatiens
species flower has 2 or 4 lateral sepals, often green, but sometimes colorful,
one lower sepal and five petals: one upper or dorsal petal and two pairs of
connate lateral united petals. Lower sepal in most cases has spur. Lateral
united petals could have auricle, ofter darker in color than other parts of
petals. Upper petal could be flat ot cucullate; could have crest or horn.
Flora of India (FoI) in further texts) use following terms:wings = lateral
united petalslip = lower sepalupper lobe = upper lateral petallower lobe =
lower lateral petal
I don't know what is "lobular structure" in description of I. edgeworthii.I
will continue when time allows

You are best qualified to interpret it

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
