Common in forest areas in Kashmir and along streams.


Spectacular. Thanks … for another interesting upload.


Recently (2001) found in Germany. Described there as robust plant upto 180 cm! What is more puzzling intermingled are growing plants with yellow, white and pale violet flowers…
Till now I have seen only photographs, but if I only have chance, I will go this mere 1000 km to see it personally.

Anybody seen plants with this shape of lateral petals and pale violet color somewhere in Himalayas, Karakorum, etc.?


I am very glad to see that Indian botanists are becoming aware of Impatiens edgeworthii as a problem.

Last year in Central Germany about 1 million of this species did grow in Central Germany, most of them in the Leinawald (Leina forest) near Altenburg.

From the beginning I was aware the descriptions of this species in the Flora of Pakistan and elsewhere did not agree with what we are seeing in Germany.

I did publish on the ecology

http://www.v-weiss.de/Impatiens-edgeworthii.pdf

or

http://botanischer-verein-sachsen-anhalt.de/wp-content/uploads/2016/10/Flo-Kart_2013_015-029_Weiss.pdf

and a  monograph on Impatiens species in Central Europe, see amazon

    

I did upload a number of additional pictures of Impatiens edgeworthii from Germany to my twitter and facebook accounts. 

From my point of view, to solve the riddle of this and related species finally, it would be necessary to make controlled experiments and crossings with seed from Kashmir and Germany. However, until now did find any partners for cooperation in India or Pakistan. 


why is this old case coming up now?

i dont see anything new!!!!


why is this old case coming up now? Quite right, because there is anything new since 2013.
Despite the fact, that the Impatiens edgeworthii growing in Germany seems not to be identical with the I. edgeworthii of India.
What is needed, are not only nice pictures and discussions, but cooperation across borders, crossing experiments and molecular genetics.


cooperation across borders on genetic materials is a sensitive issue among governments, at least that’s how i understand. one must contact proper authorities thru proper channels. i don’t think individual worker can say yea or nay


.


Let me thank both …,   for giving me the hope that we may have I. scabrida occurring in our region and … for keeping the thread alive.

Let me first point out basic difference which separates I. edgeworthii from nearly 50 next species in BSI Flora of India (luckily I had purchased few years back) i.ei “Basal lobe of wings produced upwards anteriorly into decurved lobules” and most parts of plant including capsule grabrous. This is clearly seen in my Kashmir specimens attached here. This Flora published in 1997 though totally ignorant about the name I. tricornis (not even in synonyms) does correctly record navicular lower sepal and other features of hairy stems, leaves and fruits, that should help us separate the rest of specimens. I will be discussing the populations separately.
Please correct me if I am wrong.
This plant was photographed from Baramulla Kashmir, alt. approx. 1600 m on June 24, 2010.

Impatiens edgeworthii for sure. Look the same like material from Germany https://www.korina.info/arten/buntes-springkraut/


/wp-content/uploads/2020/10/I.%20edgeworthii%20-1-.JPG

Let me plunge into the discussion, with entries from Kullu, which I believe to represent Impatiens edgeworthii.. (3 images attached here)

I do had submitted both I. scabrida
and also I. scabrida/tricornis 
Let us see what the experts have to say..

Impatiens edgeworthii


I also think this one is yellow-flowered form of I. edgeworthii

Impatiens Sp. for ID…en-route Rolla- GHNP- PKA36 :  3 posts by 2 authors. Attachments (5).

This Impatiens sp. was seen en-route Rolla at GHNP at an altitude of approx 1700m.
Could this be Impatiens edgeworthii ??


Yes this is Impatiens edgeworthii – please notice rather narrow upper lateral petals, spreading far from the center.

Nice side shot with green crest on the upper petal. There could be also white or partially white and partially yellow forms.

This species was found in Germany dozen or so years ago and is spreading.

Fwd: Impatiens photographed at Dalhousie, H.P. : 5 posts by 3 authors. Attachments (5)
Here with some images of a colourful and attractive balsam snapped a few years ago at c. 2200m at Dalhousie growing in shady ditches beside the road leading to the town’s Public School.
Hopefully the Impatiens experts can suggest an identification or even a firm determination from the images provided.

This time it was easy – this is I. edgeworthii with characteristic spread lobes of upper lateral petals.
Compare pictures from Germany, where this species is spreading since beginning of XXI century:

Impatiens edgeworthii | Korina


Thanks for the DETERMINATION as Impatiens edgeworthii.
I think it would be useful for all members of this group to INSPECT the range of images posted of
They illustrate well INFRA-SPECIFIC variation.  To the un-trained eye/those unfamiliar with the genus IMPATIENS, some of the specimens photographed would appear to be DISTIINCT taxa – whether at varietal, subs-species or perhaps even species level…..
Stewart knew this large ‘yellow’-flowered species as very common in Kashmir @ 1500-2700m; he recognised a var. toppinii Hk.f. from Chitral on the basis of verticillate leaves.
Lancaster recorded this species from Gulmarg during a botanical tour in Kashmir.
According to ‘Flowers of the Himalaya’ this species is found at streamsides, rocks & grazing grounds @ 1500-2700m but only from Pakistan to Kashmir – making the Dalhousie population an extension of its range.  I CERTAINLY would not say the description of this species in this guide matches the specimens I saw at Dalhousie.
But I note the images from the GHNP on eFI which is also in H.P., extending its range further.
Given the challenges involved in ACCURATELY AND RELIABLY identifying Impatiens, I suggest the ranges of individual species of this genus are poorly known in the Indian Himalaya. I also consider that more recently described species, assuming they are valid, CANNOT, as yet, be meaningfully assessed as to rarity or abundance, since so few botanists can distinguish such species from existing ones and extensive surveys have not taken place.  Being described in more recent decades does not automatically mean they are rare, let alone, ‘endangered’.
According to Balsaminaceae in Flora of Pakistan (Y.Nasir, 1980) the TYPE specimen at Kew is from Kundau & Beas Valley – which is H.P., so Polunin & Stainton clearly got its distribution wrong in ‘Flowers of the Himalaya’.
Nasir describes it as one of the commonest balsams (in Pakistan and Kashmir), gregarious in shady & open places from 1800-3000m.  Morphologically very variable with the TYPE specimen differing from Pakistani plants in the subserrate leaves, larger lateral sepals (up to c. 8mm) and the gland-tipped bracts.  Apparently small-flowered forms of this species, often more branched occur frequently with ‘normal’ plants.  Collections from Dir in Pakistan were described in various manuscripts as separate species but Hooker never published these ‘species’.
Interesting that this species has naturalised in Germany.  It was not known to have naturalised in the UK by the time ‘Flora of the British

Isles’ was first published in 1962.  Nor by publication of ‘New Flora of British Isles’ in 1997.  Although Impatiens balfourii had been (briefly).


I can add that in 2015 I. edgeworthii was found in Netherlands for first time

Impatiens edgeworthi​i in Europe I. edgeworthii, coming from Western and Central Himalayas and rather rare in cultivation was found as spontaneous plant in Germany.
Baade H., Gutte P. 2008. Impatiens edgeworthii Hook. f. – ein für Deutschland neues Springkraut. Braunschweiger Geobotanische Arbeiten 9: 55-63. (in German)
However, there are some differences between descriptions in Flora of Pakistan and description given by German authors:
1) Nasir in FoP gives height 25-60 cm, whereas Baade and Gutte upto 180 cm!
2) Hooker f. gives color of flowers as yellow and red, Nasir as yellow streaked red in the throat, whereas Baade and Gutte give much broader spectrum: yellow, yellow-white, whitish and pale violet
3) Nasir gives two forms – one with bigger flowers and another with flowers much smaller
4) Some plants have flowers heavily streaked, some only very weakly (see pictures). Plant seems to be very variable.

If anybody has personal experience 🙂 with I. edgeworthii, please contact me

My photographs are already on Flowers of India.
I am attaching some more views from same population in Baramulla Kashmir, alt. 1600 m.
Here are my other uploads that may interest you:

In the mean time would it not be good idea to devote 2-3 days exclusively to this genus wherein members can upload all their collections Impatiens, to have them critically examined by you. Or else it may run concurrent with Brassicaceae week early November with separate subject line “Impatiens uploads:……………….(name/ID code for unknown sp.) from ……………(place)”


many thanks for your interest and idea of uploading Impatiens pics.
Please remember that I live and work far away from diversity centers of Impatiens (Poland) and have limited access to Indian floristic and taxonomic literature.

I can try my best, but I know only few species, big part of these only from pictures.


Impatiens edgeworthii in Germany


I have got information from Germany that plants of I. edgeworthii with yellow, white and pale violet flowers grow intermingled and there are no differences in morphology between differet flower colors.

Till now all pictures from native distribution known to me show plants with yellow, yellow-white or white flowers. Is there anybody who knows plants with morphology of I. edgeworthii and pale violet flowers?
