Impatiens amphorata Edgew., Trans. Linn. Soc. London 20: 39 1846. as per efi thread;
Common name: Amphora Balsam

Impatiens devendrae Pusalkar: 8 very high res. images.

Location: Jumla, Nepal
Altitude:  2481m.
Date: 18 August 2021 
Habit : Wild
If ID is correct, it would be a new sp. for Nepal.

Though our young Balsam expert will have his say, I think you are right in identification..

These plants look similar to what was identified recently as I. devendrae.
There are many less or more similar observations on iNaturalist, with and without rusty markings, with more or less inflated lower sepal, with more white or more rosa (even yellow) flowers and with different shapes of spur.
Several years ago I found old illustration very similar to I. devendrae. Plant there was called I. amphorata.
Now, Akiyama (Akiyama S. 2021. Impatiens (Balsaminaceae) of Nepal (1) An Identification Key and Taxonomy of the Species of Sections Uniflorae, Fasciculatae and Axilliflorae. Bulletin of the National Museum of Nature and Science. Series B, Botany 47(2): 79-101.  and Akiyama S. 2021. Impatiens (Balsaminaceae) of Nepal (2): Taxonomy of the Species of Sections Racemosae and Sulcatae. Bull. Natl. Mus. Nat. Sci., Ser. B, 47(4): 193–220. DOI: 10.50826/bnmnsbot.47.4_193 use name I. amphorata.
I think for the time being these plants should be called I. amphorata.

Impatiens amphorata should not be a synonym of Impatiens bicolor, which has yellow and pink bicolor flowers.
The name Impatiens amphorata was originally used for the pink colored species
This species is now Impatiens bicolor var. devendrae, as per,136272,0,2.html

Any opinion on your two sp. ??

I just saw Wojciech’s post in this thread which I earlier missed. I am happy to see that this plant is now called Impatiens amphorata. Many years back Wojciech had said in this forum that the species which was described as Impatiens devendrae, was the same which was originally called Impatiens amphorata, but for some some reason got mixed up with Impatiens bicolor. I will happily go with Impatiens amphorata. I too think that … plant is Impatiens amphorata, known from Nepal according to Impatiens (Balsaminaceae) of Nepal (1) by Akiyama.

Paper by Singh et al. produce a lot of noise and give little information…
In our paper (see  Misinterpretations and_plagiarism  in_a_publication about_Himalayan_Impatiens polemics_with_the paper_of_Singh RK_et_al_2021) we polemize with Singh et al., showing weakness of field and literature studies.
We don’t include I. devendrae in our paper, as we have not enough material for this difficult group.

If time allow, I will prepare a file dealing with I. amphorata/I. devendrae and add it to my project on RG. I don’t think however I will be able to do so before autumn, as my field season starts soon.



Impatiens devendrae Pusalkar ??:
Request for your kind opinion on this sp.
West Nepal at 2500m in August.

your plant looks like plants named I. devendrae in efloraofindia portal. Lower sepal seem less inflated than in original description by Pusalkar, but I saw pictures of plants with less or more inflated lower sepal, almost completely white or completely rosa, even yellow flowers, with strong or weak markings, as well as curved or spiralled spur.
In Flora of Uttarakhand Pusalkar wrote about variability of this group, describing plants with smaller white and unmarked flowers. This way decision where I. devendrae/ amphorata starts and where it ends need more studies in field.
However, compare old illustration on plantillustrations portal under name Impatiens amphorata. Also Dr. Shinobu Akiyama in her newest paper do not mention I. devendrae, but mention I. amphorata. Here I. amphorata is only mentioned in key.
Full description will be published later and then we will be able to see what she includes into I. amphorata.

All links say it is syn. of I. bicolor but it does not look like matching.

General sources are sometimes deadly wrong…
Check this: Hooker J.D. 1881. Impatiens amphorata. Curtis’s Botanical Magazine 107, tab. 6550 on www.botanicus org.
There is old illustration almost ideally matching your plant.
Check also newest paper: Akiyama S. 2021. Impatiens (Balsaminaceae) of Nepal (1) An Identification Key and Taxonomy of the Species of Sections Uniflorae, Fasciculatae and Axilliflorae. Bulletin of the National Museum of Nature and Science. Series B, Botany 47(2): 79-101.
It is freely available now.
True I. bicolor has bicolored, yellow and rosa flowers.

I shall do that.

May I have your opinion ?

I think I agree with …

That means bicolor ??
