As per efi thread:
In I.acaulis the wing petals are bilobed where as in I. scapiflora it is 3-lobed;
.

for id 21 07 2011 mm1: begonia i think
photoraphed in amboli on a roadside rocky cliff, in very pure light the flowers were mauve in color and approximately an inch long would very much appreciate an id

It is Impatiens sp (most probably I. acaulis) of Balsaminaceae family.


This is Impatiens acaulis (Balsaminaceae), This plant is stemless, very often mistaken for Begonia sp.

Color variation in Impatiens acaulis???:
Here is the photograph of Impatiens acaulis in white colour.
Photographed at Naneghat (Maharashtra on 9.9.2012)
Needs experts comments…

I remember, … posting this on Indian Flora, here is detailed discusssion


It looks almost like Impatiens acaulis Arn., except perfect white coloured flowers. I have come across a few light pink and pinkish white fld I. acaulis and I. scapiflora in wild mixed up with pink coloured plants. How about this ? Is it mixed up in the pink fld plants or entire population has white fld plants ? If the entire
population has white fld plants, then it would be interesting and worth studying it in detail. I would appreciate if some pollen and seeds are sent to my address

Impatiens acaulis
Another Impatiens species observed on rocky faces of mountains near the plateau. An occasional observation. Similar to elsewhere in Western ghats.


I think this is not very common at Kas.


Interesting looking with exceptionally long tail (spur)

These flowers was seen on the rocks beside a waterfall in Tamhini ghat near Pune, MH in Aug 2019.
I guess this is Impatiens acaulis.
My first sighting of this beautiful flower.

ID is correct !!


Beautiful flowers …, Thanks for sharing,


Thanks … They are really beautiful.
Some 6-7 years ago, one of our members had a pic of these flowers on their FB page and from then on I wanted to see the flowers.
It took these many years for me to finally behold them with my eyes.

Congrats …, I understand your feelings, was so much happy when we saw the original habitat the first time,
