Tried all avenues but no success for ID.

Have you check comparative images at Impatiens ?

Yes …

I could also not find a match as per comparative images at Impatiens

Sorry, I don’t see enough details…
This is particularly difficult group with some unresolved problems and without detailed studies it is impossible to be sure.

Please, have you looked at what I know as Himalayan Balsam aka Impatiens glandulifera? Did you look at Impatiens oxyanthera?

Yes I did but no luck.

I think I. glandulifera is closest ID, especially looking at spine-tipped sepals and bracts

I guess plant size, flower color, leaf margin does not match.

Having such long forward projecting appendage on dorsal petal it must belongs to Impatiens jurpia complex…
In Impatiens jurpia complex there are at least four described species….
Owing to its pubescent leaves, white lateral united petal of flower with pale yellowish throat having some red markings, red saccate lower sepal abruptly constricted into a spur and quite longer appendage on dorsal petal it should be Impatiens jurpia….

Can you help me with herbarium and images with description?

please find the attached paper on The Impatiens jurpia Complex: Studies in Balsaminaceae: X C. Grey-Wilson
You can also find description on Indian biodiversity portal site and herbarium images on gbif site…

I guess it is matching. Only I wish if I could see matching images of it in the net.


I’d of Impatiens from Sikkim: 1 high res. image.
kindly help in the identification of an Impatiens spotted from Sikkim

Impatiens cathcartii Hook.f.

I am not sure as per images at Impatiens cathcartii
Do you have any other images?

It matches closely with Impatiens jurpia

I. jurpia and I. cathcartii although typically differentiated by absence of spur on Standard (I. cathcartii) and distinct spur (I. jurpia), but both species show variation from gibbous condition to distinct spur. The only feature seeming to be fixed is glabrous leaves and stem in I. cathcartii and hairy in I. jurpia. By that count it looks I. cathcartii.
