Have you check comparative images at Impatiens ?

---

Yes …

---

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

---

---

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

---

---

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

---

---

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.
