Bengal Plants features only one sp., I. balsamina L. which has variable flowers. I have seen it in wild very often, garden escape. But I am not sure if this can be same.

These all the plants need to be examined with much details…..so specimens and details of dissected parts are needed.

Thanks, … Comparative images available at

To me appears similar to your earlier postings of Impatiens racemulosa Wall. ex Hook. f. & Thomson  as per images and details herein.


Again, compare with Verma D., Lavania S., Gogoi R. 2016. Recollection and lectotypification of Impatiens racemulosa Wall. ex Hook.f. & Thomson (Balsaminaceae). Webbia 71,1:1-4.


I don’t think this one is I. racemulosa.

Another problem is what species it is? Unfortunately, I don’t see enough to know it.
This is apparently late specimen, unfortunately without fruit. 


May I have copy of this paper.

This is not close to I. racemulosa rather it is close to I. florigera and I. tripetala

Thanks … for pointing out. You are right. … images on FOI do not at all agree with those in the paper Journal of Plant Taxonomy and Geography, 2016, Vol. 71, No. 2, 245–248.
Next is to figure out what species is this.

I suppose I. sulcata


Gigantic Himalayan Balsam Impatiens sulcata, I have seen this plant quite some times


I can’t agree – please compare shape of lower sepal here and in photo of I. sulcata on Flowers of India webpage
According to literature I. sulcata is growing along Karakorum and Himalaya ranges from northern Pakistan to Bhutan. I don’t know any reports of this species from other regions


Impatiens racemulosa


There was other thread with at least similar plant.
The same person (…) gave the same identification. Distribution pattern from literature (eastern Himalayas, Assam, Meghalaya…) and and general description (flowers violet, spur incurved) is in agreement with data given by both authors of relevant posts and this what is visible on the photo – we most probably have Impatiens racemulosa Wall. ex Hooker f. et Thomson!

But here leaves appears to be alternate and not opposite as in BSI Flora of India. Thus creating doubt.

Flora of India states leaves to be opposite, alternate or whorled as per attachment.

I am not sure what it is.
Looks somewhat similar to I. tripetala, but has longer and less curved spur.


Feedback from another thread:
In my opinion, neither this specimen by … nor the specimen by … from Mizoram are Impatiens tripetala. I have attached the description from Flora of British India, and underlined the portion describing the lip and spur. The spur cannot be called short in any of the two specimens. I have also attached the picture of lectotype of Impatiens tripetala from Phytotaxa 288 (2): 193–196 (2016). Neither of the two specimens appear close to it.


As this plant is with alternate leaves it id not match I. tripetala, but needs study

Again, I don’t think it is I. racemulosa – flowers are born in fascicles, shape of upper lateral petal is different.
I don’t see enough details to be sure what it is. More detailed pictures of flower parts could help…

just returned from a lovely trip to the north Bengal hills and forests. Five of us (Ruma Chakraborty, Indraneel Chatterjee, Joy Goswami and Shampa Goswami) visited Buxa Tiger Reserve-Chilapata Forests and Jaldapara WLS, and seen lots of wildlife, wild plants and birds.
Enjoyed bathing in Jainty river and hill streams at Buxa, the elephant ride thru dense forest at Jaldapara was exciting, the butterflies of
the hills were awesome….and the rhinos of forests simply amazing…the hills were clothed with wild flora….got spectacular views of the buxa hills on moonlit Purnima nights….
sharing images of wild flowers taken in the Buxa hills near Tashigaon (2000 feet).
plz help with the IDs.

Impatience sp. 


Obviously some species of Impatiens possibly the Common Balsam [Impatiens balsamia].


Thanks a lot for the ID… but this plant doesnt bear any resemblance to Balsam. plz identify the species…its some kind of hills species…never seen it in the plains

General shape of flower and type of inflorescence is characteristic for I. tripetala. Color is pale, but almost every species has sometimes pale forms.

I agree – this could be pale form of I. tripetala. Flowers are born in fascicles from leaf axils.
