Balsaminaceae, Geraniaceae and Oxalidaceae Week: Natural history of Balsaminaceae : 4 posts by 4 authors.
I read this article on which the origin and distribution (Phytogeography) of Indian Balsams discussed, with special focus on Nilgiris species. I hope this article is worth reading.
Definitely worth reading … thanks for sharing…
Never knew about so many Balsam species.
