elementary question about Oxalidaceae : 1 image. 4 posts by 3 authors.

I have an elementary question about the family Oxalidaceae. I am following the posts of the members and the contributions by all are really fantastic. I read somewhere that the leaves of some plants in this family close when we touch them. Is it true of all the plants in this family or only some?


This is applicable to Biophytum only. It is so called because of this nature ‘Bio’ means life and ‘phyton’ means plant ie the plant is sensitive to touch. It was intially thought that only one species is sensitive to touch B. sensitivum. This was the reason why Carl Linnaeaus named all his received specimens around the world as B. sensitivum. Later we came to know that almost all unbranched species of Biophytum are sensitive to touch. They never close their leaflets as that of our common touch me not plant Mimosa pudica.
See the attached Photograph of Biophytum poterioides showing normal and closed leaves!!

Biophytum reinwardtii


As per efI site it does not match with colors.  Mine is with rose color. But reinwardtii is in yellow. 


Catalogue of Life and POWO gives Biophytum poterioides Edgew. ex Hook.fil. as syn. of Biophytum sensitivum (L.) DC.
Is it Correct ?


Also, may I get the keys of different species in India.


Biophytum poteroides is a distinct  species from B. sensitivum. I have reinstated the species (B.poterioides) recently and I will send you the paper or you can google it. 
The key for Indian species are yet to be created as there are still more mysteries to be unravelled.  I am working on it one by one.  Once I complete it I will send it to you. 


Thanks a lot, …
I got the paper at Reinstatement and lectotypification of Biophytum poterioides – 2019-(Abstract: Biophytum poterioides (Oxalidaceae), an enigmatic species, erroneously has been considered as synonymous with B. nervifolium Thwaites in recent treatments. Upon examining the types and other related specimens we prefer to treat it as an independent species. The name is reinstated and aA lectotype is designated here)
