Sterculia foetida…. wild almond tree



I also agree with …, as per images at Sterculia foetida L.


I think, leaves of Sterculia foetida are different.


Any keys from your book?



This is very rare tree. Found in only one village area in Mizoram


To me appears close to S.roxburghii (syn. of Sterculia lanceifolia Roxb. as per POWO) and as per details at
https://singapore.biodiversity.online/species/P-Angi-003284?imageId=0
https://tropical.theferns.info/viewtropical.php?id=Sterculia+lanceifolia
Can you send a clear image of the leaves?
