This is not the same species as in the other thread, Sawmliana ji posted -
https://groups.google.com/g/indiantreepix/c/Je5w66tI7lM/m/aZnjMoziAgAJ.. Here flower is larger, peduncle is longer, flower is funnel shaped, unlike rather campanulate shape of
Merremia.
And to my disappointment there is no fruit picture in the submitted set to prove my suggestion!
Another disappointment is that perhaps Sawmliana ji is in no position to upload original plates of this species.
Moreover, Camonea kingii (Prain) A.R.Simões & Staples is not listed in Flora of Mizoram!
Should I accept Operculina turpethum then?
( I will skip the "winged stem" part! )
NO
- some of the peduncles are longer than 3 cm here
- anthers are different from Operculina turpethum (check the paper I mentioned in the other thread)
If Sawmliana ji could show me a pair of tiny auricles at the petiole attachment site of the stem!!!
