Eriolaena sp.,


Any keys?


Not listed in Flora of Mizoram. I think it is Eriolaena spectabilis


Yes, you seem to be right as per POWO specimens- one
I checked distribution of all the species in BSI Flora of India.
There is another species Eriolaena wallichii, which is shown distributed in eastern Himalayas as per POWO, but looks different.
