Kindly chk Lasianthus spp 


As suggested by …, pl. check with species as available at

What are the species of Lasianthus found in your area ?

Lasianthus spp. found in Mizoram are : Lasianthus biermannii, L.hookeri, L.lucidus & L.tubiferus.


After perusal of these species, mainly in Flora of China as per given links, I think it is more closer to Lasianthus inodorus syn. Lasianthus tubiferus
