Premna sp.(Verbenaceae) for ID : 8 posts by 3 authors. Attachments (4 + 3).
Location : Lengpui, Mizoram. Altitude : 400 – 900 m. Date : 12-06-2014.
Habit : Middle-sized deciduous tree. Wood scented, durable for post.
Habitat : It grows wild in the secondary forest, etc.
Note : Leaves are eaten cooked with meats. Heartwood used for house post. Premna sp. ?


Flora Indica informs –

Premna latifolia Roxb. : – bark ash-coloured / corymbs axillary and terminal, compound/ wood is white, used for various economical purpose / leaves have pretty strong agreeable smell and used in curry. But, FBI informs leaves have 7 pairs of nerves.
Premna longifolia Roxb. : distrib. Bengal / bark ash to greenish brown / petiole 2 to 3 inches / corymbs terminal, large / smell agreeable. Nerves 6 pairs (FBI)
Premna integrifolia L. : it is connected with with several citations / sometimes thorny / upper half of leaf margin sometimes bears teeth / nerves 4 to 5 pair / leaves edible (KEW). Flora Indica informs (P. serratifolia) “the whole plant has a heavy unpleasant smell”.
I think your plant is one of the above three.


The options in my mail, referred here, was for the post at efi thread. I hope this post and the one linked above are same. Out of the three species I gave a short account on I would say that this tree is Premna serratifolia L.


It is quite confusing!!! The “Vawngthla .JPG” in efi thread is same as “Leaves.JPG” in the thread. 


Try to identify the plant with flower characters.
I am sending you characters of certain selected species of Premna found in our area.
so you please make sure that which characters(floral) resembles with your

specimen. see the attached word format.

Unripe fruits of Premna sp. (leaves of seedling/copyshoots are serrated?


Without calyx character it is hard to decide, I think it is Premna integrifolia L.


It is Premna milleflora C.B.Clarke
