Wild guess seems to Casearia sp, check once with local floras which one mentioned there …,
matched characters are Alternate leaves, inflorescence axillary clusters with small peduncles and fruits with lobes or slight pyrens,
Thank you … Yes it could be member of Caesaria. I will check it and update.
Does not shape of drupe look different?
Please compare with Drypetes subsessilis of Putranjivaceae.
Thank you very much for your kind cooperation. Your suggestion is very helpful. It resembles more with D. assamica.
I think we are pretty close.
…: I think its more close to Drypetes assamica.
There are three closely related species: D. assamica, D. bhattacharyae and D. subsessilis. Here, your fruits are subsessile which suggests D. subsessilis. For confirmation, you should have the male flowers. The male flowers in D. subsessilis are up to 5 mm in diameter with 3-4 stamens while in D. assamica, the male flowers are about 10 mm in diameter with 8-12 stamens.
In case you wish to treat them as conspecific, then the name D. subsessilis will have to be adopted for the combined species.
Thanks for the detail information about the species. I will wait for flowers and update you about the flower characters.
Yes, … is correct it’s Drypetes only, check properly for sp., Thank you so much … for enlightening from the post,
Is Drypetes listed in Nepal? Looks like a new sp. for Nepal !
You are right. No Drypetes has been recorded so far for Nepal but two species are there in Bhutan (assamica and subsessilis).
Thanks a lot, …, for nailing this id.
On examination of specimens in GBIF, I feel it is Drypetes assamica and not Drypetes subsessilis as per specimens herein and as per the following specimens:
Also matches with … images at Drypetes assamica
Look for flower in Jan- May !
Thank you very much for your support to nail it down. yes, it is
Hope I will be able to collect flowers soon and update you!
