Kindly identify it

Goniothalamus sp.

I tried to go through comparative images at Annonaceae  

I could only feel that it may be some Monoon or Polyalthia species

It could be a species of Alphonsea

Alphonsea elliptica ??

Thanks, …, for the genus id.
Two species may be reported from the area as per Alphonsea
Alphonsea lutea (Roxb.) Hook.f. & Thomson looks different as per images, details and references herein.
It appears close to the other species, Alphonsea ventricosa as per
Plant illustrationsPOWO, GBIF (high resolution specimens)

Annona glabra?

No !

Annona glabra is much different.

Thanks, …, for the genus id.
There are only two species reported from India as per Alphonsea
It looks different from Alphonsea lutea
To me it appears close to the other species Alphonsea ventricosa as per

Thank you very much. I agree with your identification. Alphonsea ventricosa


Edible fruit tree ID : 16 posts by 5 authors. 3 images- 1 & 6 mb and 189 kb.

I would appreciate your help in identifying this tree species.
Its a medium-sized tree. Fruits edible.
Photo taken: June 2020, 100 m elevation.
I do not think its Diospyros.

Kindly check Myristicaceae, genus Knema.

Knema tenuinervia subsptenuinervia W. J. de Wilde ??

Thank you …  One more photo hope it helps.

Please try to post such clear images. This is some Miliusa species of Annonaceae.

Can it be Miliusa roxburghiana (Wall.) Hook. f. & Thomson as per GBIFSpecimen ?
This is the species which I found to be close as per Checklist of Nepal.
I could not find a match as per comparative images at Annonaceae

Thank you for your concern.
I got a fresh photo from the field. Please have a look.
According to recent Nepal flora, Milliusa roxburgiana is single seeded.
But it has 12-17 seeds in a fruit.
Maybe this photo helps.

This is a species of Alphonsea

Uvaria hamiltonii Hook. f. & Thomson or Alphonsea ventricosa (Roxb.) Hook.f. & Thomson ??

Thanks, …
It looks different from Uvaria hamiltonii Hook. f. & Thomson as per GBIFspecimen 1 and specimen 2
It is Alphonsea ventricosa only as per images and details herein and as per GBIFSpecimen, which is found in Bihar, West Bengal, Assam and Meghalya; Bangladesh as per BSI Flora of India (though not recorded in Annonaceae in Flora of Nepal, published online in 2012 and also in Checklist of Nepal).

Thank you very much. Based on fruit, Bark and leaf characteristics you rightly pointed that it is Alphonsea ventricosa.
Yes its not been reported in Nepal flora which is not a surprise to me. Nepali botanists need to work a lot on tropical plants.
