This is from Kumarghat Tripura
Please identify the species

I think could be Diospyros sp.

I do not think it is Diospyros sp.

Mostly Miliusa velutina or Other species also only. Annonaceae.

Miliusa dioeca (Roxb.) Chaowasku & Kessler. ??
Syn : Miliusa globosa (A.DC.) Panigrahi & S.C.Mishra

It may be Miliusa globosa if id at the following link is correct:
I could hardly get any inf. on net except the following:
It looks different from images of Miliusa velutina at

Many specimens of this species in gbif has been renamed to some other species described a very years back as per

Miliusa globosa is rather a dubious name with unclear identity for the application of the name. So, for this species, Miliusa dioeca has to be applied instead.

Am familiar with all the species present in Kerala. But this one is not familiar to me..!!

I think it is Miliusa horsfieldii

It may be Miliusa globosa if id at the following link is correct:
I could hardly get any inf. on net except the following:

Miliusa indica Lesch. ex A.DC. ??

It is different as per images and details at Miliusa indica

Also no distribution as per Miliusa indica Leschen. ex DC. (India: West Bengal, Karnataka, Tamil Nadu and Kerala; Sri Lanka)


Fissistigma sp. for ID : 4 posts by 3 authors. Attachments (1).

Location : Tleu, Mizoram. Altitude : ca. 900 m. Date : 25-05-2012.

Habitat : Wild

Seems like miliusa tomentosa

What are species reported from your area?

Miliusa globosa and Fissistigma polyanthum are recorded in Mizoram

Appears close to Miliusa globosa (syn. of M.dioeca as per POWO) as per GBIF– specimen.
