Habit : Middle-sized evergreen tree. Habitat : Wild.
Location : Hualtu, Mizoram. Altitude : 600 – 1,400 m.

May I request you to pl. post a high resolution image of Thingbuhchang (2).JPG, to check with the keys.

Pl. check with Machilus parviflora as per these keys and as per GBIF specimens:
I am not sure.
Looks different from Machilus odoratissima as per GBIF.
This is Sarcosperma species. Most likely Sacrosperma griffithii.

Kindly have a look.

The fruits are not eaten by humans, but are eaten by wild animals like bears, palm civets, etc. Some white latex is coming out from unripe fruits, etc. ?

Sarcosperma arboreum ?

Thanks, …, What are the species reported and what are the keys?

Sarcosperma arboreum is recorded in Mizoram

Thanks, … What about Sacrosperma griffithii ? Is it reported ?

No

My one specimen was identified as S.griffithii at National Herbarium, Howrah, but this identification was wrong, I think

Yes, it should be Sarcosperma arboreum as I can see glandular pits the axils of abxial surface as in GBIF specimen as per keys from Flora of China:

2 (1) Leaf blade abaxially with glandular pits in axils of most main lateral veins 2 Sarcosperma arboreum
+ Leaves without glandular pits. (3)
3 (2) Leaf blade lanceolate, (1.5–)2–4(–5.5) cm wide 3 Sarcosperma griffithii
+ Leaf blade obovate to oblanceolate, 3–6 cm wide 4 Sarcosperma laurinum

MS, Jan.,2021/08 Lauraceae fam. for id
3 images.
Location : Dilkhan, Mizoram
Date : 10-01-3021
Habit : Large tree
Habitat : Wild

Difficult to say without seeing the arrangement of the fruits.

Is Sarcosperma a possibility?

Some possibility is there for Sarcosperma arboreum as per Hong Kong herbarium & GBIF– specimen 1 and specimen 2
But difficult to confirm with these images.


MS Oct,2021/30 Lauraceae ? for id: 6 images- 1 high res.

Looks so !

Any idea about the genus of this Lauraceae (?) member?

This is Alseodaphne. I do not know the species.

Maybe Persea… kindly also check Persea kingii

Persea is a new world genus. All the Asian members of Persea belong to Machilus.

To me appears to be the same as in earlier observations at Sarcosperma arboreum
Isn’t ?

I think, it’s different species.

Looks different from Machilus kingii as per GBIF specimens- one and two, due to persistent calyx.
What are the species of Alseodaphne listed in your book?
Pl. also post high res. images, to check the details.

Looking at the fruiting calyx, I still feel it is Sarcosperma arboreum only as per GBIF specimen.
