Flora of Chakrata 2012: Machilus duthie for validation:
This one was shot from Chakrata region in May 2012, a mid-sized tree with glabrous leaves, the identification was attempted by refering to Flora Simlensis….
I could identify this as Machilus duthie King, though no fruits could be seen… attaching the illustration from Fl. Sim. for reference. Hoping to get response regarding validation/correction…


Agreed … New name is Persea duthiei


Very nice upload of a Lauraceae member.
Can’t validate but I think you are correct. Attaching an illustration from Flora of Pakistan.

This small tree was shot from Chakrata area in May 2012.. I could get to id as Persea duthiei Syn. Machilus duthiei.. Please give your inputs and correct/validate the id..


Leaves 5-10 inches long, lateral nerves 12-20 pairs indicate it as P.duthiei.


It looks me Persea duthiei too.

Tree seen on way to Nainital on 23/3/13.
Hope this is the Lychee tree but not sure.
Posting for validation.


I think this is not Litchi because leaf of Litchi is different from this plant.


If not Litchi, could you identify the tree please?


Agree with … It looks different from Litchi inflorescence and leaves.
Let the expert to conclude.
I have no idea what plant it could be.


Could it be Avocado Tree, Persea Americana?


Adding pictures of Persea americana, Avocado taken in Sri Lanka.
I hope these pictures help in the id of the posted tree.
These were taken in Nov,2010.


Appears like Duthie’s Bay Tree


Thanks for the id. It does look like it.

Kindly help in ID of this tree photographed from along Chopta Mandal road in Uttarakhand in June, 2013.

I think the same tree from Baijnath, photographed in April. Attachments (2).


The tree is a Lauraceae member, must be Persea species.


Yes …, Persea duthiei looking at globose young fruits.

SK 3709 21 March 2023:

Location: Ranibari, Kathmandu
Date: 21 March 2023
Altitude: 1370m.
Habitat : Wild

May be from lauraceae.


To me appears close to images at
https://efloraofindia.com/2012/05/03/machilus-duthiei/
Pl. check.


I think this is Machilus edulis King ex Hook.f.


I could not find its distribution in Nepal.
Could it be Machilus duthiei King ex Hook.fil. ??
https://efloraofindia.com/species/a—l/l/lauraceae/machilus/machilus-duthiei

Machilus duthiei has 14-20 pairs of lateral nerves of leaves, which it is not.


This may be even a new species!


I feel it looks different from GBIF specimens of Machilus edulis, both in leaves and inflorescence arrangement.

I still it is more closer to images at
https://efloraofindia.com/2012/05/03/machilus-duthiei/
(lateral nerves are also in the range of 14 or so)


Here is the key to the species of Machilus in the Indo-Burmese region. Please help yourself. I still think that this plant may prove to be a distinct species, close to M. duthiei.

SK 3716 08 April 2023: 8 very high res. images.

Location: Chandragiri, Kathmandu, Nepal
Altitude: 1975m.
Date : 8 April 2023
Habitat : Wild
Lauraceae for ID !


Very close to Persea macrantha


Machilus again, if not Phoebe (distinguishable by fruits only). I will check the species.


If the ID is correct according to …,  new name should be Machilus glaucescens Wight ??


Machilus odoratissima Nees.


Why not Machilus duthiei King ?


Please consult the key to the species of Machilus which I sent earlier and you will have your species.


I consulted these.
To me, leaf nerves look like 16 or more.
