MS, Dec.,2020/16 Quercus sp.(franchetii ?) for id.: 2 images.

Looks matching !

Quercus franchetii

Is Quercus franchetii (as identified) listed in your area?

No

Then why did you suggest it?

May be possible since it is adjoined to Myanmar ?

What are the species listed in your area?

Quercus acutissima, Q.brandisiana, Q floribunda, Q.griffithii, Q.helferiana, Q.leucotrichophora, Q.lineata, Q.semicarpifolia and Q.semiserrata are recorded in Mizoram

After going through all the species listed by you, the closest I can go is Quercus lanata subsp. lanata as per GBIF– specimen 1 and Specimen 2. POWO and Catalogue of life give its distribution in the area.

Quercus lanata Sm. ??

---

Why not Quercus semecarpifolia Sm. as per images and details herein?

---

I guess leaf pattern is more close to Q. lanata.

900 × 675

650 × 411
3008 × 2000

---

can you tell us the sources of these photos?

---

This is not Q. semecarpifolia. First reason, Q. semecarpifolia is a high altitude oak. It normally starts growing from 2500m to 4000m. Quercus lanata/ oblongata/ leucotrichophora grows from 1300m to 3000m.

Secondly, the leaves of Q. semecarpifolia are oval in shape with entire margin or with sharp teeth (normally on young shoots). The underside is brown/golden in colour. The leaves of Quercus lanata/ oblongata/ leucotrichophora are oblong in shape with toothed in apical half. The underside is white/ silver or sometimes yellowish white. I am attaching some photographs of leaves for better understanding.

Thanks, … Do you agree with … id ?

Yes, It’s Q. oblongata (syn. Q. leucotrichophora/ Q. lanata).

Is not Q. lanata is separate from Q. oblonggata (Syn Q.  leucotrichophora)

WCSP gives both Quercus lanata Sm. & Quercus oblongata D.Don as accepted species as per details at links.
Pl. clarify.

The story of Q. lanata and Q. oblongata (Syn Q.  leucotrichophora) is very complex. Some authors consider them synonyms and some independent species. The recent classification of oaks has considered them the separate species BUT If you see the specimens used to describe the species, they all are located in Europe or the US. The Flora Of China considers them synonyms after studying them in the natural habitat. 

IMHO, 

1. For describing a species one must study it in its natural habitat i.e. Himalaya and adjacent region. 

2. All the features used to describe Q. lanata and Q. oblongata is more or less the same. Some separate them with big acorn cups for Q. lanata and small for Q. oblongata but I observed so much variation in the size. Another feature used is the number of teeth on the leaf margin, which is also very variable in Q. oblongata that I have observed in its habitat (Himachal and Uttarakhand).

3. Another doubt is the distribution of Q. lanata. There are 2 views on this:

3a. It grows from west Himalaya to East and continues into China, Myanmar, North Thailand and Vietnam. 

3b. It is absent in western Himalaya and starts from mid-Nepal to Sikkim, WB, Bhutan, Arunachal Pradesh, China, Myanmar, North Thailand and Vietnam. 

4. The photographs I saw of Q. lanata from an arboretum located in Spain is the same as of any Q. oblongata I have seen in Himachal Pradesh and Uttarakhand. 

5. There is also a third view of this conflict. It says that the Q. oblongata is a subspecies or variety of Q. lanata.

In reality, there is not enough data collected and research done to consider Q. lanata a separate species for now. China has done some ground research but nothing from India yet. There is a need for a proper field study on the species in India (not just Q. lanata but many other oak species).
I hope this will be helpful.

Thank you … for the enlightenment.

Yes Quercus leucotrichophora the underside of the leaf is white in colour

Quercus oblongata D.Don.  : 4 posts by 2 authors. Attachments (6)
Sharing some pictures I guess is  Quercus oblongata D.Don. syn:  Quercus leucotrichophora A.Camus shot at Jitpurphedi Kathmandu on 27 August 2016 at 6200 ft.
If correct ID Nepali names would be :
तिखे बाँझ Tikhe Baanjh /  बाँझी Baanjhi / खसरांत Khasaraant

Fruits seem to differ from images at Quercus oblongata  

---

Link

Quercus serrata ?? but not listed in Nepal !

Most of the fruits look alike. Very difficult for me to ID correctly.

---

Appears close to images at Quercus oblongata D.Don as per comparative images at ‎Quercus

---

Thank you … for final validation of ID.

Syn: Quercus leucotrichophora A. Camus

Quercus oblongata : 2 posts by 1 author.

I did not want to join the group as I only have one question and maybe that could be sent to those listed under Quercus oblongata.

/species/a—l/f/fagaceae/quercus-robur/quercus-oblongata

I would like to ask

Many now regard Q. oblongata as the correct name but has anyone seen the type specimen of Q. oblongata, or has anyone seen the first article that says this is the correct name for Q. leucotrichophora?

Also literature usually states that this species ripens fruits in 2 years but photos I see show annual ripening, sometimes ripe early the following year. Does anyone have observations on this? The Chinese say Q. leucotrichophora is biennial fruiting, Q. lanata is annual.

It seems likely that Q. oblongata, leucotrichophora and lanata are the same, in which case Q. lanata would be the correct name.

Also is there any record of Quercus tungmaiensis in India?

This is from Arunachal Pradesh and seems to be that species.

Quercus glauca Thunb. ??

I think more close to images at Quercus oblongata D.Don arther than those at Quercus glauca Thunb.

---

You seem to be right

identify this acer species: 3 images.

Isn’t it Quercus.. leucotrichophora.. ?

---

We have a page for this species at

To me also appears close.
