Request for assistance in species identification: 2 high res. images.
Kindly help me identify this Dendrobium species. Searches on the internet show similarity with Dendrobium eserre Seidenf. but a clear image of the flower was not found.

Something close to Dendrobium eriiflorum Griff. ??

---

I am thinking this looks like Dendrobium eriiflorum but cant confirm. Cant make out the size. Cant make out if the inflorescence is going up or hanging down.

---

The average stem length is 8-10 cm, tapering and inflorescence stalk length 5-6 cm, upward.

MS, Nov., 2023/01 Dendrobium sp. for id.: 3 images.
Location : Hmuifang, Mizoram

Is it Dendrobium denudans..?

---

Dendrobium porphyrochilum Lindl.

---

… has sent these pics to me before while I was traveling. Right now I am not confirm even when he provided some dissections as I have yet to see a spread up lip. But this looks close to Dendrobium eriiflorum. Then there was one more species, Dendrobium sessanicum too.

---

Isn’t that sp. endemic to Arunachal Pradesh, … ?

---

Yes so far. But most of the plants are supposedly described as endemic from somewhere. I also doubt that they are same species.

---

OK
