MS, Dec., 2022/03 Herb for id.: 2 images.
Location : Tamdil, Mizoram

Appears to be from Fabaceae.

---

Or maybe from Amaranthaceae.
I also tried Lamiaceae, along with these two families.
But unable to get close.

Alternanthera sp. ??

---

I also thought so, but no match with existing species.
What are the species reported from your area? and Keys?

Only Alternanthera sessilis is recorded in the Flora of Mizoram

---

Looks different from it as per

---

Crotalaria sp., I think.

---

I tried at https://efloraofindia.com/2011/02/20/crotalaria/ and other related species, but could not find anything close.

Does not seem to match as per

yes, it looks more closer towards Lepidagathis..

Crotalaria sp.
Check with local floras.

What are the species and keys in your book?

---

2 images.

---

Does not match with any of these Crotalaria species.

---

this is Acanthaceae member, the leaf and the bracts of inflorescence indicates that. some how i am not reaching the genus..

---

No distribution but could it be Justicia flava (Forssk.) Vahl ??

---

I do not think so.

What are the species of Justicia reported from your area with Keys?

---

2 images.

---

Can it be Justicia khasiana as per POWO specimens: one, two and three ?
I am not sure at all.

Thanks a lot, … Yes, it appears so. Finally, you have solved the mystery.
