Swertia -1 from Kalatope for id al210911:
Today I am posting two Swertia sp. observations from Kalatope Location Kalatope, Chamba
Altitude 2100 mts
Habit herb
Habitat wild
Plant height 2 feet
In this one the white part near the nectaries is like eyelashes and the flowers are 1.2 cms across

4 petals, single fringed gland suggests Swertia alata, but leaves seem to be narrower.

The leaves of this one at the base are 4 cms long and 3 cms wide.. Does that fit the description of S. alata…

I think that should be alright. They are usually ovate-cordate, 3-7 nerved.

THis one should be Swertia angustifolia, which has narrower leaves and darker dots on corolla.

I think Swertia nervosa (Wall. ex G. Don) C. B. Cl. as per images herein.

It should be Swertia alata as per GBIF– Specimen, FOI, IIIM

Swertia angustifolia (I had actually identified it as S. alata, as per images in efloraofindia, but has revised the identification in view of posts in the current episode) from Himachal [Shimla; 2000 m asl]

I think Swertia nervosa (Wall. ex G. Don) C. B. Cl. as per images herein.

It should be Swertia alata as per GBIF– Specimen, FOI, IIIM

Looks like Dendrobium gracilicaule

Looks like Prosthechea sp

Two different species? First looks like Swertia nervosa!

It’s not monocot plant, Dicot only, Gentianaceae member, Swertia,
I agree with …

Thank you so much sir for Ur kind responses and yes it’s Swertia alata or nervosa according to Ur and other sources responses …

Yes, it should be Swertia alata as per GBIF– Specimen, FOI, IIIM

Swertia…. ????

I think it is close to images at Swertia alata C.B. Clarke

Herb from NE India for Id:
Gentianaceae family Herb from NE India. No other information available.

It may be Swertia chirata of Gentianaceae.

To me appears close to images at Swertia nervosa (Wall. ex G. Don) C. B. Cl.

He thought it to be a new species! Unfortunately nothing can be done now because most of his collections are lying without any label due to his premature demise.

I guess very much close to S. nervosa!
Actually this photo was taken by me from Blue Mountain NP, Mizoram, and I was unable to identify this. Then I sent to MK Pathak Sir. But it was unknown to me that he sent it to you for id. After that he passed away.
Anyway I kept it as Swertia nervosa only.

Thanks, …, Can anyone tell what are the species of Swertia listed in Mizoram?

Swertia angustifolia var. pulchella, S.cordata, S.nervosa, S.paniculata are recorded in Mizoram

Thanks a lot, … Hi, …, Do you have an image showing the lower parts?

One lower leaf is visible matching to S. nervosa!

This is Swertia nervosa as per keys and discussions at Swertia nervosa (Wall. ex G.Don) C.B.Clarke

Sorry. Considering cordate, sessile lower leaves (though not very clear), it should be Swertia alata only as per keys and discussions at Swertia nervosa (Wall. ex G.Don) C.B.Clarke
