This one is from Triund. I could tell it was likely from the Brassicaceae family but could not find an exact ID. Please advise.

31 July 2016. Pl. check for some Arabis (comparative images available here for images in efi so far) species ? Thank you … for the suggestion. I think my plant is close to Arabis pterosperma. Here are the leaves I photographed during my trek on Saturday. .
Captured – Madhmaheshwar Uttarakhand
Alt. 3900m asl.
Alliaria petiolata I hope I think it looks different from the images at Alliaria petiolata (M.Bieb.) Cavara & Grande It appears to be some Arabis species.
Pl. check Arabis pterosperma Edgew.
To me it appears close.
Yes Sir, it seems nearby, actually, I have a single image and don’t have a sample for more confirmation. What are the species of Arabis reported from your area? Arabis amplexicaulis So we take it as Arabis pterosperma Edgew. . References:
