Arabis bijuga Watt, J. Linn. Soc., Bot. 18: 378 1881. (Syn: Arabidopsis mollissima var. griffithiana O.E. Schulz; Arabis macrantha C.C.Yuan & T.Y.Cheo; Arabis pangiensis Watt; Parlatoria griffithiana Boiss.);
Arabis bijuga G. Watt from above Qazi Gund, Kashmir: While driving down the Jawahar tunnel towards Qazi Gund on Pir Panjal range, I was struck by a species of Arabis with unusually large flowers, almost twice the size of closely related species Arabis amplexicaulis. It was after I studied the flowers carefully and hairs on stem that I realized it to be Arabis bijuga, a species often confused with former, but distinct in larger petals 12-15 mm long (as against 7-10 mm in Arabis amplexicaulis), usually in diverging pairs (against equally spreading), and stems and leaves with mostly stellate hairs (as against mostly simple hairs).
