Rorippaspecies in India & eFI with details & some keys

It looks me Arabadopsis thanliana

Appears to be Arabidopsis thaliana

My attached images are not Arabadopsis thanliana. In Arabadopsis thanliana flower is white, sepal and petal present (According to Flora of India, Vol. 2, page 231). But my sp. has no petal, only 4 sepal, erect, green in colour with pink spot (observations after dissecting the flower). I hope, it may be Rorippa dubia but not Arabadopsis thanliana.

Clearly not Arabidopsis thaliana which is much more delicate plant. Habit suggests Rorippa, and R. dubia (syn: R. indica var. apetala) looks likely ID.

Location: Kathmandu, Central Nepal
Altitude: 1825m.

Habit : Wild
Rorippa dubia (Pers.) H. Hara or Rorippa indica (L). Hiern ??

This may be Rorippa dubia (Pers.) H. Hara as I do not see any petals (only have the sepals) in the flower as per Keys in Flora of China and as per FoC illustration.

Seems to be correct …

I too think so
