Brassicaceae Week : Rorippa indica (L.) Hiern from Hooghly:
Attaching images of Rorippa indica (L.) Hiern.
Species : Rorippa indica (L.) Hiern
H & H : wild herb of about 1 foot
Date : 6/5/12
Place : Hooghly
I have not seen it, but the third photograph shows bracts below flowers suggestive of R. benghalensis, although pedicels are not slender.

Thank you very much for the ID.
I was also hesitant, since illustrations of R. indica in FoP & FoC were a bit different.

Rorippa indica (L.) Hiern from Assam KD )08 April 2015 : 5 posts by 3 authors. Attachments (4) 
Attached images seem to be Rorippa indica (L.) Hiern. Please validate.  
Date :12.04.2015
Location: Assam
Family : Brassicaceae
Genus & species : Rorippa indica (L.) Hiern  (?)
Habitat: Grows wild on ditches
Habit :Herb 
Hirsute nature, auriculate leaf, bracteate raceme suggest Rorippa benghalensis DC. (H. Hara)?
efi page on Rorippa benghalensis 
Presently I am unable to confirm anything, please check my latest upload 
I only suggest that in addition to the points I have written earlier flowers of benghalensis are pale yellow while indica flowers are yellow (as per FoC).
Flora of British India (ah! old lit. again!) informs leaf-like bracts of benghalensis are shorter than pedicels.
I have confusion, yet I would select benghalensis  for this species.

Location: Kamrup district
Family : Brassicaceae
Genus & species: Rorippa sp
Habitat: Grows wild on waste place
Habit : Herb
Flower : Yellow in colour
According to Bengal Plants -
i) pods hardly longer than pedicels = Nasturtium palustre DC.
ii) flowers without bracts = N. indicum DC.
iii) flowers with bracts - N. indicum var. benghalense
In addition to above Fl. Br. Ind. has -
iv) N. montanum Wall. = less robust than N. indicum, with smoother & less divided leaves, slender pods 1 to 1.5 inch (0.5 to 0.75 in. in N. indicum); can be found in Sikkim to Punjab. Khasia hills

As per efi thread:
According to Bengal Plants -
i) pods hardly longer than pedicels = Nasturtium palustre DC. (now syn. of Rorippa palustris (L.) Besser)
ii) flowers without bracts = N. indicum DC. (now syn. of Rorippa indica (L.) Hiern)
iii) flowers with bracts - N. indicum var. benghalense (now syn. of Rorippa benghalensis (DC.) H. Hara) 
As the flowers appears to be with bracts, it should be Rorippa benghalensis (DC.) H. Hara
