Thanks, …. I think 1st illustration may be Gratiola hyssopioides L., which is as syn. of Lindernia hyssopoides as per details herein.
Gratiola hyssopioides Roxb. is a syn. of Dopatrium lobelioides (Retz.) Benth.


   

Images at Dopatrium lobelioides (Retz.) Benth. page (in Flora of Peninsular India) are of Lindernia hyssopoides and not of Dopatrium lobelioides as per images and details herein.
Pl. correct.
