Lindernia dubia is a species of flowering plant known by the common names yellowseed false pimpernel and moist bank pimpernel. It is a member of the “new” plant family Linderniaceae, and it is sometimes treated as a member of the families Scrophulariaceae and Plantaginaceae.

It is native to much of the Americas from Canada to Chile, and it can be found on other continents as an introduced species. 
It grows in wet habitat, such as riverbanks, pond margins, and meadows.
It is an annual herb growing a mostly erect, branching stem to exceed 30 centimeters in height. The oppositely arranged leaves vary in size and shape, from lance-shaped to oval, toothed or not, and under one to over three centimeters long. Flowers emerge from upper leaf axils. Each has a calyx of five narrow, linear sepals. The tubular corolla is up to a centimeter long, white in color with a blue or purple tint, and lipped at the mouth, the lower lip with three rounded lobes. The fruit is a capsule containing yellow seeds.

Attached images may be Lindernia sp. Please ID the plant  
Date :09.07.2015
Location: Assam
Family : Scrophulariaceae
Genus & species : ??
Habitat: Grows wild wild on flower tub 
Habit : Herb, basal leaf larger than top.
Flower : Small, white

Lindernia species in eFloraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ Biotik/ efloras/ books etc., where ever available on net) 

This plant looks like typical Lindernia dubia (L.) Pennell. (few varieties are also recognised)

Morphologically this species is closely similar to Lindernia procumbens (Krock.) Philcox, but differs mainly in the reduction of lower stamens into staminodes.

Thank You very much … for ID.

Lindernia species in efi so far with keys

Two closely looking species are 1) Vandellia erecta Benth. and 2) Ilysanthes parviflora Benth.

Both can have white flowers; pedicels twice the length of sepals.
Vandellia erecta Benth. has obtuse sepals & ovoid-orbicular capsules.
Ilysanthes parviflora Benth. has usually entire leaves; oblong-acute capsule.
Please check 1) FBI, 2) Bot. Bi. Or., 3) http://www.slideshare.net/heidenjoy/thesis-lindernia
I think this plant is Lindernia parviflora (Roxb.) Haines.
Appears close to images at Lindernia hyssopoides

I think matches much better with images at Lindernia dubia (L.) Pennell rather than those at Lindernia hyssopoides

this is scrophulariaceae and i wl go with Lindernia and not sure about species

Lindernia parviflora

It looks close to Lindernia hyssopioides. Or it may be L. manilaliana, as suggested by … at this link: efi thread
Thanks … for sharing the paper.

I think closer to images at Lindernia dubia (L.) Pennell

Lindernia hyssopoides ??

I think looks different from Lindernia hyssopoides (L.) Haines in markings on the flowers.

I think more closer to Lindernia dubia (L.) Pennell as per comparative images at ‎Lindernia
