Please help id this small herb:
An uncommon plant Seen in outskirts of Chennai growing in fallow land,
Small plant  under 1 foot height ;
leaves are opposite and somewhat succulent,
individual flowers were 2 to 3 mm. pinkish coral in colour,
sessile ( or sub) along the stem.
Flowering in february

This is Ammannia baccifera of Lythraceae.
Tamil name: “Neer mel neruppu”

Does the baccifera also have a variety with greenish flowers?
Its also amazing that while it grows in marshy areas/ dry beds, it does well as an aquarium plant  !!
The Tamil name has is expressive, meaning “fire on water”, referring perhaps to the reddish flowers on a plant growing in the  marshes.
