Danielc03, thank you, I've overlooked that!
Bacopa sp. "Paranai Guaz˙", "Bacopita"... it looks in the pics like the "Montecarlo" stuff...

"Monte Carlo" is a city in Misiones, Argentina, where some people discovered and introduced this plant in the Asian market. Here it is called "Bacopita parana i guazu" which is the name given by "TacuarendÝ". However, we now know that is not really a Bacopa. Also, you can take a look at it in my aquarium.

The emersed "Parana-i Guazu" from Juan/galettojm seems to have longer pedicels than Vadim's "Montecarlo": http://i159.photobucket.com/albums/t...acuario037.jpg
https://www.aquaticplantcentral.com/f...tml#post438844
- possibly matching the description of Micranthemum tweediei in the Marchesi 1997 paper (http://www.google.de/url?sa=t&rct=j&...w_wMY3jUfQYhjQ).

Are there slight differences between the "New Large Pearl Grass" collected by Japanese near Montecarlo and the strain that's called "Bacopita Parana-i Guazu"? Or is the different pedicel length rather a matter of culture conditions, or also of the age of the individual flower?

@Danielc03: You may possibly find flowering Micranthemum tweediei in your region that fits Marchesi's description: leaves elliptic, pedicels = flower stalks 3-5 mm long (as well as M. umbrosum with nearly sessile flowers and round leaves). It may be interesting to compare such definite M. tweediei with the aquarium plant.

I'm unfortunately more than 1000 km of the locations where plant thrives. I can provide pictures of my culture emerged that certainly have the same origin as Juan Castagnino plants, for if it is useful.

Thank you! Have you already seen flowers on them?

The species M. tweediei (as mentioned, I think it's not sure that the cultivated "Bacopita" Micranthemum belongs to that species) is apparently widespread in Argentina, possibly also in the vicinity of Buenos Aires:
http://www.tropicos.org/Name/29206570?tab=distribution
but I don't find infos about exact localities except Iguaz˙: http://www.tropicos.org/Name/29206570?tab=specimens

Enlargeable photo of the type specimen of Micranthemum tweediei in the Kew Herbarium, collected in Uruguay:
http://apps.kew.org/herbcat/getImage...ode=K000533491
http://www.kew.org/herbcatimg/227907.jpg
=> the leaves look more elongate than in the cultivated "Bacopita". Pedicels remarkably long, compared to the leaves.

Apparently the Bacopita is meant with "Callitriche sp." in the species lists of AGA contest scapes of participants from South America, examples:
