On tropicos.org there's a botanical record of Micranthemum umbrosum that possibly has been collected in the same location:
Argentina, Misiones, Montecarlo, H.A. Keller, 28/11/1999
http://www.tropicos.org/Specimen/2232924

Also Echinodorus uruguayensis is recorded in Argentina, Misiones, Montecarlo (the name of a river?): Renvoize 20/10/1978
http://www.tropicos.org/Specimen/3388363

But I can't find any information in daigorou11's blog (http://pokoujiaz.exblog.jp/11591129/) that the location "Montecarlo-3" where he found the Micranthemum "New type" and E. uruguayensis [Type horemanii] is actually in Argentina, Misiones.

The trade name "New type Montecarlo-3" (Vadim's post) may point to the origin. Perhaps imoprted from South America via Japan (Rayon Vert or so), and listed and described in any Japanese catalogue?

p.s. @Vadim: Now I've found Your link, sorry
Currently growing them both in the same tank. M. umbrosum is not creeping and leaves are different.

As far as I've read, 2 Micranthemum species are distinguished in southern South America (incl. Argentina where the New Large Pearl Grass / Micranthemum sp. "Montecarlo-3" was found):

- Micranthemum umbrosum (widespread in the Americas): leaves roundish (orbicular), flower stalks (pedicels) almost wanting (virtually sessile flowers).
- Micranthemum tweediei, also written M. tweedii: leaves elliptic, pedicels 3-5 mm.

See that pdf: Marchesi 1997, Scrophulariaceae en El Uruguay. http://www.google.de/url?sa=t&rct=j&...w_wMY3jUfQYhjQ

I don't know pics of Micranthemum tweediei except those on jstor of herbarium specimens (I don't have access to the enlarged pics): http://plants.jstor.org/specimen/k000533491
Difficult to say if the leaves of the M. sp. "Montecarlo-3" are still orbicular or already elliptic. It has to be flowered to check the pedicel length.

Great!
The flowers look to me like Micranthemum ones at first glance. How long are the pedicels (flower stalks)? (see my last posting: pedicels 3-5 mm long => M. tweediei)
It would be good to preserve specimens and to send them to a specialist. Surely Cavan could give you advice.

OK, that speaks against Micranthemum tweediei. But the flowers are visibly stalked, not almost sessile, as in the case of M. umbrosum. =>

Btw., the M. "Montecarlo-3" is sold as "Elatine hydropiper": http://www.tropica.com/en/plants/pla...n.aspx?pid=025

No, it's misnamed. The company Anubias (Italy) has E. hydropiper that's likely correctly determined (at least it's an Elatine), it's very different to the Tropica one.
Drawing of E. hydropiper, the flowers and leaves show clear differences to the "New Large Pearl Grass": http://www.plantsystematics.org/imgs...iper_5590.html
