Hello everyone! A post on a new ground-cover plant is up on my blog AquaBiota! Here is an excerpt of what you'll find there, for the rest click on the link below! Thank you for taking the time to check out this post ☺ Enjoy!

The most defining characteristics of this plant is that the leaves (almost 1/2 inch max in diameter) are perfectly round circles that come out in pairs at each node along the stem. The lack of any petiole connecting the main stem to the leaf, makes for a very compact-look. When this plant is grown to its fullest it looks like a tight mat of circular leaves. At this time there really isn't any other ground-cover plant like it in the hobby.

Yes of I know a scientific name would be helpful, but being as it only somewhat recently discovered and was immediately introduced to the hobby here(mid-2011 to early 2012), there is no name as of yet, it will take some time. If I find something I shall update this thread. As for where it was collected, still working on that one also.

Ragn4rok and travis808- I really appreciate your kind words, means a lot and keeps me going! :)

I bought this plant as Micranthemum sp. New type Montecarlo-3. I think, maybe, it's not Micranthemum and Hemianthus. Interesting plant, grows well in the aquarium.

I got it as a Micranthemum sp. also but not totally sure what it is. Are you currently growing some emerged? Currently, I am trying to flower this plant. Give it some time, and we will figure out what it is. A very different and unique foreground plant.

Yes, very true! That is always the case for new plants! And trying to find out what it is, is all the fun!:D (Well kinda! LOL! I would rather just scape with them:biggrin:)

It looks in the photo like Micranthemum umbrosum to me. Difference in larger leaves and more creeping growth?
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

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.

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...s4HoBg&usg=AFQjCNERxhVlu_I58Orgw_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.
