    I've found it in several lakes in Marin County.


    Belem is a different biotype.


    I think whomever suggest it's parvula or straight obviously has never had it.


    It strongly curves downward and really never makes it more than 3-4 cm tall

    There were quite a few creeks and streams in SF back in the day. Many are diverted via piping now. There are still tons of springs that pop up all over the place. We have a diverted creek in our backyard. It has actually been piped. I'll have to keep an eye out for some and snap some pictures.

    And here's the pot of Tropica's tissue cultured E. 'Mini', via a dealer in Portugal:





    Divided and planted in a ten gallon tank with high light and CO2.

    Nice! Thank you for the picture, and thanks to Tom for providing the original culture to Tropica. "Sp. Mini" is really one of my favorite low-maintenance foreground plants.


    I have some of the original stuff that Aqua Forest Aquarium imported (5-6+ years ago) growing in my 60P. Got my starter clump from members of the San Francisco Bay Area Aquatic Plant Society. It's harder to get in the US since Tropica doesn't sell here. That said, I think more hobbyists grow the plant now than in the past, so that is a good thing. My emersed tank was started from some stuff AFA imported last year (2014)., marketed as "Eleocharis Sp. Japan."

    Don't know. This same species is also called Eleocharis Sp. Japan and Eleocharis Sp. Mini (Tropica). Belem probably refers to the location you mentioned. As for the origins, who knows!

    What's the best way to plant this? Does it come in that fiberglass mesh that most plants come in? If so, whats the best way to take it out of that without damaging the plant? Thinking of getting some on aquarium plants dot com.

    The "Belem" that I got came in a Tropica tissue culture cup, roots growing in a bit of agar that washed off easily in some warm water.


    There is a pic of that cup and the plants "up thread" a bit.

    For those still interested in the taxonomy of Eleocharis, here are some links.

    https://www.gbif.org/species/2716791
    https://www.ipni.org/n/30003459-2

    Kew recognizes 295 species in the genus. I'm pretty sure Eleocharis "belem" is just a name given to one of these valid/accepted species. Like Tom pointed out, E. belem doesn't grow like E. acicularis so we can probably exclude that species.
