I'm looking for a plant I used to have over 30 years ago. It was a semi-floating plant, no roots and the leaves looked something like the leaf of the Water Weed but as I mentioned there weren't any roots as such. Also it grew extremely well in very poor light conditions and temp. really didn't seem to bother it one way or the other.

Thanks in advance

Jim

Jim,

Unfortunately, your description doesn't help me much, although someone
else might know what you are talking about. Some of the common plants
without roots include:

Ceratophyllum demersum (Hornwort or Coontail)
Azolla (floating fern)
Salvinia (floating fern)
Riccia fluitans (floating liverwort, crystalwort-not necessarily easy)
Ceratopteris (water sprite-has roots, but floats)

Try looking these up at http://www.tropica.com or
http://www.thekrib.com/Plants/Plants/ to see if you can find what you
are looking for.

I had no clue what he might be talking about, but now that you mention
it...maybe it is hornwort. He said "semi-floating," and hornwort is the only
common plant I know of that's semi-floating. Most either float or don't. g

OTOH, hornwort doesn't generally do well in very warm water, so temperature
does bother it.
