Yes, we got a permit from the DNR for keeping fish which also covered plants.
They gave us just the fishing reg's to go by for legal species.

I sat down with Baensch & Riehls aquarium atlas & studied the plants &
pictureds carefully.  I think now that I have, along with the Ceratophyllum
demersum (hornwort) species, I may have also got some Brazilian Milfoil 
(Myriophyllum aquaticum), Green Cabomba (Cabomba Carolinia) and maybe some
Potamogeton gayii.  I will try to find that book for better identification.

But the hornwort looked great.  The possible Potamogton gayii had some yellow-
ness but otherwise looked good, as did the possible Myriophyllum aquaticum.
Only the elodea looked bad.

The hygrophila, hornwort & lawn-like plant mentioned above were all store-
bought plants.  This is the first time I'v ever attempted to use native plants.

I think it is Uticularia gibba ssp. exoleta according to B&R's atlas.  It was
given to me & I think that I was told it was crystalwort but I don't think
it is crystalwort.

I'm not sure if the above comments apply to the plants in my other tanks
since they were all commercially grown (in Florida I think).  Do commercial
aquarium plants undergo seasonal effects?  I have noticed that my tanks have
gone through some periods where certain plants are predominant, but I had
thought it was due to a combination of pH, lighting & nutrient levels. 
E.g, when I had my 125 gal tank with UGF & put in new light bulbs last
Christmas & had lowering nitrates (20ppm-->0) & lowering pH (7.6-->7.0) over
about a six month period my Ludwigia replens really took off but my anubias
nana gradually disintegrated.  However, Ludwigia cuttings which I put into
other tanks with less light & without UGF's didn't do well.  In those tanks 
the hygro was predominant.  When the light bulbs were about 6 months old in
the 125 the hygro took over in there also.  Do other people notice cycles like


P.S.  How can I find out if my membership/subscription for the Aquatic
Gardeners Assoc. has expired?  I have not received the Jul-Aug 1995 issue
