Your plant is a hybrid between A. natans and some other Apono, possibly
crispus. Natans has been introduced to many aquarium hybrids because it is
a very vigorous species, even if it is not as attractive as those species
that have fully submerged leaves. It is _possible_ that if you snip the
floating leaves, the plant will continue to grow submerged leaves. But as
with other hybrids, results are variable. You may have gotten one that
resembles its A. natans ancestors more than others.

Now you know what Neil Frank was talking about a few weeks ago in his post
about the different stages an aquatic gardener goes through. It sounds
like you've got the "growing plants" down pat. Now you need to learn to
manage the growth. While it is true that plants in an underlit tank will
"reach" for the light, the growth will be spindly and unattractive. From
what you've said, that does not seem to be the case in your tank. It
certainly shouldn't be with 4w/g!
The stem plants will always need to be trimmed, that's just the way they
grow. The best way to trim them is to cut back the stems just above a
branch 1/3 -1/2 of the way to the top. Don't cut too many at once, or your
plant will look like is got a crew-cut! The plant should branch and become
fuller with this type of trimming. If you must limit the growth of big
rosette plants (like Echinodorus) you might want to try decreasing the
amount of light and CO2 available to the plants. If your lighting
arrangement precludes the possibility of removing a bulb, you can reduce
the photoperiod instead.
