I was working in the tank again the other night and got some more shots of the Echinodorus palaefolius plant. Here is a view down into the tank.

This plant has grown really big. Its top sticks way out of the tank. i pulled it out in order to get a full-specimen shot. The chain link provides a sense of scale.

That flower stalk has been growing for more than a month with new blooms every day--you can see it off to the left. I don't have the whole thing in the frame, but it is more than 5 feet long.

Here is one of the little plantlets that has developed from the small groups of flower buds.

And here is a bloom.

Mire Monster helped me with the species determination for this one. I had it as E. cordifolius before.

The other sword in this display started flowering a few days ago. Here are a couple of pictures.

Does anybody have an idea of which species/variety this might be? Somehow this one never got labelled. It is much smaller than that E. palaefolius that is also in this tank and it has rounded, bright green leaves on long petioles. Note also the difference in flower shape.

I hope that Mire Monster will see this post. He might be able to offer a suggestion.

I moved some stuff around in here today. Here is a shot with numbers for all of the plants in hanging planters on the rear pane.

Echinodorus 'Ozelot'
Bacopa monnieri
Echinodorus 'Tropica Marble Queen'
Colocasia fallax 'Silver Dollar'
?? an unknown Echinodorus
Acorus gramineus 'Ogon'

I had removed the really big sword that was in there: it grew too large. I needed to get more background plants and decided to try to introduce a few different new Echinodorus and other things.

Does anybody know the species for the flower in the post immediately preceding this one. That plant is #6 in the picture above.

Miremonster graciously considered my questions and had a look at my pictures two posts back. Here is one of those shots again.

Here is a quote from his PM response.

If the inflorescence is arching to decumbent (laying down) and the pedicels (flower stalks) are quite long (up to 5 cm or more) , it is surely Echinodorus cordifolius (in the broader sense, incl. E. fluitans, E. ovalis, E. schlueteri, E. "aschersonianus"). E. grandiflorus group has upright inflorescences and coarse, leathery leaves with round petioles. E. uruguayensis group has ascending to upright inflorescences with few (ca. 3-5) whorls without branches, the leaf rosettes are low in emersed conditions.
Do You have closer photos of the leaves and petioles and the whole plant?

In Echinodorus from the trade it is often not sure if they are still true wild types or hybrids.

A new paper about species delimitation within Echinodorus (without chain swords = Helanthium):

Wow, great stuff.

today i got a better picture of the whole plant from the base of the crown to the top of the inflorescence it is about 24" (60cm) tall.

With some more description of the whole plant in my PM response, Miremonster arrived at the following additional conclusions.

Most forms of E. cordifolius get large (like E. palaefolius).

There is a form offered as E. cordifolius 'Mini' by Dennerle (Germany). I realized it is the same stuff like that described as E. schlueteri by Karel Rataj (Sumperk, Czechia). Dr. Jozef Somogyi (Bratislava, Slovakia) found out that Rataj's true E. schlueteri is not the same like the E. "schlueteri" from the trade. Somogyi described the latter as E. maculatus. Both E. maculatus and true E. schlueteri (=E. cordifolius 'Mini') are rather small to medium sized also in emersed condition.

I recently put together a blog post with some updates about this tank you can view it right here. I have allowed the aquascape in this tank to decline somewhat, but I have some pretty nice plants in here.

Here is a shot through the top of the tank, with numbering for certain certain plants of interest.

1. Spiranthes cernua var. odorata This is a plant that I acquired some time ago. It seems to be doing well, with new leaf growth and healthy root development. Only the bottom 1/3 of the planter is below the water's surface. This is a wetland plant, but I decided to err on the side of giving the roots a somewhat more aerated environment. Water wicks up from the bottom of the planter, so the planter media is wet all of the time. I shot the picture below on the day that I acquired this plant. It is quite a bit larger now.

3. Phragmipedium 'St. Ouen' - This orchid plant has struggled, but it is growing slowly. The picture below shows new root development inside of its planter. Most Phragmipedium species grow in moist to wet habitats in nature, such as locations along waterfalls or mountain streams. However, I have found that this variety does not tolerate having its roots fully submerged in water. I originally situated this plant with most of its planter below water and as a consequence the roots began to rot. The media inside the planter is still quite wet, as water wicks from below, but I now have it hung such that only the bottom 1/2" of the planter is in the water.

8. Orontium aquaticum - This is an extremely cool plant that I acquired at the end of the winter. I had to cut away about 75% of its extensive root system to fit it in its planter. The whole plant declined and I thought at first that it would perish. However, it is a hardy plant and it slowly recovered. It has grown several new sets of leaves and many new roots. The leaves have a wonderful velvety texture and the flowers have a strange, exotic look. I hope that it will bloom for me someday in the display.

9. Echinodorus cordifolius - I have a couple of previous thread posts describing this plant. It is a winner. Here is an older shot of one its blooms.

10. Echinodorus cordifolius 'Tropica Marble Queen' - What a gorgeous plant! I understand that in immersed culture the white variegation on the leaves of 'Tropica Marble Queen' is much more subdued. Here it is well-defined, even though the plant is only receiving moderate light inside of the display.

This is the abridged version. Like I mentioned before more detail is visible on my blog.

your amazon sword are in spectacular condition. i really like your setup it. it does seem alot easier to put together that the paludariums. how did you manage to grow your amazon sword emerse?

the way i grew mine was by sticking the little rootlets outside of the tank before they started growing the leaves.

i was wondering if there are any other way?

hydrophyte · 06-18-2009, 11:37 PM

Thanks very much! Oh my Amazon swords adapted readily to emersed culture. I have had trouble with most of the other swords that I have tried, many of which have refused to switch to emersed form leaves. I received the 'Marble Queen' as a small plant and it is just now gaining vigor and growing faster. I like it a lot. When it gets bigger I will use it as a centerpiece in this tank.

Yeah those little plantlets that develop on the flower stalks are great for propagating and great for getting the emersed-form plants if you can keep the leaves above water.

When trying to get Echinodorus to switch to emersed form I think that the most important thing is to slowly lower the air relative humidity. If kept in very moist air, the plants will "think" that they are still underwater.

Since the emersed plants are either just stuck to the glass with suction cups or floating these riparium setups are much easier to put together than most kinds of riparium designs--easier to tear down and maintain too. They also have more underwater space for fish because that area is not occupied by a large rockscape or foamscape or other built up structure.

I have been working on tidying this tank up some more. Here is a quick shot from tonight, the view down inside.

It will look real good when those various swords grow in just a little bit more. The underwater area is still pretty dingy. I want to work on resolving it so that I can get some more full-tank shots.

hydrophyte · 07-01-2009, 06:20 PM

And here is a shot of the whole thing.

As I explained, I need to fix the underwater area.

hydrophyte · 07-15-2009, 07:33 PM

Here is a quick update for this tank. I have put some effort into it and its looking better.
