Ludwigia or PP

[smgwee]

Hi Apollo,

I have this query too as I have the Ludwigia Sp Cuba before I bought the Ludwigia inclinata var Cuba during Aquarama.

When the inclinata grow and moth into submerse leave, it looks exactly like the Ludwigia Sp Cuba in my tank, thus I wrote an email to Martin from Tropical to ask if the Ludwigia Sp Cuba has been classified as inclinata var Cuba, and his answer is yes. Thus Ludwigia sp Cuba = Ludwigia inclinata var Cuba

However till today I have no idea why Tropical has not updated their plant database as they are still using the old name and I think this has cause the confusion.

The reason why “sp” was used was the plant was an unidentify or unnamed species. So be assured that what Far East offer you is the same plant that you want if what they have is Ludwigia sp Cuba and not Ludwigia sp. pantanal.

There are only 3 types of plants in there...

Pellia endiviaefolia, Hemianthus callitrichoides and ludwigia sp cuba.

Pellia endiviaefolia, Hemianthus callitrichoides and ludwigia sp cuba.

Then what Far East have is the Ludwigia inclinata var Cuba.

Hi gchoo

Just as puzzled with smgwee here. Hv seen Ludwigia Sp before. But the plants that i posted seems to have broader leaves at its edge and more sparse between the leaves.

So hope to hear some experts shed some lights here.

Thanks

Hi,

The pic you attached is a Tropica tank. I spotted 3 types of plants:

- Ludwigia spec. "CUBA"
- Hemianthus callitrichoides
- Monosolenium tenerum ("Pellia")

Ludwigia spec "Cuba" has been renamed Ludwigia inclinata var. verticillata "Cuba" but it's not updated in the Tropica site. What they sell is still in emersed form.

Answer is found in Juggler's Imagestation gallery.

Hi Vitri

From my posted pic, can you tell point to me which is pp and Lud pls?

The way i see it is actually Proserpinaca palustris and not Ludwigia tht we are assuming!

Like i said.. Lud hv sharp and pointed leaves and more compact unlike PP which is broader and less compact.

Thanks

Stephen

The pic you posted is not too clear due to the auto-resize of the forum, but those with the jagged leaves are PP, quite obvious in the top left. The colour and a few of the leaf shapes around the middle leads me to think that there are a few stems of Ludwigia Cuba mixed in. But you could be right that the whole bunch is PP. It doesn't help that the PP looks as though it's not completely transformed to submersed growth. If they were mature submersed plants, it's easy to tell them apart. It'll also be easier to ID if you can get a close up of that bunch of plants.

Pic from Aqua Botanic thread showing submersed form (left) and emersed form (right):


Also check out the following link. It shows good closeup pics of PP.
Proserpinaca palustris from Aqua Botanic Plant Database

So do you prefer the Lud or the PP? Both are really nice plants.

[gchoo]

Bro,

Sorry for the mistake... I took a closer look at the pic you posted again and it's indeed PP... I sure becoz of the following...

a) the arrangement of the leaves. Lud cuba does not have that arrangement.

Hi Guys

Think i found the answer. Its Ludwigia brevipes.

http://www.e-aquaria.com/n_brevipes.html

If am correct, anybody can spare me some for a token??

[hiromilizard]

hi Apollo

Jason here, it's not PP and also i think not brevipes,as i kept Lud brevipes before,... and PP

i just gave away a whole lot of brevepes... removed it as they grow way to fast .... brevipes grows something like arcuata.. they do not really have a crown .... in fact looks like broad leave arcuata..

jason
see ya on tues!

[apollo]

Hi Guys

Just got reply from Martin of Tropica. He says it L.Inclinata Cuba.

But the plant dont hv a crown like hiromilizard pointed out in the tank from Aquarama!

Am really lost.

So smgwee can u email me a pic of what you got?? Thanks

This picture is posted earlier by victri.

Apollo, what you saw might not had fully converted (I think the right word to use should be moth) into a submerse plant yet. Thus this might cause some confusion as most plants looks very different when planted emmersed.

If not mistaken, plants from Tropical are cultivated by mean of tissue culture, thus the plants are emersed and small, however with very healthy roots. Most tissue-cultured plants are acclimatized in before distribution.

If will to get this plant from Teo, it will look different as well, the plant from Teo is also emersed, however much larger stalk with thick stem. If you are getting from them, don’t tell them Ludwigia inclinata var Cuba, just tell them Cuba in mandarin and they will get it for you. I will try to post up the emesered form from Teo tonight.

Bottom line is, no matter who you get the plant from be it from Teo or Tropical, the plant will look like the picture posted by Victri after a few weeks.

For your information, most of the hobbyists here still call the plant Ludwigia sp Cuba

I think the both the Ludwigia inclinata var Cuba from Tropica and the Ludwigia sp. 'Cuba' from Teo is the same plant. Perharps Gchoo like to shed some light on this, since he collects rare plants from other countries.

When I first saw the Ludwigia inclinata var Cuba during Aquarama, it defintely looks like those I got from gchoo and Teo, perharps in different tank condition it grows slightly different.

Yes they are the same. I have both in my tank now and I can’t tell the difference which is from Tropical and which from Teo when they have both moth into the submerse form. (This has been confirmed by Martin from Tropical when I wrote to him 1 month after Aquarama, please see the first post of this thread)

thus I wrote an email to Martin from Tropical to ask if the Ludwigia Sp Cuba has been classified as inclinata var Cuba, and his answer is yes. Thus Ludwigia sp Cuba = Ludwigia inclinata var Cuba

Like I say in my earlier post, Tropical plant are smaller (tissue cultured plants are marketable even if the shoots are very young as the roots are well established) thus when 1 stalk of Teo emersed form is placed side by side with the Tropical plant, some hobbyists might think that it is a different plant. (Teo’s emersed Ludwigia has a thicker stem) However when they moth into submerse, it is the same if grown in the same tank.

Its the same plant for obvious reasons...
No comments on the plants exhibited or sold in Aquarama coz I did not go there mah... But probably becoz of the different climatic and substrate conditions that the emmersed plant is different... It could also be the way the emmersed plant have been derived...

[apollo]

I really think its L. Brevipes. Can anybody spare me some to kill my curiousity?

This is the Ludwigia inclinata var Cuba i got from Teo a couple of months back. Back then it was known as Ludwigia sp Cuba.

Doesn't look excatly like my emerse 'cuba' from tropica. Like Martin had mention on one of the reply. They may look different during the dry stage but the same at the wet stage.

That is why I thought it was a different when I saw it at the Aquarama, I bought this plant 2 weeks before Aquarama from Teo and back then this plant was known as Ludwigia sp Cuba.

The emersed plant from Tropical and Teo looked different but they moth into the same look in my tank!! At that time I was sooo confused as I thought it was a different.

I realized how interesting plants could be when Martin told I that Ludwigia sp Cuba has been identified as Ludwigia inclinata var Cuba.
