Hi, Jeroen can also change the species of trees, so Jeroen, feel free to do so when there is consensus. I have now done it myself.

Kind regards,

Thanks! Yes, it has bark typical of true Populus nigra.

Hi Mr Green - on a similar line, do you have a larger size original of this photo, please? It is probably correctly named, but I would like to see the bark pattern better to be sure. Thanks!

You're welcome!

Tim will change it when he checks the discussion next time he logs on.

Hi Mr. Green,

Tim Bekaert, the webmaster, can change the species now the determination is sure according to the article. So you can ask him.

Hey Conifers,

thank you very much for this helpful explanation, i will take care of the difference in the future.

I can't change the specified from P. nigra to P x canadensis. Is there anything I should do about it? Maby contact someone to change it?

Hi Mr. Green,


Of the identity, I only suspected it was P. × canadensis before, I couldn't prove it. But the article says it has been proven now from genetic data. My evidence was the bark, which is deeply fissured with nearly parallel ridges (typical of P. × canadensis, like "||||"); in pure P. nigra, the bark is less deeply fissured, and the fissures are crossing, less parallel (like "XXXX") - the difference is easily visible by comparing with your photo of this tree which is typical of true P. nigra.

1. Yes that picture was taken after his death - I thougt I recorded that - sorry.

2. With all due respect - as far as I know, it is very hard to differentiate between the Hybrides and the genius in this case because it needs a biochemic-genetic proceed and consequently more than the knowlegde about the morphology. But I could be wrong, how did you determie that it is a Populus × canadensis?

best regards,

Mr. Green

P.S. Excuse me for the bad Englisch.

Found this article:

Two points:

1. The tree is, sadly, dead.

2. It was (as I'd suspected from the bark in this photo) Populus × canadensis, not Populus nigra.
