Here are also some historical pictures of the tree, if you are interested:http://www.wien.gv.at/umweltgut/public/identifyNaturdenkmal.aspx?id=ND_P.4787&mid=24f32749-7852-4ae8-bc5c-27bbc31fcdce&ftype=vienna:UMWELT.ND_P&g=e5ef1ea7-24f9-423e-9115-6a4b5bd462c7&cid=99df1080-8023-4cbc-8645-9e2776ffdb39
Tim will change it when he checks the discussion next time he logs on.
Tim Bekaert, the webmaster, can change the species now the determination is sure according to the article. So you can ask him.
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?
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.
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?
P.S. Excuse me for the bad Englisch.
1. The tree is, sadly, dead.
2. It was (as I'd suspected from the bark in this photo) Populus × canadensis, not Populus nigra.
