Talk:Populus tremula

German and English Wikis inconsistent about the leaf dimorphism.

In German Wikipedia (de:Pappeln) it is written that this figure shows the early spring (left) and summer (right) leaves rather than the adult and juvenile leafs: links die in den Winterknospen vorgebildeten, rechts die Sommerblätter. No idea who is right but I would like to pay attention to this inconsistency. I need to discuss here as my written German may not be adequate. In any case, a reference would be good.

Yes, I noticed this inconsistency, too. I guess the English Wikipedia is right. I'm no expert, but an aspen just fell on my phone line here in Italy (...) and I noticed that the small juveniles nearby had these different leaves. Sorry, no better reference.. ;-) Greetings, 79.23.205.193 (talk) 09:03, 23 September 2013 (UTC)[reply]

Yes, the English version is closer to the truth, but there is something else. I have closely observed the leaf development of Populus tremula trees in what appears to be a clonal colony near my town. Thoroughly. The deltoid type of leaf in the right is produced basically by vigorous stump sprouts. It should be noted as variation. These leaves are quite big (as one could expect) and even have transparent pubescence on the lower surface.--Utar Sigmal (talk) 16:26, 25 September 2014 (UTC)[reply]

Is this not a confusion/misidentification with other poplar tree leaves? Rosser Gruffydd 09:33, 16 June 2015 (UTC)

I have a reference that is coherent with both Utar Sigmal and the Italian contributor. The stump has a character similar to young trees.--Auró (talk) 21:19, 16 September 2015 (UTC)[reply]

I will proceed to remove the caution notice.--Auró (talk) 21:35, 17 September 2015 (UTC)[reply]

I'm sure this removal was correct. Stace (2010:314) says "leaves suborbicular, coarsely and bluntly sinuate-dentate ... sucker-leaves ovate-cordate",^[1] precisely as in the image. Peter coxhead (talk) 08:36, 18 September 2015 (UTC)[reply]
