Can anyone identify the oak species these acorns come from?

Here are some pics of the leaves and bark

  • Your profile says you're in Ireland. Were these acorns also found in Ireland? Anything else you can tell us about the tree they came from or where it was growing?

  • Yeah this was in Ireland in the Phoenix Park. I did have a leaf but my daughter threw it away. Was just thinking of planting them really to see if they will grow Oct 9 '16 at 17:28
  • From what I remember of the leaf it had finger-shaped leaves if you know what I mean. Oct 9 '16 at 17:31
  • @conorgriffin please see updated answer

  • Thanks, next time I'm at the park I'll get some leaves and maybe update the question but it sounds like you're right Oct 10 '16 at 16:53

There are only a limited number of Oaks which produce this mossy cap at the bottom of the acorn - those that do are listed below, but without leaves, it's next to impossible to be certain which it might be:-

Quercus suber, maybe, the Cork Oak;

Or Quercus cerris (Turkey Oak, known as European Turkey Oak in countries outside of Europe);

And possibly Quercus hispanica 'Lucombeana' - can't find an accessible online image of this one's acorns, though there is one in my tree directory. Roger's Trees and Shrubs has a good picture, but their site is down currently.

Of these, Turkey Oak is widespread in the UK and Eire, and is the most likely candidate.

UPDATE - The images you've added, particularly of the grey, fissured/ridged bark, confirm the ID as Quercus cerris (Turkey Oak).


My guess without the leaves or bark would be Quercus robur; the English Oak or the Common Oak or the pendunculate oak.Quercus robur

    Nope. The caps of q. robur are not fuzzy like these.

  • From what I've seen, yes they are. Did you look at the pictures I sent? Hey, I am quite often wrong!!

  • Sigh, I think Bamboo's Turkey oak is closest. Maybe I was looking at a hybrid but of course can't find those pictures. Oh I love being wrong. Keeps me brutally humble.

  • I spent half my childhood in the branches of a q. r. - three trees in my parents' garden and lots in the forest nearby. And the acorns make excellent playing / crafting material. The caps don't have those "tendrils".

  • Yeah, yeah, I've already conceded I was wrong, again...you don't have to convince me any further! Grins! This is such a great way to keep our knowledge up to date and correct, huh!
