    I don't know for sure that this is evergreen, but all the leaves are still green, so it would seem to be so. It really stands out on the north side of Collingwood Park. I'm interested to know if it's a particularly large tree for what it is.

    Pedunculate Oak Quercus robur. Note the leaves with auricles at the base and very short petioles, and the acorns on long peduncles (see cup at top right of last photo). Deciduous, but late leaf fall. The specimen in the photo is medium-small size; it can get much larger.

    One planted during 1914 at the agricultural experiment station near Sydney on Vancouver Island measured 98' x 15'3" x 104' during 1988. By 1996 it had been killed by the installation of a water line near it. However, another regional example in the same size class remains at Olympia, WA. For a picture see

    Thanks, Michael and Ron. I thought I knew English oaks, but not well enough yet, knew nothing about the auricles and long acorn peduncles. Now I have to go back and learn pedicel/peduncle again. I thought I knew that on cherry inflorescences.

    Ron, I'm very happy to have that link to Jacobson's trees of the Washington state capitol campus. That's a beautiful tree.

    One of the most famous Quercus robur lives in Poland. It's nickname is Bartek, see http://www.kurowski.pl/pl/katalog.php?action=lisciaste&roslina=1462&nazwy=1 and http://www.panoramio.com/photo/33248535. According to the most up to date info it is 650–670 years old. It measures 13.5 meters in girth at its base, with crown spreading 40 meters. It is considered as a monument of nature.

    The thickest is amazing Pedunculate oak Kvilleken in Sweden http://www.monumentaltrees.com/en/swe/kalmar/vimmerby/945_kvilleken/. Next comes equally magnificent Bowthorpe Oak in the UK http://www.monumentaltrees.com/en/gbr/england/lincolnshire/2287_farminmanthorpe/. Next . . .

    They should be worshiped.

    I know this tree at Collingwood park and there's also another very nice one on the other side of the park near the washrooms in a resident's back yard.
