Too many leaflets for Juglans regia, and the terminal leaflet is not larger than the others. I suspect this is one of the hybrid walnuts, perhaps between Juglans regia and Juglans nigra, or between Juglans regia and Juglans ailantifolia.
TheTreeRegisterOwenJohnson, am 2014-08-31 19:23:26, hat gesagt:
From the bark, I think it's J. x intermedia (nigra x regia). It's good to see such interesting rarities appearing on the site!

Wim Brinkerink, am 2014-08-30 11:18:49, hat gesagt:

Jij hebt deze boom gedetermineerd als Betula platyphylla. Als ik de schors bekijk ziet hij er meer uit als een ermanii. Dat komt ook overeen met de beschrijving die aan het begin van het gebied Japan is gegeven. Maar..ik ga hem niet zonder meer wijzigen zonder jouw mening.

Conifers, am 2014-08-31 13:53:32, hat gesagt:
I would agree with Betula platyphylla - the seed catkins (visible in the foliage photo) are slender and drooping, whereas on Betula ermannii they are stouter and erect.

TheTreeRegisterOwenJohnson, am 2014-08-31 19:20:02, hat gesagt:
I think Betula ermanii x pubescens. A lot of big 'Betula ermanii' in Britain are this hybrid - presumably open-pollinated seedlings raised in Europe. In this case, the bark of the trunk is nearly B. pubescens, that of the smaller branches close to B. ermanii. The leaf is close to B. ermanii (but should show hairs on the stalk and under the veins). Fruit will show intermediate features. Betula [pendula subsp.] mandshurica/B. platyphylla in my experience has long-pointed triangular leaves which are a very dark (not yellowish-) green and forms a slender, sometimes slightly weeping tree.

Conifers, am 2014-08-31 13:55:25, hat gesagt:
A pear Pyrus sp. Sorry, not sure which species.
TheTreeRegisterOwenJohnson, am 2014-08-31 19:14:21, hat gesagt:
I think Malus yunnanensis. The bark is right (peeling in big scales of grey and brown). The fruit should have little raised white dots (not visible in the picture) and the leaf should be densely hairy underneath.

TheTreeRegisterOwenJohnson, am 2014-08-21 18:43:17, hat gesagt:
What a magnificent tree!

I wonder (from the bark colour and apparent needle length) if it might be Pinus strobus instead? But I'm unfamiliar with the behaviour of either species in Germany and would welcome other opinions. In Britain, P. strobus never carries that many cones.

Rainer Lippert, am 2014-08-21 20:01:39, hat gesagt:
Hallo Owen,

ich habe noch zwei weitere Bilder hochgeladen, eines davon von einem Zapfen. Vielleicht hilft das weiter. Ich selbst habe mich auf das Schild am Stamm orientiert. Aber das muss ja nichts heißen, die sind ja auch öfters mal falsch.

Viele Grüße,


Conifers, am 2014-08-21 23:07:42, hat gesagt:
The cones confirm Owen is right, it is definitely Pinus strobus ;-)

PS Owen - I have seen Pinus strobus in Britain with heavy cone crops.

Rainer Lippert, am 2014-08-23 17:31:18, hat gesagt:
Hallo Conifers,

danke für die Bestätigung. Ich ändere es entsprechend ab. Aber auch so ist es der höchste Baum der Art in Deutschland/Europa.

Man sollte die Personen die immer diese falschen Schilder anbringen verklagen ;-)

Viele Grüße,

Hello Mairie,

this is a magnificent tree, but it is no Sequoiadendron giganteum. It's a Sequoia sempervirens. And if the girth measurement is indeed correct, it would even be the largest specimen here in Europe. It sure looks like a heavy trunk. Congratulations...:-0...!

Thanks for sharing...:-)

Best wishes


RedRob, am 2014-08-06 16:13:01, hat gesagt:
Agree totally with Frank, what a magnificent Coast Redwood, second tallest recorded in Europe at the moment. The photo with the people walking past really gives a context, a perspective of it's size. Well done for bringing this tree to light. What is the climate like In Vals-les-Bains, not familiar with this area so will Google at some point if no rely.
KoutaR, am 2014-08-07 10:36:18, hat gesagt:
Hello Mairie,

A magnificent tree, indeed. Which instrument did you use for the height measurement?


mairie07, am 2014-08-12 07:42:21, hat gesagt:
bonjour et merci pour vos commentaires et compliments.

Pour la mesure nous avons utilisé la méthode théodolite à visée laser et pour la circonférence un ruban souple apposé au tronc.

Nous sommes situés dans le Sud Est de la France en région Rhône-Alpes dans le département de l’Ardèche.



Conifers, am 2014-08-14 19:29:44, hat gesagt:
Still needs changing to Sequoia sempervirens - any objections to my doing so?
Jeroen Philippona, am 2014-08-14 20:28:59, geändert am 2014-08-14 20:40:39, hat gesagt:
Bonjour Mairie,

I hope you don't mind that I have changed the species from Sequoiadendron giganteum to Sequoia sempervirens, wich it very clearly is.

We like to have the right information on this website about species and measurements.

This specimen is extra interesting as indeed being probably the largest and second tallest Sequoia sempervirens tree in Europe we know of.

It seems to be a rival of the largest Seqoiadendron in Europe regarding to total woodvolume and could be one of the largest trees in Europe already.

Best regards,

Jeroen Philippona

Very nice tree !!

The measures was made by personnel of the Town Hall and 'mairie 07' says that they used a theodolite, a surveying instrument.

Site slowdown

Tim, am 2014-08-10 10:46:37, geändert am 2014-08-10 10:47:20, hat gesagt:

as you probably all noticed the site got slower to even unreachable the last days.

I found the cause and have a solution in mind that I will try to implement today. This should cause the site (especially the image overview pages) to be faster than before, but in the meantime the overview pages per country/province/municipality will not list any images. The image pages as such (not the overview pages) will remain accessible and you can continue to use the site without restrictions.

Just so you know these empty image overview pages are intentional and temporary.

Kind regards,


Tim, am 2014-08-10 14:44:28, hat gesagt:

everything should now be relatively fast again and working.

Kind regards,


Conifers, am 2014-08-14 19:33:13, hat gesagt:
Thanks Tim!

One other cause of slowdown - the flickering numbers on the home page (number of registered trees, etc.) slow loading down quite a lot. I have also read that flickering images like this can be dangerous for people with epilepsy (they can trigger an epileptic fit). Maybe make the numbers appear in the final totals from the start, without the 'counting up'?

Tim, am 2014-08-15 16:34:41, hat gesagt:
Hi Conifers,

I have to disappoint you but these moving counters don't slow down the site.

The actual numbers they stop on after moving are already known as soon as you see the page, and getting these numbers is much less than a fraction of a millisecond as it doesn't involve any actual counting. The moving numbers that you see then is just a simple animation that is done at the client's side to make that main page appear more dynamic (like see, the database is ever growing).

I made the color of the counters somewhat less black to soften the contrast.

Kind regards,

Beste luisindepels,

Ben het met de collega's eens; dit is geen Taxodium maar een Sequoiadendron. Verander je de naam zelf?

Groet, Martin

luisindepels, am 2014-08-15 11:52:13, hat gesagt:
ok jullie zijn meer experts dan mij...

Wim Brinkerink, am 2014-07-19 14:57:28, hat gesagt:
Hi Nardo,

Volgens mij heb jij deze bomen gepost. Volgens mijn informatie is het echter geen grondgebied van Schin op Geul maar van Valkenburg. Dat maak ik in ieder geval op uit Wikipedia en het staat ook aangegeven in deel zuid van de "Gids voor de Nederlandse tuin- en landschapsarchitectuur. " Ben je het eens en zoja vind je het goed dat ik het verander of wil dat zelf doen. Het lijkt me ook goed om het gebied van het kasteel wat preciezer te splitsen. De Thuja staat formeel op een deel van het kasteelpark, genoemd Sjloensheim. (Formeel adres; Oud Valkenburg 1)De molen en het heempark vormen één geheel en dat bestaat sinds 1950. Het wordt gerund door vrijwilligers van het IVN

Conifers, am 2014-07-19 21:45:27, hat gesagt:
Hi Nardo, Wim - on the subject of the Thuja, I am still pretty sure this is T. plicata, and not T. occidentalis as the sign says. Can either of you get some close-up photos of the foliage and cones for verification?

Wim Brinkerink, am 2014-07-20 08:22:53, hat gesagt:
Hi Conifers, I just uploaded the photo's of some details.

Martin Tijdgat, am 2014-07-20 09:27:17, hat gesagt:

Ben het met Conifers eens; dit is Thuja plicata.

Conifers, am 2014-07-20 12:39:06, hat gesagt:
Thanks! Yes, definitely Thuja plicata.

Wim Brinkerink, am 2014-07-20 12:39:16, hat gesagt:

Ik heb het adres van de tuin gevonden; dat is Oud Valkenburg 1, Schin op Geul. Dus jij hebt de boom op het juiste dorp geregistreerd. Nu moet alleen de soort nog gewijzigd worden.



Nardo Kaandorp, am 2014-08-14 06:35:56, hat gesagt:
Hallo Wim,

Ik lees dit verhaal nu pas (geen automatische mail ontvangen helaas). Het zal dan inderdaad wel een Thuja Plicata zijn. Wel jammer dan van het mooie verhaal op de site en het bord in de tuin. Dat klopt dus nu niet meer. Ik denk dat we deze personen op de hoogte moeten brengen.

Overigens de boom oogt wel vrij "geel" voor een Plicata. Kan het misschien een Plicata "Zebrina" zijn? Heb je nog een detailfoto van het loof?

Wim Brinkerink, am 2014-08-14 08:30:15, hat gesagt:
Hallo Nardo,

Ik heb de enige detailfoto van het loof die ik heb bij de boom geplaatst. Ik heb helaas een hoop foto's moeten weggooien, omdat een paar flinke instellingsfouten had gemaakt met mijn nieuwe camera. Helaas veel mooie foto's en detailfoto's kwijt geraakt. Ik neem aan dat Conifers en/of Martin indien nodig inhoudelijk op jouw opmerking reageren. Ik heb er niet zo veel verstand van.

Overigens was het bordje wel recent vernieuwd. Wellicht door de gemeente. Ik zal het toevoegen aan de boom.



Martin Tijdgat, am 2014-08-14 09:50:33, hat gesagt:
Nardo, Wim, Conifers,

This a bit yellow for Thuja plicata, but it is not cv. Zebrina. That is yellow and green stripped. Have a detailed picture from tree and twig of Th. pl. Zebrina from woodstock Gardens, Instioge, Ireland.


Conifers, am 2014-08-14 19:28:42, hat gesagt:
Agree, it is not 'Zebrina', which (like the animal it is named after) has striped variegation. The yellowing could easily be due to the soil conditions it is growing it. Shame about the new board, they will have to change it yet again when Wim tells them about its identity ;-)

A technical point: as these trees are seed-grown (self-sown), they are Fagus sylvatica f. tortuosa, and not the cultivar 'Suenteliensis', which to be true to name can only be propagated clonally by grafting.

Martin Tijdgat, am 2014-07-23 22:03:10, geändert am 2014-07-23 22:04:25, hat gesagt:

Thanks for this. You are absolutely right; this is the naturaly occuring forma tortuosa. I had the same type of discussion with Fagus sylvatica 'Asplenifolia'.or 'Laciniata'. This leafform also occurs naturaly and has been grafted under a few different names.

Maarten Windemuller, am 2014-07-23 22:17:54, geändert am 2014-07-24 08:50:18, hat gesagt:
Thanks, that's true, it's not a clone. I changed name. New problem: I cannot get a small "f" before tortuosa. The system automatically generates a capital F. Will ask Tim to change it. But what must we think about the oak, MT nr. 18706? :)

On 7 july Daily Mail published an article about the 'oldest' tree of Brittain.

I cannot (yet) find the tree on MT. Do I look good?

Conifers, am 2014-07-08 09:19:13, hat gesagt:
Don't believe anything you read in the Daily Fail - one of Britain's most notoriously inaccurate newspapers ;-)

Certainly an interesting tree, but 5,000 years is fanciful. It fails to take account of the simple point that growth rings become narrower as the tree ages.

For more info on the ages of old yews, see:

Harte, J. (1996). How old is that old yew? At the Edge 4: 1–9 Online.

Kinmonth, F. (2006). Ageing the yew – no core, no curve? International Dendrology Society Yearbook 2005: 41–46 Online.

Leo Goudzwaard, am 2014-07-08 09:25:27, hat gesagt:
Is there any scientific proof? an article rather than a newspaper story?

according to the newspaper it is believed to be 5000 years (ja zo lust ik er nog wel een!)

A ring count of 120 per inch is hard to believe. Where is the picture of this? BTW: ringdating and dendrochronology is something completely different than ring counting. Waiting for proof....

Maarten Windemuller, am 2014-07-08 09:49:39, hat gesagt:

Thank you for the reactions. This brings us further than Facebook where I found this 'news'.

Best wishes, Maarten

RedRob, am 2014-07-08 17:05:10, hat gesagt:
Maarten beat me to this with his post. This tree has been all over the news as well

Conifers, can you explain your point about growth rings becoming narrower not being taken into account?

Conifers, am 2014-07-08 18:00:37, hat gesagt:
Quote from the Daily Fail article: "and its ring count is 120 per inch which makes it [more than] 5,000 years old" - i.e., they've taken the outermost ring count and assumed it continued at that rate for the whole life of the tree. Typical muddle-headed journalists :-(
