Big Joe ist tot!

Der Umfangstärkste Einstämmige Baum von Wien ist tot!!

Er wurde in einer Nacht-und-Nebel-Aktion mittels Seilzügen umgerissen und brach dadurch am hohlen Stamm, der jetzt Drei Meter hoch quer über einen ´Waldweg liegt...

Wieder haben die Prater-Verschönerer zugeschlagen

What is the explanation of this strange policy? This tree does not seems to grow along a busy road, so it was not dangerous at all!

I really dont know, how the brain of that people is working. There is only a small footpath, which is now closed.

What is your evidence that it was pulled down with cables, and not just fallen naturally? Pulling down with cables would need heavy machinery (a large tractor or similar), which would leave wheel ruts and other signs in the path. I can't see anything in the photos to prove this.

They had pointed BJ as risk tree 3 month ago and I found marks of cables or chains around the tree


Platanus orientalis digitata

Hallo Jeroen,

Ik was vandaag op Mariënwaerdt. De boom Morgenländische Platane (Platanus orientalis) '3498' is volgens het regiater van de Bomenstichting een digitata. Jij hebt foto's van het blad geplaatst. Dat lijkt mij inderdaad digitata. Wat denk jij?

Groet Wim Brinkerink


Jeroen Philippona, am 2015-03-17 21:56:11, hat gesagt:
Hoi Wim,

Ik zag deze boom ook als een 'Digitata' maar ik meen dat Leo Goudzwaard het daar niet mee eens was. Dus graag een reactie van Leo!

Groeten, Jeroen


Leo Goudzwaard, am 2015-03-18 10:00:43, hat gesagt:
de boom van Marienwaerdt is een echte P. orientalis. De cultivar Digitata heeft dieper ingesneden bladeren met weinig zaagtanden, het blad lijkt op de vingers van een hand.

groet, Leo

Hi Leo,

Verwarrend die bomenwereld. Martin Tijdgat heeft bij mij ooit de digitata geïntroduceerd. Ik besef dat het door Jeroen gefotografeerde blad niet erg digitata is. Maar...Ik vind het ook geen normale orientalis. (of ben ik erg abuis??) Ik heb met Nardo Kaandorp wel eens wat gesprekken gehad over wanneer er sprake is van een orientalis of een x hispanica. Verwarrende gesprekken. En nu deze boom. Ik weet niet wat en wie "Bosgroep Gelderland is", maar deze club meende destijds bij de Bomenstichting, kennelijk dat hier sprake is van digitata. Vandaar mijn prikkeling tot aandacht voor deze variant. Er is kennelijk geen spoortje twijfel bij je. Prima. Ik respecteer uiteraard jouw expertise.

Groet

WIm

Agree with Leo. Additionally, 'Digitata' was only first raised in about 1840, long after this tree was planted.

Hoi Wim en Leo,

Het grappige is dat dezelfde foto van deze boom in Leo's loofbomenboek op p. 239 staat als gewone orientalis met eronder een foto van een 'Digitata'. In de ANWB gids p 280-281 staat ook een duidelijke 'Digitata'.

Een duidelijke foto van een gewone orientalis staat op: arboretum . Een zeer oude boom, geen cultivar. Je ziet daar nog wat dieper ingesneden bladeren dan bij de boom van Marienwaard, maar net als daar met duidelijke zaagtanden, die op de 'Digitata' bladeren ontbreken, zoals Leo ook al aangeeft.

Groeten, Jeroen

Picea sitchensis - though the cones do show some resemblance to Picea × lutzii (hybrid between P. sitchensis and P. glauca); perhaps a backcross / intergrade from one of the natural hybrid populations in Alaska.
wwhiteside97, am 2015-03-17 10:22:32, hat gesagt:
Possibly could be Picea x lutzii then because the cones do not feel the same as Sitka spruce, they don't feel as papery.
Conifers, am 2015-03-17 10:34:32, hat gesagt:
Problem is, the leaves are typical P. sitchensis; on P. × lutzii they are shorter and denser.

The other possibility is the hybrid between P. sitchensis and P. engelmannii, which also occurs naturally where their ranges meet in Canada and SE Alaska, but hasn't been formally named; the leaves are within the variation of that.

wwhiteside97, am 2015-03-18 16:57:19, hat gesagt:
Have compared these cones to P. sitchensis and they are definitely different, I could upload a picture of these side by side if that would help? Although the leaves of the Sitka spruce which I gathered the cones from are definitely smaller than this spruce...
Conifers, am 2015-03-18 20:52:59, hat gesagt:
I've got some very similar cones to these in my study collection (and hundreds of 'normal' Sitka cones ;-) - the problem is, the ones like these are of unknown cultivated origin, which makes their identity, like these, somewhat speculative until they can be matched with known wild origin specimens.

Conifers, am 2015-03-14 22:22:17, hat gesagt:
That's sad. Any cones at the top that you could collect?
wwhiteside97, am 2015-03-14 22:30:56, hat gesagt:
Hi, yes there are plenty, I'm going to collect some tomorrow.
Conifers, am 2015-03-14 22:47:24, hat gesagt:
Probably mostly empty of seed now, unfortunately. I'd be interested to know the length of the longest you can find (and might like it sent to me for my study collection, please!).
wwhiteside97, am 2015-03-14 22:50:41, hat gesagt:
Thankfully seen a few that still had some seed in them. I'll have a good look round for the largest cones for you.
Conifers, am 2015-03-14 23:10:12, hat gesagt:
Many thanks!

Historytrekker, am 2015-03-11 13:56:35, hat gesagt:
Hi. Not 100% on my ID, so if anybody can assist with further ID please notify, & I will change details.

Height was 'estimated' by measuring up the tree 10ft with a tape to a recognisable point, then walking 50m back from the tree, using a stick to at arms length to duplicate the 10ft H, then using it to step up the tree.

Conifers, am 2015-03-11 22:21:00, hat gesagt:
Yes, Monterey Cypress is correct

patricia, am 2015-02-20 19:54:57, hat gesagt:
Lovely! Is this also known as a copper beech?
Conifers, am 2015-02-20 22:31:15, hat gesagt:
Yes
Frank Gyssling, am 2015-02-21 09:39:24, hat gesagt:
Thank you to mach, these copper-beech stands directly on the large fountain of the famous' Sanssouci Palace.

Conifers, am 2015-02-20 09:57:25, hat gesagt:
Do you have a close-up photo of the foliage, please?

Seems a highly unusual location for someone to plant a rare hybrid. Are you certain it isn't just Abies alba?

Milimims, am 2015-02-20 15:13:15, hat gesagt:
I don't have photo of the foliage, but i'm not sure that an hybrid.

it's possible that just an abies alba. I do the modification.

thank you for the warning that I should be best.


wwhiteside97, am 2015-01-18 15:35:52, hat gesagt:
Name tag says C. Lawsoniana cv. Versicolor... Would this be right? Definitely not the normal type.
Martin Tijdgat, am 2015-01-19 23:21:17, hat gesagt:
It is a named cultivar. Declared in 1888 by a Dutch nursery. Shall try to send you a description by mail.
WiPe, am 2015-01-20 17:10:41, hat gesagt:
Pyramidal and broad; branches spreading; branchlets spreading, decurving; sprays and leaves green spotted with creamy white or bright yellow. (Den Ouden / Boom;Manual of cultivated Conifers; 1965,Martinus Nijhof, The Hague)

I have seen one before, but this creamy white or bright yellow spots does not seem to be as bright as you might expect by this discription. I will try to add an image on monumental trees later this week.

wwhiteside97, am 2015-01-20 21:38:32, hat gesagt:
Thanks, would be appreciated.
Martin Tijdgat, am 2015-01-20 23:22:13, hat gesagt:
WW,

WiPe did it already. Thanks for that WiPe! Hope this will help. I also tried to find a good picture, but it is hard to find with this very old cultivar. Maybe WiPe can help you with his picture. Greetings, Martin

Conifers, am 2015-01-21 00:01:45, hat gesagt:
As an aside, whatever the cultivar, the species is Lawson's Cypress; it doesn't need to stay in the "Tree of undetermined species" section ;-)
wwhiteside97, am 2015-01-21 07:23:58, hat gesagt:
Ok thanks, will change it to Lawson Cypress later today.

Leo Goudzwaard, am 2015-01-02 08:08:21, hat gesagt:
var caesia is not an accepted name, the right name should be var glauca

TheTreeRegisterOwenJohnson, am 2015-01-02 22:44:59, hat gesagt:
It depends who you ask... If you ask me, I would suggest that it is probably best where possible if we all use the names as they appear on this site, rather than changing them frequently according to individual viewpoints.

Conifers, am 2015-01-03 00:32:41, hat gesagt:
Whatever the status, it is certainly has an incorrect spelling here; scientific names never use accents (á, é, etc).

As to the identity of var. caesia; it does represent a genetically distinct population, north of 44°N in the interior USA and Canada, with var. glauca south of 44°N. These two together are even more distinct from coastal menziesii, from which they are better distinguished at subspecies rank - see the discussion in Grimshaw & Bayton, New Trees.

There is an eastern hemlock in Spednic lake provincial park in New Brunswick in Southern York County near the canada US border. The span of my arms could only reach about a third around the circumference of the tree at five feet up from the base. It is a single trunk for several feet up the tree.


Conifers, am 2014-12-26 09:37:38, hat gesagt:
Nice find! Well worth getting a six metre tape and measuring its girth accurately.
