A pear Pyrus sp. Sorry, not sure which species.
TheTreeRegisterOwenJohnson, at 2014-08-31 19:14:21, said:
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.

Hai Wim,

Do you have recent picture of its bloom? Ore a detailpicture of twigs with leafs? It looks like a Malus.

Hi Martin, In documentation of the municipality on this arboretum, it is stated that in in the month of may, you can see blooming ornamental apples, especially the Malus hupehensis. I think this is a hupehensus. I will post some recent pictures.

Dat was ook mijn eerste gedachte toen ik de boom zag. Maar het blad is zo vreemd voor een plataan. ????


Martin Tijdgat, at 2015-05-26 03:11:43, said:
Hai Nardo en Han,

Een plataan is het niet. Blad en schorsstructuur doen mij meer denken aan Corylus colurna. Maar daar ben ik niet zeker van. Zal eens kijken naar exemplaar in Oranjepark in Uithoorn of het klopt.

Groet, Martin

hallo allen,

het is een plataan, ws de gewone P. x hispanica


Leo Goudzwaard, at 2015-05-26 10:21:48, said:
het blad is net aan het uitlopen vandaar dat de vorm nog niet op een volwassen blad lijkt.

Nardo Kaandorp, at 2015-05-26 18:55:31, said:
Hoi Leo, jij zegt "waarschijnlijk" maar zou het toch misschien een Westerse plataan kunnen zijn? Het kan toeval zijn dat je op de foto een paar keer slechts 1 vruchtbolletje ziet hangen, maar bij een gewone plataan had ik minimaal 2 bolletjes aan 1 steel verwacht.

@Han, ik zag zowaar dat jij de eerste en enige Westerse plataan van Nederland hebt opgemeten in Zevenbergsche hoek. Wat was nu het grote verschil met de gewone plataan?


Leo Goudzwaard, at 2015-05-27 09:52:42, said:
hi Nardo en Han,

de 2 platanen zijn moeilijk van elkaar te onderscheiden. Onderscheid aan blad blijkt niet goed mogelijk.

Ook aan de vruchten is niet makkelijk, omdat P. occidentalis meestal 1 bolletje heeft en zelden 2. P. x hispanica heeft meestal 2, maar kan ook 1 bolletje hebben.


Nardo Kaandorp, at 2015-05-27 19:56:44, said:
Ok thanks! Eigenlijk hetzelfde verhaal als bij de Oosterse Plataan. Daar is de bladvorm ook niet 100% bepalend voor de soort. Dan is dit waarschijnlijk toch gewoon een hybride.

Han van Meegeren, at 2015-05-27 20:07:15, said:
Allen bedankt.

Mijn eerste suggestie was meteen een gewone plataan, maar die bladeren deden mij zeer twijfelen. weer iets geleerd. Determineren zal nooit mijn specialisatie worden, dat is wel duidelijk. :-)


Han van Meegeren, at 2015-05-27 20:11:03, said:

Ik heb die plataan meteen ook veranderd in Zevenbergschen hoek. Daar heb ik gewoon naast geklikt. Ik ken geen westerse platanen in Nederland.

Met wat speuren kwam ik een palm tegen die hier op lijkt: Borassus aethiopum. Maar een deteminatie is dit niet. Wellicht dat Hortus van Delft of Amsterdam kunnen helpen, of Diergaarde Blijdorp in Rotterdam. Daar zitten palmenspecialisten.

Aye RedRob,

If the tree in question is the 'hairy' one left of centre, then from the image I am guessing that it is most likely a Sitka spruce (Picea sitchensis) that has developed a vigorous mass of epicormic shoots. Whether this is due to an increase in side light striking the trunk since thinning operations or a genetic malfunction I cannot discern from the image. I also can't discern the cones from the image. Is it possible to obtain close up images of the bark, needles, shoots and cones, as this would ease diagnosis?

Regards, themoudie

Hello Moudie, welcome to the forum (haven't noticed your name previously) Hope that you don't mind my asking, are you in Scotland or living in Scotland?

A previous discussion about this it was thought that it was another Douglas Fir, it is the tree clothed to the ground just to left of centre. There is a large grove of c50 metre Sitka Spruce about 200 metres to the left of this photo. I was so busy looking at the emergent tree two to the right of this tree which the laser measured as c55 metres, I should have noted what this tree was? At first with the dense narrow habit thought that it might be a Picea Abies that I had missed, if so it would be 49/50 metres as the tree 4 tips to it's right, Douglas Fir was 49.8 metres. If you click in the photo and then when the little magnifying glass comes up click again you can enlarge the photo.

themoudie, at 2014-11-12 01:23:16, said:
Aye RedRob,

Thank you for your welcome, and yes to both of your questions about Scotland. I have used the magnifying facility, but it produces a very pixelated image for me that doesn't aid diagnosis. I was thinking that it might be Serbian spruce (Picea omorika), but the apical growth rate I wouldn't have expected to keep pace with Sitka spruce (Picea sitchensis) or Douglas fir (Pseudotsuga menziesii). Hence my request for some detail, if poss.

Good health.

My regards, themoudie

Hello Moudie

Are you involved with forestry or arboriculture? Are you in the Highlands or low lands? Whatever, you must live in striking distance of some magnificent trees of all descriptions.

I have added what photos I have of this tree at Dalby, I was so busy with the Douglas that I didn't go up to it. It was only when I later looked at the photos that it stuck out with it's very narrow habit with foliage to the base and quite heavy crop of cones whilst the surrounding Douglas appear to have none or very few. I should also have noted what the small blue conifer was, the track next to these trees is/was one of the best viewing areas for the old Lombard RAC Rally when it was held here years ago now.

themoudie, at 2014-11-14 21:39:13, said:
Aye RedRob,

Yes to both and Southern Highland boundary fault! ;¬) Aye, there are plenty to cuddle.

Thank you for posting the additional images of the trees in the vicinity of your first image. I can see why you are remarking upon the fully clothed tree and the shorter vigorous growing one with the blue green foliage. I suspect shelter, available nutrients and moisture along with the adjacency of the large trees are all contributing to it's form. It may even be the prodgeny of one of those older trees.

If I am fortunate to be in the vicinity of these trees I shall try to give them a look.

Any ideas what this one may be, not the ideal photo admitted from distance? Through the 6x finder scope in the laser it looked like Nordmann Firs that I have now had the pleasure to see in person. Any records of Nordmann Fir at Thoresby Hall Owen?

Sherwood Forest is such a legendary, atmospheric place but overall the stature in height of it's trees is abit disappointing, alot of young Pine forest and newly planted deciduous woodland.

TheTreeRegisterOwenJohnson, at 2015-05-22 17:39:59, said:
Hello Rob,

I suspect that this willow is the older clone 'Salamonii', which grows better in the north than 'Chrysocoma' does. The crown is less weeping and lacks the long hanging streamers of 'Chrysocoma'. However in a shorter growing-season a 'Chrysocoma' might fail to grow these long streamers so I'm not 100% certain. The critical difference is that the young twigs of 'Chrysocoma', at least where they get the sun on them, are quite a clear yellow (making the tree look blond in winter), while all the young twigs of 'Salamonii' are a dull grey-brown. I'm sure you can decide on this.

Owen

RedRob, at 2015-05-27 12:08:19, edited at 2015-05-27 12:09:03, said:
Hello Owen, from your description I would say definitely Chrysocoma. The trees did look yellowy blonde in winter, also, behind the stone wall is the garden of the owner of the end house on the left in whose garden the tree stands. The tree is regularly pruned underneath and on the sides where it hangs over the paths and grass and the road footpaths so the long streamers are cut back. The block of houses are south west of it so it just has that bit of shelter which has probably enabled it to grow to this size. Another Willow in the same garden is 17.4 metres.

The leaves are broad and many/most with an emarginate (notched) apex, so not T. heterophylla. A cone would help identify it, as would a sharply focussed close-up of the shoot showing presence or absence of pubescence.

The line of upside-down small leaves on top of the shoot is usually characteristic of T. canadensis.

@ Owen - yes, true; but notched leaf apex doesn't fit that. I'd not be surprised if it turned out to be a hybrid.

Thanks Martin, Conifers, Owen. I have not seen many if perhaps any but from photographs of other trees I thought Canadensis and identified it as so to Nikki (in the photo) but if it could be a hybrid? Any old recordings of Tsuga at Belvoir Owen?

Nikki is going to girth all the Belvoir trees featured when she gets around to it.

TheTreeRegisterOwenJohnson, at 2015-05-25 18:51:00, said:
With its rapid growth and ideal adaptation to the Scottish climate, Abies grandis is the first of the giant conifers from the American north-west to rival in cultivation the sizes it reaches in the wild. Measurements since 1956 suggest that this tree on the Murthly Castle estate was planted around 1880; it is no beauty but is now sheltered by other conifers almost as tall and continues to grow as fast as ever (with 50cm leaders in 2015), making it probably now the most massive tree in northern Europe. The trunk is partly obscured by the retained low branches but hardly seems to taper to the first fork at 24m.

Using the American points system to compare big trees, 301" girth, 187' height and 40' average spread give this tree 498 points. Compare 491 points for the largest known in the USA in 1988 (251' x 19' 1" x 43' by Duckabush Creek, Washington).

Conifers, at 2015-05-26 09:26:19, said:
The US 'points system' is very misleading as it gives great emphasis to open-grown trees with very wide branching. In height and girth, this tree is nowhere near as large as the old-growth native specimens which developed in natural forest habitats.

Empty photograph lists and "max_user_connections" issue
Visible for everyone · permalink · de
Tim, at 2015-05-19 14:22:53, said:
Hello,

most of you have encountered the "User monumentaltrees already has more than 'max_user_connections' active connections" issue lately and I have gotten quite a few mails about this.

I wanted to let you know that I am aware of this, and I am thinking of a solution. In the meantime, some image lists might not contain photographs. The photographs are not gone, they are just not listed for the moment.

Details for those interested:

The mean reason is that at any given moment only a limited number of users can connect to the database behind the website, and lately, due to increasing visitor numbers there are more connections, but also (which I only discovered recently) due to an increasing number of registered species and photographs some calculations (the ordering of the images) takes up more and more time, causing connections to be locked and blocking access for other visitors.

I have already prohibited access for Chinese bots, and I'm thinking of a complete rewrite of the way these long running calculations are done.

The result would be is that the site will be faster, and have less of these "max_user_connections" errors. To avoid the errors for now, I have disabled these long running calculations that determine which images (and in which order) should be shown in the lists. So until I rewrite this, some lists might remain empty and others will not be updated.

Thank you for your patience.

Kind regards,

Tim

Hallo Tim,

um eine Überlastung der Webseite zu vermeiden, rate ich allen Nutzern die Fotos nicht in voller Auflösung hoch zu laden.

Wir sollten die Fotos auf eine maximale Kantenlänge von zum Beispiel 1300 dpi begrenzen!

Das lässt sich mit jeder, auch Freeware-Software leicht mit wenigen Klicks machen.

viele Grüße Frank


Tim, at 2015-05-22 08:38:39, said:
Hello Frank,

the size of the images does not matter. The number of bytes transferred is not the problem. Big photos do not stress the system. It is the number of connections made to the database and that can only be influenced by me (by making code changes) or by having less visitors. Please continue to upload photos in the largest resolution you have. In another 5 years photos uploaded now of say 3 MB or less can be impractically small.

Kind regards,

Tim

Hello Baumsucher,

how did you mesure this tree? According to the list, the tree has been mesured at 1,30 m. As this is a double stemmed tree, which of the two stems did you mesure?

I have the idea that 2,78 m at 1,30 m is rather much for this tree.

Hallo Baumsucher,

bitte schau mal nach im Menü unter "Mehr" / "Baum-Umfang messen". Dort findest du die Regeln, wie wir hier messen. Diese sind nicht immer identisch mit den Messregeln der Forstwirtschaft. Als Beispiel findest du dort eine Skizze, die genau deinen Fall abbildet. Demnach nehmen wir als Stammumfang weder die Summe noch den Mittelwert beider Stämme, sondern den Umfang des größeren Stammes.

Auch wird bei Hanglage nicht vom höchsten Erdbodenkontakt aus gemessen, sondern vom Schnittpunkt der Stammachse mit der ursprünglichen Geländeoberfläche (vermuteter Keimpunkt/Pflanzpunkt).

Leider wird nicht überall nach diesen Regeln gemessen. Daher können die Werte aus verschiedenen Baumdatenbanken voneinander abweichen.

Karlheinz, at 2014-11-04 18:52:35, said:
Hi Leo, you could be right, the trunk with the many water veins looks like Ulmus laevis. But the leaves are different. I could compare directly with those of the 200 meters away Ulmus laevis '19794'. The leaves are thicker and solid, smoother the upper side, and the lower leaf surface shows the typical pattern of profiled Ulmus minor (it looks likehttp://www.baumkunde.de/Ulmus_minor/Blatt2/). But surely with the identification of the species I'm not. It would be good if you or someone else could check the tree on site!

please check out my additional photos of the leaves. I took a few home with me. The lower leaf surface shows a profiled or cracked pattern and I see silky hair tufts in the vein angles, focusing on the central vein. This is something I've only seen at Ulmus minor, is this also possible with Ulmus laevis?

your added leaf pictures show U. minor, but the leaves at your tree pictures are typical U. laevis.

I have added a photo showing an enlarged part of one of your tree pictures combined with a part of your collected-leaves pictures.

These cannot be from the same tree, because at the left side there are U. leaves trees and on the right side U. minor leaves.

U. laevis has much wider leaves with long curved teeth at the edges

U. minor has narrower leaves with short teeth

If this was a test, I hope I have passed, cheers, Leo

KoutaR, at 2014-11-07 11:17:27, said:
Most importantly, the leaves from fast growing sprouts or coppice shoots are unusable for identification - they readily result in missidentification. The best leaves are the subdistal ones (next below from the leaves at the shoot tip) from the short shoots (Kurztriebe) in the crown, including the lowest branches of the crown. Never leaves from the shoots at the tree base.

you are right Kouta, but even from leaves from the treebase or epicormic shoots, I will be able to distinguish U. laevis (which is my favorite tree) from other U. species.

Karlheinz, at 2014-11-10 15:55:44, said:
Leo,

einen Scherz habe ich mir nicht erlaubt und Verwechslungen oder falsche Zuordnung der Blatt-Fotos schließe ich aus. Auch ohne die Fotos erinnere ich mich daran, dass ich unter dem Baum neben den normalen Blättern zahlreiche dieser Feldulmen-ähnlichen Blätter gefunden habe. Sie hatten Nervengabelungen auch in der oberen Blatthälfte. Ich kannte dieses Unterscheidungsmerkmal und habe vor Ort sehr bewußt darauf geachtet.

Gestern war ich wieder in Gartrop, ich hatte aber leider keinen Zutritt zum Schlosspark. Über die Sprechanlage zur Hotelrezeption erhielt ich immer nur den Hinweis auf "Privatbesitz", zu weiteren Auskünften war man nicht bereit.

Ich kenne eine weitere Ulme, die als Flatterulme bekannt ist und wo ich zu Beginn der Laubfallzeit vor etwa einer Woche auch solche Feldulmen-ähnlichen Blätter fand: American elm (Ulmus americana) '19851' . Auch dort war ich gestern und habe Fotos gemacht. Die obere Kronenhälfte ist inzwischen völlig blattleer und unten rieselten die Blätter. Zu meinem Erstaunen konnte ich im dichten Laub unter dem Baum keine Blätter mit Nerven-Gabelungen in der oberen Blatthälfte mehr entdecken, nur noch normale Flatterulmenblätter.

Beide Bäume weisen ein übereinstimmendes Merkmal auf:

Durch baumpflegerische Eingriffe in der Vergangenheit wurde die Krone eingekürzt und an den Schnittstellen haben sich Büschel von Neuaustrieben entwickelt, welche nun die Kronenperipherie prägen.

Ich schliesse daraus:

Diese für Flatterulmen untypischen Blätter bilden sich an den Neuaustrieben oben in der Krone. Zu Beginn der Laubfallzeit sind das die ersten Blätter, die der Baum abwirft und die man dann unten auflesen kann. Später, wenn die große Masse der Blätter fällt, sieht man nur noch normal geformte Blätter.

Nach meiner Einschätzung ist das eine Flatterulme, ich habe das entsprechend geändert.

Was haltet ihr von dieser Theorie?

Grüße

Karlheinz

here is my English translation:

Leo,

a joke I'm not allowed and confusion or incorrect assignment of the leaf photos I exclude. Even without the photos I remember that I found under the tree in addition to normal leaves many of these field elm-like leaves. They had nerve forks in the upper half. I knew this distinctive feature and on site I have paid attention very consciously to it.

Yesterday I was back in Gartrop, but I had no access to the park. Over the intercom to the hotel reception I always received the reference to "private property", for other information they were not willing.

I know another elm, which is known as white elm and where I also found such field elm-like leaves at the beginning of leaf fall time, about a week ago: <American elm (Ulmus americana) '19851' . Even there I was yesterday and took pictures. The upper half of the crown is now completely empty from leaves and also below the leaves trickled strongly. To my amazement, in the dense foliage on the ground under the tree I could no longer find leaves with nerve forks in the upper half, only normal elm leaves.

Both trees have a matching feature:

By arboriculture interventions in the past, the crowns of both trees was shortened and the stumps have developed tufts of new sproutings, which now shape the crown periphery.

I conclude:

This for Ulmus laevis untypical leaves are formed at the sproutings in top of the shortened crown. At the beginning of leaf fall time these are the first leaves that the tree throws off and you can pick up from the ground. Later, when the large mass of leaves fall, you will find only normal shaped leaves.

In my estimation, this is a white elm, I have changed accordingly.

What do you think about this theory?

Recent photos of the flowers show: Ulmus laevis. I have learned from it: Also the leaves of European white elm can be very variable.

European white elm (Ulmus laevis) '19796'

Ich vermute jetzt, die Art dieser beiden Ulmen ist Ulmus americano

Now I assume, the species of these two elms is Ulmus americano

Beste,

Kan iemand mij helpen bij het determineren van een Acer opalus (Italiaanse esdoorn, '21002') in Waalre? Het blad komt hiermee volgens mij overeen, maar de stam is veel ruiger als wat ik heb kunnen vinden.

Kan iemand mij uitsluitsel geven of dit ook werkelijk een Italiaanse esdoorn is?

Mvg Hans Verbaandert

Hallo,

handelt es sich hier eventuell um Prunus sargentii?

Viele Grüße,

Hallo,

meines Erachtens eine Prunus serrulata 'Kanzan' (Japanische Nelkenkirsche). Dafür spricht schon der Habitus des Baumes.

El almendro malabar, almendro de los trópicos, almendrón o falso kamani (Terminalia catappa) es un árbol tropical de gran porte, dentro la familia de las combretáceas. El origen del árbol está en discusión, puede proceder de la India, o de la península Malaya, ó de Nueva Guinea.

Se desarrolla hasta una envergadura de 35 m, con una corona de ramas simétricas horizontales dirigidas hacia arriba. Cuando el árbol envejece, la corona de ramas se hace más aplanada, hasta formar una especie de jarrón.

Terminalia catappa se cultiva ampliamente en las regiones tropicales del planeta como un árbol ornamental, debido a la densa sombra que sus hojas proporcionan. El fruto es comestible, con un sabor ligeramente ácido.

La madera es roja, sólida y muy resistente al agua; se utiliza en la Polinesia para fabricar canoas.

este individuo que esta en la foto tiene aproximadamente 1 metro de fuste con 4 metros de altura de fuste limpio.

fue un error subir la foto ya que no era la especie indicada (no era ceibo, sino almendro) por eso la tuve que borrar mil didsculpas ya que no esta en la lista que mencionan de busqueda, gracias y saludos

Nur wegen der größeren Umfangmessung?

I have a hunch that these tall poplars will be one of the Black Italian hybrids (P. x canadensis). I should be able to identify the clone - particularly if you were able to photograph them over the next few months to show whether they carry male or female catkins and when/what colour the leaves flush. The shape of the tree can also be diagnostic.

Hi, thanks for this. Will try to get a photo of them soon, though it might be difficult as they are in a river valley.

Hello Owen, just to clarify these poplars are the Hybrid Black poplar, also would like to add that the height is estimated as the base of these two trees, which I think are the tallest, are within thick bamboo.

Hallo,

handelt es sich hier um 'Aspleniifolia' oder eher um 'Laciniata'?

Viele Grüße,

Rainer
