On the left is the foliage of a neighbouring common yew, showing the difference in foliage between that of the common yew and this tree.
Conifers, am 2015-01-20 17:56:37, hat gesagt:
Looks like just a long-leaved cultivar of Common Yew ;-)
wwhiteside97, am 2015-01-20 18:12:14, hat gesagt:
Thanks for this, didn't know there was a long leaved cultivar of the common Yew, bark is still different to other Yew trees though.
Martin Tijdgat, am 2015-01-20 18:14:27, hat gesagt:
WW and Conifers,

Longer leafs, more pointed leafs. I don't know the species, but is Taxus chinensis possible?

Greetings, Martin Tijdgat

foomanz, am 2015-01-20 21:11:18, hat gesagt:
If the fruit suggests a Podocarpaceae, then perhaps a Prumnopitys sp (sometimes called yew pines, along with Podocarpus macrophyllus). I'm not familiar with old world candidates.

Cheers,

Matt

Matt and Martin,

I will have a closer look at the tree tomorrow, it is very yew like in appearance but the leaves are nearly twice as long as the common yew and the bark is definitely softer than that of the common yew, you can peel tufts of it off.

Conifers, am 2015-01-20 23:59:13, hat gesagt:
I've seen one or more (un-named) Taxus baccata cultivar(s) with leaves this long. But the soft bark is odd; that doesn't fit any Taxus well. Cones ('berries') would help, if there are any, but January isn't a good time (and even in autumn, there's still a 50% chance it might be male!).

It isn't Prumnopitys andinus, and I doubt any other species in this genus either.

WiPe, am 2015-01-21 08:22:16, geändert am 2015-01-21 13:02:43, hat gesagt:
Prumnopitys and Cephalotaxus can be easily recognised when bending te leaves. When you bend them, and they break when bended completely, it will be most probably Prumnopitys or Cephalotaxus. If not, yu can exclude both genera.

Prumnopitys also has pale stomata where those of Taxus are green.

wwhiteside97, am 2015-01-21 12:22:43, hat gesagt:
Conifers, I will have a look for any signs of fruit or cones, but as you say it might be the wrong type of year for it.

WiPe, I will bend the leaves then to see and I'll have a look at the stomata, thanks for this.

wwhiteside97, am 2015-01-21 12:26:29, hat gesagt:
Conifers, the bark is softish and as I mentioned before you can also peel bits of it off in tufts, definitely not smooth or Flaky as common Yew is, especially for a tree this age.
Conifers, am 2015-01-21 17:45:13, hat gesagt:
Keep a look out for pollen cones too - they should be in bud or just starting to open at this time of year. Taxus scattered or in rows on the underside of the shoot, Cephalotaxus in dense rows on the underside of the shoot, Prumnopitys in stalked clusters.
WiPe, am 2015-01-21 18:57:54, hat gesagt:
I have added a foto of the stem of Prumnopitys andina. This stem is only 17 cm circumference, thus rather small.


In my opninion this tree is far to young to call it a monumental tree. i have just added fot your help on this one. I will not keep it on the side but for a few days.

I have also added an image of the backside of the needles. The needles are hardly bigger as those of Taxus baccata.


Conifers, am 2015-01-21 23:07:14, geändert am 2015-01-21 23:07:40, hat gesagt:
Prumnopitys andina again (at RBG Edinburgh), a male plant with pollen cone panicles developing bottom centre and right:

wwhiteside97, am 2015-01-22 15:30:58, hat gesagt:
Underside of P. Andina leaves look similar but the picture of the foliage from RBG Edinburgh shows no similarities, I will check the pollen cones this afternoon.
wwhiteside97, am 2015-01-22 18:15:13, hat gesagt:
Hello all, I've uploaded 2 images of what I found under the shoots on one of the branches.
Conifers, am 2015-01-23 00:28:54, hat gesagt:
Thanks! Those are dried-out / undeveloped Taxus seed 'cones'; so definitely a yew; most likely a cultivar of Taxus baccata, given the rarity of other yews in cultivation.
wwhiteside97, am 2015-01-23 01:05:29, hat gesagt:
Thanks! This would make sense as the tree is definitely very yew like in appearance and I actually thought it was a Yew until the other day when I decided to have a walk underneath it and found it to be slightly different.
Martin Tijdgat, am 2015-01-23 01:26:34, hat gesagt:
WW and Conifers,

So it is no longer an undetermined species, but "a" Taxus. Taxus baccata, Taxus x media, or another Taxus? Is there a picture of the whole tree?

WiPe, am 2015-01-23 13:56:50, hat gesagt:
Taxus celebica??? http://www.worldbotanical.com/taxus_celebica.htm

Or maybe another species from Taxus-sumatrana group???

http://www.worldbotanical.com/Key%20Taxus%20sumatrana%20grp.htm

Conifers, am 2015-01-23 18:28:19, hat gesagt:
Not Taxus sumatrana (syn. T. celebica); that has different, very distinctive foliage. I'd stick with a T. baccata cultivar.

As an aside, that www.worldbotanical.com website is highly unreliable, splits Taxus up into a multitude of "species" on the flimsiest of evidence; it is not accepted by any other taxonomists.

TheTreeRegisterOwenJohnson, am 2015-01-23 18:58:23, hat gesagt:
I can't add to this thread, other than to remark that Taxus cuspidata seems to be the only other Taxus that wants to reach tree-size in Britain/Ireland, and that the bark of the big old one at Borde Hill is a bit sponger and browner than common Yew, but the leaves are no bigger.
wwhiteside97, am 2015-01-24 15:58:16, hat gesagt:
Wouldn't be sure with the foliage of T. Cuspidata but the spongier bark sounds familiar. I wouldn't feel confident in distinguishing between the pair, are there any known cultivars of T. Baccata with spongier bark?

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.

Nice find! Well worth getting a six metre tape and measuring its girth accurately.


Need advice saving two sequoia
Für jedermann sichtbar · permalink · en
Brian, am 2014-12-16 03:35:28, hat gesagt:
I have two sequoia trees approximately 20m tall x 5m girth in scenic North Bend Washington, USA. One recently lost a limb, which unfortunately almost destroyed my neighbor's garage. My neighbor has engaged a lawyer to force me to cut these beautiful trees down. I would like to find an arborist expert on sequoia. I want to do all I can to save these trees from destruction. Is there an arborist in western Washington State that would be best for this assignment? Thanks

Brian.


RedRob, am 2014-12-17 16:22:08, hat gesagt:
Hello Brian, welcome. Not Washington state but not a million miles away and an arborist with a definite interest in redwoods to say the least is this guy:

http://www.mdvaden.com/

I would send Mario a message with your query and ask him his advice, if you send him detailed photos I imagine that he may be able to help even from a distance.


Brian, am 2014-12-17 16:52:15, hat gesagt:
RedRob, thank you for your help. I will follow your excellent advice.

RedRob, am 2014-12-17 16:57:00, hat gesagt:
You are very welcome Brian, hope that Mario can help save your trees. Perhaps you could register them on here to help with your cause against the lawyers?

The weather good in your area at the moment? I am in Yorkshire, England but have seen and have been following the coverage of the storm in California with the houses buried in mud from mudslides.


Brian, am 2014-12-18 03:07:06, hat gesagt:
RedRob, thanks again for the information. I was also able to find an arborist in a local town, Fall City, that may know about sequoia. It was a little to dreary to take premium pictures today. It should be nice tomorrow, before five days of forecasted rain.

I was not certain I should register my trees; they are not that big by sequoia standards. I have a Bigleaf maple (girth about 8 - 9 m) as well as cedars and firs that are larger. I'll take accurate measurements with the pictures tomorrow.

The weather here is very nice. We are not getting pounded by the storms that are rolling through California.


Conifers, am 2014-12-19 14:20:33, hat gesagt:
Just seen the photo - nice tree! It's a Coast Redwood Sequoia sempervirens, not a Giant Sequoia Sequoiadendron giganteum (so of even more value, as less commonly planted).

Brian, am 2014-12-19 17:12:41, hat gesagt:
Thanks for the feedback. Very much appreciated.


Quercus Hispanica and Q x Hispanica Lucombeana
Für jedermann sichtbar · permalink · en
wwhiteside97, am 2014-12-18 16:42:57, hat gesagt:
Could someone tell me, is it Q x Hispanica that keeps it's leaves all year? And 'Lucombeana' that loses most but not all of its leaves? I recently uploaded a 5.18m oak which I think is Q x Hispanica as it still had all its leaves(this was in mid November). Would I be correct in saying this?

Conifers, am 2014-12-18 17:42:32, hat gesagt:
Quercus × hispanica is the name which covers all hybrids between Turkey Oak and Cork Oak; so it is very variable, and of course includes 'Lucombeana' as a sub-set.

TheTreeRegisterOwenJohnson, am 2014-12-18 17:52:54, hat gesagt:
The commonest clones of Q. x hispanica in Britain and Ireland are 'William Lucombe', which should have about 80% of its leaves left in December and 20% by March, and an unnamed corky-barked clone grafted at the base on Turkey Oak, which is almost completely evergreen. Rarer clones include 'Fulhamensis' which loses most of its leaves after Christmas and a few unnamed deciduous clones. 'William Lucombe' is the only clone that regularly reaches 5m girth with a good single bole.

wwhiteside97, am 2014-12-18 18:18:57, hat gesagt:
Thanks, this makes things clearer, I shall upload an image of the tree as it is at the minute. The trunk was hidden away for many years by Rhodo Ponticum until these were cleared about 5 years ago and until this time you couldn't see the size of the trunk.

wwhiteside97, am 2014-12-18 19:26:03, hat gesagt:
Just as a matter of interest, what size of leaf has 'William Lucombe'? There are 2 other Lucombe oaks in the forest with quite a big leaf but the leaves on this tree are smaller than these ones.

TheTreeRegisterOwenJohnson, am 2014-12-18 21:15:45, hat gesagt:
'William Lucombe's' leaves are Turkey-Oak sized but more regularly lobed. The most vigorous examples might have slightly bigger leaves - it's probably the biggest-leaved clone (or group of clones perhaps by now) of Q. x hispanica. Q. castaneifolia is always a possibility for a look-alike with significantly longer leaves: this is deciduous but can hold only its dead leaves through winter.

Conifers, am 2014-12-18 21:35:37, hat gesagt:
Even Quercus cerris is only just starting to shed leaves in the last few days around here

wwhiteside97, am 2014-12-18 22:23:07, hat gesagt:
Probably is one of the larger leaved clones then, I will upload a photo of the leaves of this particular tree and of the other Lucombe oak which I have added to this site.

Thanks.


wwhiteside97, am 2014-12-19 13:59:00, hat gesagt:
I have uploaded pictures of the two trees, both are not the same examples but are the same species of tree. The 5.18 tree is exactly the same species as the one I have uploaded with nearly all of its leaves still on. The other Lucombe Oak? I have uploaded has nearly all of its leaves gone, I have also uploaded images of the leaves of both trees.


Turkije = Azië of Europa of allebei?

Wim Brinkerink, am 2014-12-12 22:40:00, hat gesagt:
Hi Tim,

Ik heb net een tripje naar Turkije gemaakt. Wel wat aardige bomen gezien. Ik ga ze plaatsen. Een kernvraag is echter of op onze database Turkije alleen Europa is (bestaand0 of ook via Azië benaderd/bereikt kan worden. Ik heb de neiging om nu mijn bomen onder Turkije, Europa te uploaden. Dat is wellicht niet correct, omdat Antalya en Cappadocië tot het werelddeel Azië behoren.


Martin Tijdgat, am 2014-12-12 23:31:46, hat gesagt:
Wim,

Wees hier helder en transparant. De Bosporus en Zee van Marmora vormen de grens tussen Europa en Azie. Bomen ten westen van deze wateren horen in Europa te worden geregistreerd. De overige bomen horen in Azie thuis.

Groet, Martin


Wim Brinkerink, am 2014-12-13 00:09:51, hat gesagt:
Hi Martin,

Staatkundig klopt dat. Turkije is voor een klein deel Europa en een groot deel Azië. In onze database is Turkije echter geheel onder Europa geclassificeerd. Dus alle provincies staan onder Europa. Ik kan (geloof ik) geen bomen onder Turkije Azië invoeren tenzij ik me vergis. Tim moet daar maar uitsluitsel over geven. In essentie vind ik echter wel dat het grootste deel van Turkije staatkundig onder Azië valt.

Cultureel denk ik daar genuanceerder over sinds mijn laatste bezoek,

Maar dat doet er niet echt toe. We hebben hier toch een staatkundige classificatie?

Groet Wim.


Conifers, am 2014-12-13 14:50:18, hat gesagt:
Russia is of course also in both continents, which could be significant if we get many trees there.

For completeness, Kazakhstan also has (a small) part in Europe, part (most) in Asia. Mostly treeless steppe, but there could be some large Populus or Salix on the banks of the Ural River (the boundary between Europe and Asia there).


Wim Brinkerink, am 2014-12-13 19:14:01, hat gesagt:
Hi Conifers,

I agree that more diffuse situations exist. Concerning Turky, the only European part of Turky is the west of Istanbul. The overwhelming rest of the country is Asian Let's say about 99%. In this database I haven't any problems if Tim decides that Turky belongs Europe. Politically I have problems with that idea, but we are not in politics here.

RedRob, am 2014-12-11 18:16:34, geändert am 2014-12-11 18:21:27, hat gesagt:
Could I ask a question, the small blue Douglas Fir here, is this going to be just a normal Douglas Fir or could it be the variant 'Glauca'? I noticed it in particular when I measured these trees a couple of years ago now but didn't really think anything about it and wasn't aware that there was a 'Glauca' type then. The reason that I ask is that I have noticed another very bluey tree in another photograph in a group of trees which the laser measured at 48 metres in Aug 2012. I have uploaded a photograph of it (bottom photo) it is directly in the centre of the photo and clothed with foliage right down it's trunk.

Conifers, am 2014-12-12 01:25:45, hat gesagt:
Unlikely, but not impossible. You'd need to get a close-up of the foliage and (preferably) a cone.


Scottish storm

Conifers, am 2014-12-10 23:55:36, hat gesagt:
With wind speeds of up to 230 km/h (144 mph) reported — admittedly on treeless St Kilda — there's going to be a lot of trees down.

Any news on losses yet?


RedRob, am 2014-12-11 18:24:49, hat gesagt:
Hello Conifers, incredible winds, 81 mph here at High Bradfield near Sheffield yesterday, 61 mph at Emley Moor which I suspected as the TV is being affected at the moment.

There is a gardening programme on BBC2 in the mornings called 'Great Gardens from above' with Christine something in a balloon. I couldn't catch it but this morning she was in Northumberland, I wondered if she could have been at Cragside? Did you see it Con? I would love to see the trees at Cragside from above, would be spectacular.



Monkey puzzle in Gosford Forest Park
Für jedermann sichtbar · permalink · en
wwhiteside97, am 2014-12-08 22:48:22, hat gesagt:
Can anyone tell me why Monkey Puzzles die? in the last 10 years there have been 5 that have died in Gosford, including the county champion girth tree. One month they are growing fine then the next they show signs of dying.

Conifers, am 2014-12-09 01:28:27, hat gesagt:
Likely root disease (Phytophthora or similar) after wet years.

In the wild they grow on very free-draining volcanic ash; Britain's boulder-cay soils are not good for their long-term growth.


wwhiteside97, am 2014-12-09 19:04:39, hat gesagt:
Thanks, that would make sense as the ground these 5 trees were growing on was generally quite wet.
