Stringybark Eucalyptus | which is it?

Eric Frei · 13th February 2010, 06:16 PM

This one isn't that common around here but I do see it every now and then.

I am not sold on it being Eucalyptus carnea, Eucalyptus eugenioides, Eucalyptus psammitica or Eucalyptus acmenoides.... definately not Eucalyptus planchoniana.

bill24 · 13th February 2010, 08:49 PM

The bark isn't like any stringybark euc. that I know in Vic. Ekka.

Will check out few other things and let you know if I do any good.

Eric Frei · 13th February 2010, 09:01 PM

I might be going to the botanical gardens tomorrow, I think I know where one is there ... but lately a lot of bloody signs are missing, vandals have been pinching them.

Bernard Keays · 13th February 2010, 10:57 PM

Ekka,

I'm a bit stumped too. The bark doesn't seem typical of any stringybark's I know. It would be good to see some photo's of the upper canopy. Have you considered Eucalyptus seeana or bancroftii?

Done it · 13th February 2010, 11:05 PM

The only Stringy Bark I know doesn't look like that either. There's a pic here but I can't get it, Google Image Result for http://image05.webshots.com/5/7/95/88/67179588jnLjLb_fs.jpg

Contary to what I said in a previous post there are none around here now that I know of. Sometimes you'd find them growing with Iron Bark or Box, but not many.

Eric Frei · 14th February 2010, 02:15 PM

Well, after much searching I came up blank. Many of the older eucs in Mt Cootha gardens are not labelled, and I saw nothing really like this but the tree is rather juvenile.

So I think it's E carnea

I think that because those caps are still a little green and maybe by the time they drop off that rim might not be so pronounced and look like a carnea cap.

Can't place them Ekka, know the bark but its very typical of a few trees here in Vic, some redgums are close.

Doesn't seem the usual stringybark that I have cut thousands of posts from.

Would be nice to see upper branches, how high does the bark go, does it turn to bare/smooth white bark up higher?

Good ID question !

Eric Frei · 14th February 2010, 06:28 PM

It's persistent to the upper canopy but not to the branch tips. Same as E carnea.

This tree was in a group, hard to get a clear pic of it, but was maybe 0.25m DBH and 7m tall (juvenile)

bill24 · 14th February 2010, 08:51 PM

Found this pic. this seems to be a more typical stringybark that I see down this way (S/E Aus.).

APII database extract: photo_class = 'a' and photo_no = '18179'.

Just absolutely beautiful photos there Ekka, clear, descriptive. Just the type needed.

Another tricky one......*#!#*** eucs.

just thinking aloud here

one would assume that the valves when they open would become more exert. Somehow I have the feeling that they might become a lot more exert . Its just that tip that protrudes at the inside join of the valves The rim could become more rounded. Or they could stay the same. too hard a call.

The bark reminds me of E. apothalassica....?

is there an intermargin..?

I'm going to do a bit of research tommorrow, when I'm not tired, to see what I can come up with.

Regards Julie

Ekka,

after hours of trawling through books and the net, and I mean hours, I'm still not satisfied that the following, closest thing to it I could find, in attached doc is it, as it's out of range and you mention that you have seen others, but it's a possibility.

I keyed it using Flora of the Sydney Region by Beadle Evans and Carolin (Reed Publishers, Sydney) (revised 1972)

Perhaps Eucalyptus sphaerocarpa might be another option as well. It is described as having unusual bark compared to other Stringybarks. I could not find any photos of the caps to compare. I am not familiar with your Q.L.D Stringybarks and we do not have any thing like it here. I did notice yesterday that E. capittelata is decorticating at the moment in similar squarish strips, but it's definitely not that one.

Hope this might help, probably not.

regards Julie

Eric Frei · 19th February 2010, 06:56 AM

I'll have to go back there when it's sunny and get some more pictures and samples.

Bernard Keays · 19th February 2010, 09:34 AM

Julie,

I have had some discussions with another college. He thought that it might be hybrid… "possibly between E. bancroftii and E. resinifera. But if it’s a population of trees, then maybe it’s a new species, or an aberrant form of E. bancroftii". He was pretty certain that it wasn't Eucalyptus carnea.

jmcg.insight.gardens · 19th February 2010, 10:14 AM

Bernard

could be. It has the look of E.resinifera, hybrids are very common in Stringy barks.

Have found a key to Eucalyptus of the Greater Brisbane area

have to go meet some clients now

have a look later tonight.

Julie

Eric Frei · 19th February 2010, 08:05 PM

Does that mean I get to name the new one?

I wont name it anything stupid like the Poms did here.

....fancy having to say that to a customer when they expect you to instantly know the botanical name.

Hehehe, they would think you had been partaking of some rocket fuel before you'd come to work.......

Just think.... the Horticulturalists have to over there.

What would you name it Ekka?

Imagine................ Eucalyptus eric@treeworldii. ....................

Jeff Darby · 20th February 2010, 09:48 AM

lol..I like it..Eucalyptus treeworldii it has a ring to it...better put your hard hat on ekka...lol

Grower · 8th October 2011, 04:03 PM

Howdy, this is my first posting on here so if it works you should be able to see the pics. The question is, are these stringybarks? The odd thing is that the timber is red and not yellow as I was led to believe it was, we saw this when milling it ourselves yesterday. No idea as to how they got to be established where they stand or than to say an early settler must have sprinkled the seed about.

Eric Frei · 8th October 2011, 04:55 PM

Are the first two pics the same tree? Doesn't look so.

The second tree I reckon is likely a bloodwood.

The first is a bit of a mystery, really need those caps for eucs.
