Tree identification please
I'e got this delicate little tree in the garden. At 25 years approx
it has stretched up to about 6m tall, and is about 150mm diameter at the bole. It has tri-lobed divided leaves with pointed tips, and a smooth, non-waxy surface. The best chance of identifying it is when if flowers, as long, fine, catkins. I'e taken pictures. http://www.brunnian.f2s.com/pictures/catkin1.jpg (72Kb) http://www.brunnian.f2s.com/pictures/catkin1.png (1.4Mb) http://www.brunnian.f2s.com/pictures/catkin2.png (2.8Mb) Given that I have never seen any fruits, I think it is male! Any ideas what it might be? Anyone? |

Thanks, and a fair fit on the leaves - mine is not hairy, however. nor is the flowering anything like. It's puzzled me this one for years. |

Thanks, and a fair fit on the leaves - mine is not hairy, however. nor is the flowering anything like. It's puzzled me this one for years. Could you try a closeup of the flowers? (Cut off an inflorescence and photograph against a sheet of paper?) There's not many ternate-leaved trees commonly planted in Britain, and none of the ones in Mitchell looked a better match foliage-wise that laburnum. (Except as far as I could tell, your tree as opposite-leaved foliage, and laburnum is alternate-leaved.) There's a number of ternate-leaved maples. (The 'catkins' look as if they could be composed of immature maple fruits.) I don't think it's the paper-bark maple, Acer griseum, as that has distinctive bark, and distinct side-lobes to the basal leaflets. The rough-barked maple, Acer triflorum, also has peeling bark and side-lobes to the basal leaflets. The other two ternate-leaved maples in Mitchell are the Nikko maple, Acer nikoense, and the vine-leaved maple, Acer cissifolium. (Also, all these flower in May, so we wouldn't be expecting to see immature fruits at this time.) The population of Acer campestre on the ridge between Portishead and Clevedon is also ternate-leaved, but it's clearly not this, as Acer campestre bears its flowers erect. Other trees with ternate leaves are some hickories (Carya) and common walnut (Juglans regia) - there are alternate-leaved, and not (at least usually) consistently ternate. BTW, it's possible to perform a considerable lossy compression of your images with limited loss of quality. -- Stewart Robert Hinsley |

I'd like to see a good close up of individual flower. Rod Weed my email address to reply http://website.lineone.net/~rodcraddock/index.html |

The message
from "Robert E A Harvey" contains these words: Check out Voss's Laburnum. Thanks, and a fair fit on the leaves - mine is not hairy, however. nor is the flowering anything like. It's puzzled me this one for years. I looked at the first pic, but the other two were far too big and would have taken too long to download over a dial-up connection. A jpg of the whole tree and another of the bark might be a help. -- Rusty Open the creaking gate to make a horrid.squeak, then lower the foobar. http://www.users.zetnet.co.uk/hi-fi/ |

I emailed a pic to David Poole and got this reply: "It is an Acer and it is almost certainly the highly variable Acer negundo - and the images seem to portray mainly male inflorescences they are very typical of the species. I've attached a pic of this Acer at a slightly earlier stage and it is virtually identical. This Acer can carry numerous leaf types on the same tree or just a single leaf type. Geographical variations may exhibit pinnate, ternate or even simple leaves and leaf margins can be serrated, indented or not." For those who joined the group recent, David was - and I hope he will be again when less busy - an immensely knowledgeable member of urg.

That's very interesting indeed. I've followed up all the other suggestions very carefully, and they all appear to be blind alleys. This one seems about spot-on, except two other references descibe the male floiwers as corymbs; which I associate with an upright habit and all the florets forming a plane. These are variable length and dangling. However these photos from authorative sources seem to have clinched it: Male: http://www.funet.fi/pub/sci/bio/life...negundo-1m.jpg female: http://www.funet.fi/pub/sci/bio/life...negundo-2f.jpg The parent web site also gives an English common name: Ash-leaved Maple, which is nice I also found, following your clues, Acer Negundo Californium http://elib.cs.berkeley.edu/cgi/img_....+californicum where the florescences are much more exuberant then my little delicate thing - though the picture of the main tree shows the same sparse leaf cover even when fully developed. So, a male Acer Negundo (Box Elder, Ash-Leaved Maple) will do for me. Now, the next interesting bit. How did it get here? The examples above suggest a north american range, on the atlantic seaboard, although two of the photos are from Finland. Is mine a weed, or did a previous owner purchase it - and if the latter, was it once sold commonly in garden centres? It's perfect where it is, slow growing and small, and I like it a lot. For those who joined the group recent, David was - and I hope he will be again when less busy - an immensely knowledgeable member of urg. I've never known him wrongly identify anything. My thanks to both of you. |
