Several trees on our street. Gray bark, compaund leaves with 9 leaflets, second year I am looking for any flowers or fruits, but don't see them Can it be hickory or walnut?
Is the leaf arrangement opposite as it appears? If so it can't be either since they're alternately arranged along the branch. Fraxinus excelsior?
I wonder if it is another Fraxinus sp? See 2nd pic, leaflets on left show very clearly. Leaflets on Common ash.... Fraxinus excelsior are stalkless. Veins also differ from pics posted here by Nadia. In UK they flower and produce masses of seeds from a young age. Blinking pest of a tree. http://luirig.altervista.org/cpm/albums/bot-units08/fraxinus-excelsior5115.jpg Could it be Fraxinus pennsylvanica? Veins seem to fit. Or Fraxinus americana which has longer stalks? http://www.southeasternflora.com/viewfull.asp?picid=2837 http://www.uwgb.edu/biodiversity/herbarium/trees/fraame01.htm
You are right, leaves are opposite.I don't think it could be too fancy tree, because they are city trees, so bought from local nursery, just I don't have a house or any land, not familiar with any nurseries and don't go there.
Fraxinus excelsior? I check description. The leaves are often among the last to open in spring, and the first to fall in autumn if an early frost strikes; they have no marked autumn colour, often falling dull green. True The flowers open before the leaves, the female flowers being somewhat longer than the male flowers; they are dark purple, and without petals, and are wind-pollinated. Both male and female flowers can occur on the same tree, but it is more common to find all male and all female trees; a tree that is all male one year can produce female flowers the next, and similarly a female tree can become male. The fruit is a samara 2.5-4.5 cm long and 5–8 mm broad, often hanging in bunches through the winter; they are often called 'ash keys' As I said, I've never seen flowers or fruits. I look at these trees every day, I know Fraxinus flowers, I just couldn't miss them, fruits and flowers both.
Actually, I don't know what to say!I didn't think about these trees as ashes! I checked all links and wikipedia and probably, this tree is an ash. I just didn't expect that decision. Backside of the leaves is not whitish, I have pictures of underneath, they are green.Number of leaflets are at least 9. I would take pictures of leaf scar. But I am not so particular, it is enough to know that kind of Fraxinus, I read that it is common to plant in the city. Thank you!
The characteristics of the winter buds should be illustrative. Meanwhile, they might have the same kind of tree, with a label, in a local collection such as at Van Dusen.
I think Nadia has examined every tree at VanDusen, and at UBCBG too. Well, it's possible she missed something.
Sometimes it helps to have a lead on which genus you need to be studying. Does Van Dusen have an "area" containing Fraxinus trees or are they dotted all over? Most Botanical gardens can produce an alphabetical list of trees with map and ref number of where to find named trees.
If everybody agrees at Fraxinus, I am satisfied without specific ssp., would wait for fruits and flowers in coming years.
This is not true. If I look at every tree, what most people do in the garden, it doesn't mean I remember and can recognize even 1/3 of them. Most of the time I can see ashes but I never even thought about these ones on my street as ashes. Maybe they are too young, look very pretty,leaves are too big, no flowers, no fruits and so on...
I can't believe. I took a leaf and measured, it is 51cm long, leaflet 17 cm long, 6cm broad This is from wikipedia http://en.wikipedia.org/wiki/Fraxinus_excelsior The leaves are 20–35 cm long, pinnate compound, with 7-13 leaflets, the leaflets 3–12 cm long and 0.8–3 cm broad
What a shame your tape measure is covering some of the clues... ie where the leaflets are attached to the stalk. Which was the reason I said it could not be Fraxinus excelsior!
Wikipedia's Fraxinus americana (White Ash) article says the "lower sides of the leaves of White Ash are lighter in color than their upper sides, and the outer surface of the twigs of White Ash may be flaky or peeling". And the petiolules (leaflet stalks) should be downy. How do these characteristics fit, Nadia? Silver surfer, I see what you mean about the shorter petiolules on the Green Ash. The leaflet 2nd from the bottom at the right would indicate that it's not that.
It is the same leaf, it didn't dry, looks very fresh. I think, underside looks whitish, it didn't when I took pictures outside...
