Hi Brian - unlikely to be A. ukurunduense in Sichuan, that's from northeastern China: http://hua.huh.harvard.edu/china/mss/volume11/Aceraceae-AGH_coauthoring.htm
Let me see.Oh,none of you have got the right anwser. Please guess again.I will give you the right anwser,tomorrow. Here are sth about it.
1,It is not tall.About 2 meters high. 2,It grows on the high mountain(2000m~4000m),and it's very cold there (10 degree in July in daytime).

I have to say. It's very strange here.When I put out a post. It can't appear at once.And I can't put as many pics as I can. I can't understand some words,I don't know how to delete the pics I have put on the maple is Acer caesium. Do you know it?
It is because you have to confirm your email address. When you registered, you submitted an email address as yours. Three emails have now been sent to that email address with a link in them that you need to click on to confirm that the email address is yours. Once you have done so, then your messages will appear at once and you can put on many more pics.
Two more sets of photos on this site: http://www.botanicalgarden.ubc.ca/forums/showthread.php?t=9948 Acer caesium is said to have flowers in corymbs, unlike plant shown at top of this thread.
I'd wondered about this one when I was looking for ideas for my answer, but dropped it because the inflorescence is described as being a corymb, not an erect spike like this plant has
Maybe I have put on a wrong address. Because I haven't received any e-mails. It's **snip** Is it right.
I don't know much about maples. I think it is Acer caesium because the card reads it. It grows in a very famous mountain park in Sichuan. this kind of maple is ordinery there. and all of them has a card that says it is Acer caesium, I don't think such a famous park can make this mistake. Maybe a lot of corymbs form this kind of thing. Just like lavender.
Yes, that is the email address used. I've sent a fourth activation email. You can also send me an email directly to confirm: go to the contact info under my web page: http://www.botanicalgarden.ubc.ca/people/mosquin.php
Ron, you and Michael are real good with species forms and when you guys are on the same page people had better take notice. I went through the link Michael listed a couple of days ago and picked out a possible Maple and felt this one was not Acer caesium also when we were told what it was. Being familiar with a few areas of concern that others have had with some of the Chinese plants I would want to know how can the plant can be proven to be what even an expert said it was? Taxonomic keys are great but where was the evaluation done, with plants in the ground or plants brought into the lab or from analysis of various photos. Doesn't matter that much as I am not questioning the validity of the written material as I do not know enough about these plants to even begin there but I did question the flower spike and petiole color on the youngest growth for this one being Acer caesium. I looked at this one below a couple of days ago. Something to keep in mind is that in 1960 it was not so easy to bring plants into the US from China. In many cases these plants had to come from someone that originally got them from China, brought them into Japan and then we got our plants from people in Japan. Acer caesium ssp. Giraldii Wujiaofeng, yes even the most renown aboretums make mistakes with names. Sometimes it is too easy to take one person’s word for what a plant is rather than get a few other people’s opinions on what the plant should be named. Technical terms for taxonomic purposes really mean nothing out in the field if we cannot identify the plant upon sight without our books with us. The people that have to have their books with them to confirm what the plant is out in the open have already left themselves suspect in what they know about that plant is just my opinion as we either know the plant upon sight or we do not know it and if we admit we do not know it then we have use someone else’s interpretation or photo and hope that photograph is correct to help solve our mystery in what the plant may be. We always will run into trouble when names are placed on a tag or on a name plate when the person that named the plant for someone else was guessing and we see this happen a lot, even from the most knowledgeable of people. It used to drive some of us crazy trying to sort out what some people have done for names of these plants and the reasoning or lack thereof they used to come up with some of these names. The Maples of China opens up a whole new world for us to learn but some of these Maple were known in Japan from plant explorations into Korea and China. Even when China and Japan were at war with each other there were plants being shared amongst various people in both countries at great risk to them personally as you might imagine. Still, today much of what we know about the Maples of China comes from information that was written in the old and various Maples of the World books out of Japan. The more recent Maples of the World book by van Gelderen et all becomes of even more significance due to what those people had to sort out just to be able to compile much of anything about the Asian Maples as when we see even from the link Michael listed there is a lot of stuff that people had to deal with such as Acer caesium, Acer giraldii and Acer caesium ssp. Giraldii. I learned them being Acer caesium and Acer caesium var. giraldii as we felt they were both the same Maple but one was a variety of the other one. One of the Maples of the World books out of Japan listed Acer giraldii as being Acer caesium var. giraldii and with one of the Maples in the collection and the other one about a three hour drive away from us, we felt the Japanese botanists had these figured out right until we know differently and we left it at that.
