Hi Alex, According to 'Maples of the World', described in 1922 by Pax & Hoffmann. It is said to be much like A. campbellii. It is kept apart from that species for lack of sufficient information although it eventually might be synonymous. Gomero
The Flora of China draft text treats it (and Acer campbellii) as a synonym of Acer oliverianum subsp. oliverianum Pax.
ciao Gomero Maples of the World is for me the best complete book for maples but is printed in 1994 and how Dirk van Gelderen write is "eventually" and this cultivar not avaible in the trade, in this moment is avaible!!! Con amicizia alex
Online Flora of China had Betula albosinensis listed as a synonym of B. utilis, without discussion awhile back so I wonder if all determinations presented there are valid and accepted.
Here are a couple of pics of my A. schneiderianum, 6 June 2015, planted April 2009. It was very difficult to acclimatize here and suffered from major pseudomonas wounds on the trunk; I really thought it would die. However it does seem to be settled in now and the wounds have healed. Although I don't have a picture the bark is very attractive and has a blueish striation. Samaras are bright red and often fertile, though no doubt hybrid more often than not. As for the taxonomic status, theplantlist.org lists A. schneiderianum as the confirmed name. Flora of China seems to have subsumed schneiderianum as oliverianum ssp oliverianum (per Michael's comment) but this doesn't seem accepted elsewhere. For me it is different from the individuals of oliverianum I am observing on the face of it,for example the leaves have a much more leathery texture. -E
mine is dead 3 years ago after two weeks with temperature under zero,is very difficult grown in my usda zone :( but i'm happy for your emery :) if born some flowers and after seeds send me !
I'll definitely send you some seed next time it sets, Alex. Though as I said it is unlikely to be true to the parent.
