The RHS Index lists Zelkova schneideriana, (sic)

Thanks for the tip. There is abundant information on the Web both under the
correct name of Z. schneideriana and the corrupted "Schneidria."
Z. schneideriana is a valid species. It is listed as coming from Hunan and
Yunnan provinces. It was discovered in Hunan in 1918 and pulished by Heinrich
Handel-Mazetti in 1929. Common names are Schneider zelkova and Chinese zelkova.
Leaves turn golden yellow in the fall. It is hardy in the ground to about -3 F
(-10 C). According to one reference, as a bonsai it is considered
warm-temperate to subtropical. If it is grown as a subtropical it is evergreen.
If it is grown colder, it is deciduous. The pictures look more like Chinese elm
than Zelkova serrata, but that may be because of the way the Chinese prepare it
for export.
