Anyway looking for synonyms for Betula tianschanica and came across this
_really_ useful site: http://www.theplantlist.org There is a simple
search which either gives you the accepted name and its synonyms or tells
you which accepted name your entry is a synonym for. This later is
especially useful when trying to navigate in the land of the obscure...

You have to treat it with a touch of caution. It's the best single
source online, but it's not accurate for all groups of plants.
