Will, I took the A. saccharum
height from here:http://www.nativetreesociety.org/bigtre ... e_list.htm
Indeed, it seems to be a Kalanu Prong tree. What is the actual height record for A. saccharum
? 144.2 ft?Carya
and many others grew in Europe before the Ice Ages but many geographical structures in Europe (the Baltic Sea, the Pyrenees, the Alps, the Carpathians, the Mediterranean Sea) are west-east oriented - bad thing for species migrations in front of the flucuating glaciers.
Comparing subgenera instead of genera is a good idea but I think it should then be done for all the genera - otherwise we are biased towards the charismatic genera. Unfortunately, we have no reliable measurements for the European soft pines. Pinus sibirica
in southern Russia may reach about the same height as P. sylvestris
and P. nigra
. There are no red oaks in Europe.
Matt, I have got the Cornus florida
height from a message on the BBS or from an e-mail. I cannot find the source for now. Nice if somebody confirms the height.
