#269 They called me Populus tremula, also known as Populus sieboldii, Populus tremula var. sieboldii, Populus rotundifolia var. bonatii, and Populus bonatii. I pay homage to the male botanists Bonat (I couldn’t find his records), and Philipp Franz von Siebold, or Karl (Carl) Theodor Ernst von Siebold. They first catalogued me in 1753.
