Acer heldreichii Boiss.
Acer heldreichii is a medium-sized tree, probably endemic to mountains of the C & S Balkan Peninsula southwards to N Peloponnisos. It grows at rather high altitude and is never abundant. The specific epithet commemorates Theodor von Heldreich (1822–1902), a German botanist who spent most of his life in Greece and was a leading explorer of the Greek flora over a period of almost 60 years.AA.
