New taxa described in Grisebach’s “Spicilegium Florae Rumelicae et Bithynicae” (1843-46)

An account is given of August Grisebach’s journey through northwestern Asia Minor (“Bithynia”) and the interior of the Balkan Peninsula (“Rumelia”) in 1839. Extensive collections were made in what is now north-west Turkey, northern Greece, the Republic of Makedonija, Kosovo and northern Albania. More than 300 new taxa were described in the Spicilegium, based primarily on Grisebach's own collections, but also on material gathered by others (Frivaldszky, Friedrichsthal, Pestalozza and others). These taxa are typified as far as possible, and notes on taxonomy, nomenclature and distribution are provided in most cases.
