Florian Porcius (August 28 [O.S. August 16] 1816–May 30 [O.S. May 17] 1906) was an Austro-Hungarian ethnic Romanian botanist and administrator. Born in Rodna, a village in Transylvania's Bistrița-Năsăud County, he came from a poor peasant family, and his parents were Precup Șteopan and his wife Ioana. He was raised by his grandfather, the priest Gherasim Porcu (Latinized as Porcius), whose name he took by adoption. In 1824, he entered the primary school in Rodna, for miners' sons, where he began to pick up the German and Hungarian languages. From 1827 to 1831, he attended the German-language military normal school in Năsăud, followed by the high schools in Blaj and Cluj from 1833 to 1836.
