Preslia is a peer-reviewed scientific journal publishing original research papers on plant systematics, morphology, phytogeography, ecology and vegetation science, with a geographical focus on central Europe. The journal was founded in 1914 and named in honour of brothers Jan Svatopluk Presl (1791–1849) and Karel Boivoj Presl (1794–1852), outstanding Bohemian botanists. It is published quarterly by the Czech Botanical Society.
