The 56th floristic summer school organized by the Czech Botanical Society was held in the surroundings
of the town of Jindřichův Hradec (southern part of the Czech Republic) in July 2017.
Studied biotopes included water bodies, wetlands, mires, different types of meadows, exposed fishpond bottoms, open sands, artificial spruce and pine forests, deciduous forests as well as ruderal sites. Floristic records were collected at 888 localities where 1017 taxa of vascular plants were found. In total, 14,536 floristic records were made.
Species are listed alphabetically, followed by numbers of respective localities. New sites were found for Carex otomana, Dryopteris cristata, Elatine orthosperma, Potamogeton alpinus and Spergularia marina. Many threatened taxa (e.g. Aphanes australis, Centunculus minimus, Dactylorhiza traunsteineri, Diphasiastrum tristachyum, D. ×zeilleri, Filago lutescens, Chenopodium vulvaria, Chimaphila umbellata, Littorella uniflora, Lycopodiella inundata, Pedicularis palustris, Pilularia globulifera, Melampyrum subalpinum, Sagina apetala subsp. apetala, Triglochin palustris and Vulpia bromoides) were confirmed at localities where they were known to grow.
