Dosad su u Glasniku Hrvatskog botaničkog društva objavljena tri priloga koja popis flore Hrvatske i bazu podataka Flora Croatica (http://hirc.botanic.hr/fcd) dopunjuju s novoopisanim i novootkrivenim biljnim svojtama te se provode nomenklaturne preinake već postojećih svojti. Kako bi se taj niz i dalje nastavio, ovaj prilog je četvrti u nizu te je u bazu podataka Flora Croatica dodano sedam novih biljnih svojti (Glaux maritima L., Cystopteris dickieana R. Sim, Teucrium x rohlenae K. Malý, Helianthemum jonium Lacaita & Grosser ex Bég., Ornithogalum sibthorpii Greuter, Carex phyllostachys C. A. Mey. i Amaranthus tuberculatus (Moq.) J.D. Sauer) koje se po prvi puta bilježe za Hrvatsku. Till now in the Journal of the Croatian Botanical Society three contributions were published that serve as an update of the Flora Croatica Database (http://hirc.botanic.hr/fcd) with new entries of a newly described plant taxa and new discovered taxa in the flora, as well as nomenclatural changes were applied on already existing plant taxa. In order to continue this series, this contribution is the fourth in a series and seven new plant taxa (Glaux maritima L., Cystopteris dickieana R. Sim, Teucrium x rohlenae K. Malý, Helianthemum jonium Lacaita & Grosser ex Bég., Ornithogalum sibthorpii Greuter, Carex phyllostachys C. A. Mey. i Amaranthus tuberculatus (Moq.) J.D. Sauer) have been added to the Flora Croatica Database, which are being recorded for the first time in Croatia.
