Chouardia lakusicii (Šilić) Speta, a very rare species in the Croatian flora, was discovered during a study of the karstic flora on the Torac and Ivanova lazina mountains above the villages of Majkovi and Mravinjac, northeast of the village of Slano (Southern Dalmatia, Croatia). Previously, this species in Croatia had been only described in one locality, north of Mt. Biokovo (the Zabiokovlje area). The present specimens were recorded at elevations of 720 – 780 m, within open rocky limestone and in the crevices in limestone blocks. The populations showed good viability. According to the International Union for Conservation of Nature methods for threat assessment, we propose that Ch. lakusicii should be included in the category of vulnerable taxa (VU; criteria A3C, B2A, b (ii, v)) and included in the national red list.Chouardia lakusicii (Šilić) Speta je vrlo rijetka vrsta Hrvatske flore. Do sada je ta vrsta u Hrvatskoj zabilježena na jednom lokalitetu, i to sjeveroistočno od planine Biokovo (Zabiokovsko područje). Nedavno smo je otkrili na brdima Torac i Ivanova lazina iznad selâ Majkovi i Mravinjac, sjeveroistočno od naselja Slano (južna Dalmacija, Dubrovačko primorje) na nadmorskoj visini od 720 do 780 m. Raste na otvorenim stjenovitim vapnencima i u pukotinama vapnenačkih kamenitih blokova. Populacija je dobro održiva. Temeljem metoda procjene ugroženosti Međunarodne Unije za očuvanje prirode, predlažemo uvrštavanje Ch. lakusicii u nacionalni crveni popis ugroženih vrsta u kategoriji osjetljive svojte (VU; kriterij A3C, B2A, b (ii, v))
