In order to build up data infrastructure on the horology of Croatian vascular flora, the present data on the distribution of taxa from the class Sphenopsida were collected from literature and herbarium sources. For 9 taxa of Croatian flora, 705 localities were found, 176 of the localities of herbarium specimens and 399 localities cited in literature being geocoded. The distribution was represented with a list of localities and maps by using a Central European grid for floristic mapping (MTB). The amount of data for single areas showed that the mountain macro-region, the Pokuplje meso-region, the Zagorje meso-region and the western part of the Gornja Posavina meso-region were better investigated.U svrhu gradnje podatkovne infrastrukture o horologiji vaskularne flore Hrvatske sabrani su postojeći dokumentirani podaci o rasprostranjenosti svojti razreda Sphenopsida iz literaturnih i herbarskih izvora. Za devet svojti flore hrvatske nađeno je ukupno 705 nalazišta, a geokodirano je 176 lokaliteta sabiranja herbarskih primjeraka i 399 lokaliteta navedenih u literaturi. Rasprostranjenost je prikazana popisom nalazišta i kartama, uz upotrebu srednjeeuropske mreže za kartiranje flore (MTB). Količina podataka za pojedino područje ukazuje na veću istraženost planinske makroregije, te pokupske, zagorske i zapadnih djelova gornjoposavske mezoregije
