Description | Lappula semicincta (Boraginaceae), a critically threatened species of the Czech flora, has been reported to occur in the Czech Republic in just a small area in south-western Moravia. The last record dates from 1980. During a field survey and a search in four regional herbaria, we recorded two extant populations of the species and found specimens from another three sites where the species had been collected in the past. All the sites are located in south-western Moravia between the Oslava River valley south-west of Brno city in the north and the Dyje River valley near the border with Austria in the south. The species inhabits warm and dry non-forest habitats in or near deep river valleys with base-rich skeletal soils. Semi-natural dry grasslands often prevail at these sites; however, L. semicincta usually occurs in disturbed places, often influenced by past or recent human activities. |
