Taraxacum subintegrum
Overview
Taraxacum subintegrum, known as filtmaskros, is a specialized dandelion species distinguished by its deeply lobed leaves with distinctive filtering-like perforations and pale yellow flower heads that are notably smaller than common dandelions. This perennial herb plays a crucial role in its ecosystem by providing early-season nectar for specialized pollinators and serving as a host plant for several endemic invertebrate species.
Taraxacum subintegrum (filtmaskros) is critically endangered due to its extremely limited distribution in Scandinavia, where it faces habitat loss from agricultural intensification and urban development. The species is restricted to specific calcareous grassland habitats that are increasingly fragmented and degraded by human activities.
Habitat
Filtmaskros occurs exclusively in calcareous grasslands and limestone outcrops with thin, well-drained soils at elevations between 200-800 meters. The species requires specific microclimatic conditions found in semi-shaded areas near rock crevices where moisture accumulates but drainage remains excellent.
