Plants in the genus can either be Annual plant, annuals or perennials. Perennial plants in ''Microseris'' usually have a taproot or a caudex with the exception of ''Microseris borealis'', which is rhizome, rhizomatous.

Plants of the World Online (POWO) Synonym (taxonomy), synonymizes genus ''Nothocalais'' into ''Microseris''. While the USDA Natural Resources Conservation Service PLANTS database (PLANTS), World Flora Online (WFO), the Global Compositae Database (GCD), and Flora of North America (FNA) continue to list ''Nothocalais'' as a separate genus as of 2023. The only species classified by WFO in ''Nothocalais'' is ''Microseris nigrescens'' as ''Nothocalais nigrescens'', which is also the classification in PLANTS and FNA. The other species classified by PLANTS and FNA as ''Nothocalais'' are ''Microseris alpestris'' (''Nothocalais alpestris, N. alpestris''), ''Microseris cuspidata'' (''Nothocalais cuspidata, N. cuspidata''), and ''Microseris troximoides'' (''Nothocalais troximoides, N. troximoides'').
