Miterwort grows from a rhizomatous root system with fibrous roots. Leaves are coarsely toothed with 3-5 shallow lobes.<ref name="flora">Template:EFloras</ref> Most leaves are basal, and there is one opposite pair of stemless leaves on each flower stalk.

Tiny flowers with finely divided, lacy white petals are produced in mid-spring in racemes on stems growing from Template:Convert tall.

The seeds are tiny, Template:Cvt,<ref name="flora" /> produced in small green cups, formed from the sepals of the flower, and when ripe are shiny and black.<ref name="minnesota">Template:Minnesota Wildflowers</ref> They are spread when raindrops hit the cups and splash the seeds out.<ref name="illinois" />
