''Carex pulicaris'', the flea sedge, is a species of sedge in the genus ''Carex'' native to Europe. ==Description== ''Carex pulicaris'' is a small sedge, with stiff stems tall. The leaves are long and less than wide.〔 The inflorescence comprises a single spike, with 3–10 female flowers towards the base, and male flowers towards the tip.〔 As the utricles mature, they bend away from the spike axis and become sensitive to touch; the way the seeds appear to jump from the stem gives rise to the plant's vernacular name.〔 Before the utricles have become deflexed, ''C. pulicaris'' closely resembles ''C. rupestris'', with which it often grows.〔 It may also be confused with ''C. pauciflora'', which usually bears only 2–3 fruit per stem.〔
