Description

Carex pulicaris is a small sedge, with stiff stems Template:Convert tall.<ref name="Jermy">Template:Cite book</ref> The leaves are Template:Convert long and less than Template:Convert wide.<ref name="Jermy"/> The inflorescence comprises a single spike, with 3–10 female flowers towards the base, and male flowers towards the tip.<ref name="Jermy"/><ref name="Skye">Template:Cite web</ref> 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.<ref name="Jermy"/> Before the utricles have become deflexed, C. pulicaris closely resembles C. rupestris, with which it often grows.<ref name="Jermy"/> It may also be confused with C. pauciflora, which usually bears only 2–3 fruit per stem.<ref name="Skye"/>
