}}Carex sect. Spirostachyae is a section of the genus Carex, containing 38 species of sedge. Species in Carex sect. Spirostachyae share a suite of features, including the short internodes of the primary rhizomes, the presence of an antiligule, the leaf-like, sheathing bract at the base of the inflorescence, the presence of three stigmas in female flowers, and the shape of the seeds.[1]

The section is composed of two subsections, with differing edaphic preferences; subsection Elatae comprises species that lives on acidic soils, while those in subsection Spirostachyae live on basic or ultramafic soils.[1] The two sections also differ morphologically, with species in subsection Elatae having wider leaves, thicker stems and larger spikes, the lowest of which may hang downwards.[1]

The centre of diversity of the group is in Europe and adjacent parts of Africa and Asia; a few species occur in Australia, Africa, South America and on oceanic islands.[1] The three species present in North America are introductions.[2]
