Uncinia is a genus of flowering plants in the family Cyperaceae, known as hook-sedges in Australia and as hook grasses or bastard grasses in New Zealand. The genus is characterised by the presence of a long hook formed by an extension of the rachilla, which is used to attach the fruit to passing animals (epizoochory), especially birds, and it is this feature which gives the genus its name, from the Latin uncinus, meaning a hook or barb.
