Validation of Carex×marshallii ( = C. lepidocarpa×C. saxatilis, Cyperaceae)

Abstract

Abstract The hybrid between Carex lepidocarpa Tausch and C. saxatilis L. is well known as C.×marshalli A. Benn. This name is not supported by either a description or a type specimen and is therefore a nomen nudum. This hybrid is here named C.×marshalii A. Benn. ex Blackst. & Col. Sm., hybr. nov. A specimen from Bennett’s herbarium collected by E.S. Marshall has been designated here as the holotype and a full description of the hybrid is given.
