Abstract
Pimpinella pygmaea A. Sajan, Navya & Sujana (Apiaceae) is described as a new species from Karimpuzha Wildlife Sanctuary, Kerala, India. It shares morphological similarities with P. candolleana, P. leschenaultii and P. tomentosa, but can be distinguished from them by several morphological features, including plant height, leaf size and shape, number and size of rays, number of flowers, and surface of the schizocarp. A detailed description, including habitat, phenology, photographs and scanning electron micrographs of the schizocarp, is provided.
