    Abstract

    Fimbristylis prasadii, a new species of Cyperaceae is described from the Bhatkal Lateritic Plateau in Karnataka, India. It morphologically resembles F. pauciflora R.Br., but can be recognised by the well-developed ligulate leaves, membranous or subchartaceous glumes with 1-nerved keel, occurrence of 3 stamens, triquetrous nutlet with its prominent angles almost winged towards apex and subtruncate with a shallow depression at apex. Also, the epidermal cells on nutlet surface are transversely linear–oblong. A detailed description, distribution, phenology, images of the plant and its floral parts, and a comparison with related species are provided.
