GrassBase (or GrassBase – The Online World Grass Flora) is a web-based database of grasses, continually maintained and updated by the Royal Botanic Gardens, Kew.[1][2]

As of 2015, GrassBase was one of the largest (along with GrassWorld) structured datasets for plants.[2] In the January 2016 update, it had morphological descriptions for 11,369 accepted species of grasses and listings for 64,213 botanical names.[3]

Authorship of the database is credited to W. D. Clayton, M. S. Vorontsova, K. T. Harman and H. Williamson.[4]
