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]

World Wide Web System of interlinked hypertext documents accessed over the Internet

The World Wide Web (WWW), commonly known as the Web, is an information system where documents and other web resources are identified by Uniform Resource Locators, which may be interlinked by hypertext, and are accessible over the Internet. The resources of the WWW may be accessed by users by a software application called a web browser.

Royal Botanic Gardens, Kew non-departmental public body in the UK

Royal Botanic Gardens, Kew is a non-departmental public body in the United Kingdom sponsored by the Department for Environment, Food and Rural Affairs. An internationally important botanical research and education institution, it employs 1,100 staff. Its board of trustees is chaired by Marcus Agius, a former chairman of Barclays.

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]

Botanical name scientific name for a plant (or alga or fungus) (ICNafp)

A botanical name is a formal scientific name conforming to the International Code of Nomenclature for algae, fungi, and plants (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the International Code of Nomenclature for Cultivated Plants (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups ."
