The grass family (Gramineae) with approximately 10,000 species and 660 genera is the most ecologically and economically important of all plant families.
The herbarium collection of the Royal Botanic Gardens, Kew contains approximately 350,000 specimens (including 11,000 types) from all over the world. The United Kingdom, Middle East, Old and New World Tropics are particularly well represented.
A review of the whole family to generic level, including a system
of classification, can be found in the publication Genera Graminum
(1989) ISBN 0112500064.
The World Grasses Database provides computerised character information for 90% of the World's grass species with work ongoing to complete the remainder.
Within the herbarium the grass section comprises 8 staff who undertake research projects in a variety of areas.
