CRC World Dictionary of Grasses, 3 volumi

These pages bring together a great deal of otherwisedispersed data — information and morphological description regarding the genera and the species, their geographical distribution, distinctive characters, common and vernacular names, etc. This account is certainly not complete in itself, also because of the numerous nomenclatural and taxonomic problems encountered and the conflicting taxonomic treatments (see C.W. Hamilton and S.H. Reichard, Current practice in the use of subspecies, variety, and forma in the classification of wild plants. Taxon 41: 485-498. 1992), this will always be a work in progress and neverending. The study is based on secondary and primary data, and the information derives from several sources. It is gathered from a wide variety of electronic, print, and other sources, such as papers of general interest, reports and records, taxonomic revisions, field studies, herbaria and herbarium collections, notes, monographs, pamphlets, botanical literature and literature tout court, sources available at various natural history libraries, floras and standard flora works, local floras and local histories, nomenclatural histories, ICBN (W. Greuter et al. 2000: International Code of Botanical Nomenclature [Saint Louis Code] adopted by the Sixteenth International Botanical Congress St. Louis, Missouri, July/August 1999), ICNCP (International Code of Nomenclature for Cultivated Plants), International Union for Conservation of Nature and Natural Resources, IPNI. Also useful have been reference collections, botanical gardens and nurseries, dictionaries, drawings, poetry, journal articles, personal communications, biographies and scientific biographies, and the British Museum General Catalogue of Printed Books, the Royal Botanic Gardens Kew Library Catalogue on the World Wide Web, Manuel du Libraire et de l’Amateur de Livres (by Jacques-Charles Brunet), the Catalogue of Books, Manuscripts, Maps, and Drawings in the British Museum (Natural History), and the Catalogue of Botanical Books in the Collection of Rachel McMasters Miller Hunt, etc.
