However each user must have appropriate privileges on the underlying object in order to use the synonym. Public synonyms are accessible to all users. Specify PUBLIC to create a public synonym. Restriction on Replacing a SynonymВ You cannot use the OR REPLACE clause for a type synonym that has any dependent tables or dependent valid user-defined object types. Use this clause to change the definition of an existing synonym without first dropping it. Specify OR REPLACE to re-create the synonym if it already exists. To create a PUBLIC synonym, you must have the CREATE PUBLIC SYNONYM system privilege.Дescription of the illustration create_synonym.gif To create a private synonym in another user's schema, you must have the CREATE ANY SYNONYM system privilege. To create a private synonym in your own schema, you must have the CREATE SYNONYM system privilege. Work down the taxonomic hierarchy from Major Group (to find out which Families belong to each), to Family (to discover the Genera belonging to each) and finally Genus (to list the Species in each).See Also: Oracle Database Concepts for general information on synonyms Conifers, cycads and allies Gymnosperms.The status of the 1,064,035 species names, are as follows:Д¬lick on the major plant group of interest to explore the taxonomic hierarchy embedded within The Plant List. The Plant List contains 642 plant families and 17,020 plant genera. Of these 350,699 are accepted species names. The Plant List includes 1,064,035 scientific plant names of species rank. Important limitations are summarised here. Our aims remain to produce a вЂbest effortвЂ™ list, to demonstrate progress and to stimulate further work. The Plant List is not perfect and represents work in progress. Around 20% of names are unresolved indicating that the data sources included provided no evidence or view as to whether the name should be treated as accepted or not, or there were conflicting opinions that could not be readily resolved. The Plant List provides the Accepted Latin name for most species, with links to all Synonyms by which that species has been known. The differences between versions are summarised here. Version 1.1 includes new data sets, updated versions of the original data sets and improved algorithms to resolve logical conflicts between those data sets. Version 1.1 (September 2013) replaces Version 1.0 which remains accessible here. It aims to be comprehensive for species of Vascular plant (flowering plants, conifers, ferns and their allies) and of Bryophytes (mosses and liverworts).Д¬ollaboration between the Royal Botanic Gardens, Kew and Missouri Botanical Garden enabled the creation of The Plant List by combining multiple checklist data sets held by these institutions and other collaborators. The Plant List is a working list of all known plant species. WFO welcomes feedback from users for improvements to its Taxonomic Backbone which is curated by a growing community of WFO Taxonomic Expert Networks (TENs). TPL has been static since 2013, but was used as the starting point for the Taxonomic Backbone of the World Flora Online (WFO), and updated information can be found at WFO is being developed by a consortium of leading botanical institutions worldwide in response to the 2011-2020 GSPCвЂ™s updated Target 1: to achieve an online Flora of all known plants by 2020.

The Plant List (TPL) was a working list of all known plant species produced by the botanical community in response to Target 1 of the 2002-2010 Global Strategy for Plant Conservation (GSPC).
