Flowering Plants: Descriptions, Illustrations, Identification, and Information Retrieval.

This package incorporates the classification of Flowering Plant Families presented by The Angiosperm Phylogeny Group (APG) in Ann. Missouri Bot. Gard. 85, 531- 553 (1998). Their classification into ordinal and (informal) supra-ordinal groups reflects recent, far reaching molecular phylogenetic studies. It has appeared without group descriptions, but inclusion in our package makes it easily accessible (along with earlier, comprehensive schemes) for detailed research into morphological phytochemical, etc., character state correlations, and for preparing comparative group descriptions, via our family descriptions in association with Intkey and other DELTA facilities. This package is generated from a DELTA database Dallwitz 1980; Dallwitz, Paine, and Zurcher 1993). It comprises an interactive system for identification and information retrieval using the program Intkey (Dallwitz, Paine, and Zurcher 1995, 2000) (running under MS-Windows 95/NT or later), descriptions, illustrations, references, and other subsidiary material. The reasons for preparing these automated descriptions of Angiosperm families, the intended applications for which the database was designed, and the rationale for the manner of its construction, were set out in detail when it was first released (Watson and Dallwitz 1991). The information for this metadata was obtained from pages at http://www.biologie.uni-hamburg.de/b-online/delta/angio/
