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).
