The grass genera of the world

Contents

The key and descriptions were generated from a DELTA database (Dallwitz 1980; Dallwitz, Paine, and Zurcher 1993).

Introduction

Interactive key, including interactive information retrieval

The interactive key allows free choice of characters, is easy to use, and can lead to correct identifications in spite of occasional errors. It can display all the illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa.

Character list • Implicit attributes

Classification

Species sampled for anatomy

Acknowledgements • References • Citation • Contacts, conditions of use, contributions

Descriptions

The bold parts in the descriptions are diagnostic descriptions, generated with the aid of Intkey (Dallwitz et al. 1993). They distinguish most taxa in at least two respects from the other taxa.

These descriptions are offered for casual browsing only. We strongly advise against extracting comparative information from them. This is much more easily achieved using the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting specified attributes, summaries of attributes within groups of taxa, geographical distribution, classification, and species sampled for anatomy.
