Introduction

This package is generated from a DELTA database (Dallwitz (1980) and Dallwitz, Paine and Zurcher (1993, 1995, 2000). It comprises an interactive identification and information retrieval system using the program Intkey (running under MS-Windows), descriptions (as WWW pages), illustrations, references, and other subsidiary material.

This paper is one of a series (Aiken et al. 1996, 1998) which present floristic data on the flora of the Arctic Archipelago in the form of a computerized morphological database and illustrations that may be used in interactive identification and in information retrieval. The names used for taxa have been discussed with Dr Peter Ball, University of Toronto, and are in line with those proposed for the treatment of the Cyperaceae in the Flora of North America.

The geographical scope of this study includes the islands of Nunavut north of 55°N and the Northwest Territories. The mapping and morphological data are based largely on specimens in the National Herbarium of Canada (CAN) and the Department of Agriculture Herbarium, Ottawa (DAO). Indications of adjacent distributions are based on maps in Porsild (1957) and Porsild and Cody (1980). All names used in Porsild (1957), Polunin (1940), and Hultén (1968) are accounted for. Measurements are limited to the sizes of specimens found on the Arctic Archipelago but occasionally the heights of species that may have much taller plants further south are indicated.

In Intkey, the view of the data is restricted (by default) to the accepted species and subspecific taxa. To view all the taxa, press the toolbar button labeled ‘Include all the taxa’. Note that identification cannot be carried out when all the taxa are included, because some of the ‘rejected’ taxa lack full descriptions, and the genera cannot be separated from their component species. To restore the set of taxa suitable for identification, press the toolbar button labeled ‘Include accepted species and subspecific taxa’.
