Although the test of time has long proved the value of the Moss Flora of North America as a necessary resource in any bryological laboratory, the three volumes are costly, voluminous, and often of two broad a scope for the requirements of local use. In the New England spirit of frugality, this new publication by Mr. Lauren D. Howard provides a regional abstract of Grout's flora with shortened keys and descriptions; an added, extensive glossary; and a most welcome, updated nomenclature. It should prove especially useful in classrooms where its convenient size and price will allow each student, in effect, to own a part of a classic of North American botany. ...

Welcome to Online Taxonomic Keys, a joint project of Fisheries and Oceans Canada and the Royal BC Museum. This project seeks to facilitate the development of, and make readily available, a variety of regional and global identification keys in a format that is concise and easy to use. The information presented is compiled from published and unpublished works from taxonomic specialists worldwide. Taxonomic keys are important tools used by scientists and other investigators to identify specific organisms based on defining characteristics. Up until the last decade, these keys were most often published as dichotomous keys, in which specimens are identified by choosing from a progressive series of pairs of options until a solution is reached. While dichotomous keys are still universally used, the online arena provides the opportunity to design and use keys based on a character matrix. The identification keys on this site are based on a character matrix format. Specimens may be identified by selecting one or more character states (columns) for each character (rows). As selections are made a list of possible species identifications will appear at the bottom of the matrix. Clicking on the species name opens an information sheet with more information to help you understand the specimen you’ve identified. This library of identification keys is a work in progress, and will grow and expand as new keys become available. ... [Information of the supplier]
This is an identification program for wildflowers in the northeastern and north-central parts of United States and adjacent Canada (if you live on the West Coast, try Reny's Wildflowers). Fill out the form as best as you can and you'll find which wildflowers match. It's better to start with a few characteristics you are sure about, then add more as needed. Use the "Back" button to go back and add (or subtract) characteristics. If you want to see all the flowers in the database, simply hit "Identify" without checking any boxes. ...
