Book Recommendations for Budding Botanists
The list below is intended for someone eager to learn the plants of region (especially for a job where identification is required). They are listed by type and in order of recommendation.
In most cases more than one taxonomic key can greatly ease identification and minimize frustration. Different keys emphasize different characteristics. The smaller the focus of the key (region, habitat type, plant type) the more specific the description and generally the easier to key a plant.
The above said, the on-line version of the Michigan Flora is an excellent resource once you become familiar with using it.
