Below you will find links to comments & updates on three Colorado floras.

Floras are complex and very time consuming to write. They demand not only expertise in the plants of an area but also expertise in technical writing, logic, and scientific precision. Three floras of Colorado strive for these goals and achieve them to various degrees, but all three have room for improvement, especially in the construction of clear and accurate keys. Weber's flora has many helpful comments found nowhere else, but the keys are needlessly complex. Ackerfield's flora improves on Weber's but contains problems with conflicting nomenclature, poor photographs, and keys. Heil and O'Kane's flora is the best for the Four Corners region (and beyond) and has the great advantage of being put together by many experts, not just one author (as in Weber and Ackerfield's floras).

A Utah Flora by Welsh is often the flora I turn to for the best keys and most interesting and accurate comments.

Flora Neomexicana III by Allred is a very well researched flora that has good keys and very helpful line drawings.
