PC Products




Note: Since April, 2017, all prices listed on this page are half what they have sold for in the past.  This is to keep prices as low as possible, and in response to the success we have had with the sales of Android apps.

Note: We are planning to adjust our prices in late October due to several factors, so if you are interested in these, you may wish to order before then.

PC Keys for Windows 98 or newer versions,  are available for each individual state and province named in the map above.  Each include all the native and naturalized vascular plants known in the state or province.  The list below gives the total number of species included for each; text information regarding varieties and subspecies is included for a majority of the species.  Note: all PC versions have been updated as of May, 2020, and the Pacific Northwest version was considerably revised as of June 23, 2020.

Keys to the Plant Families of the World:

Interactive keys to the world’s plant families are available as of August 19, 2009.  They are based on the Angiosperm Phylogeny Group (APG) classification, and were also included with the 4th Edition of Contemporary Plant Systematics, by Dennis W. Woodland, published in 2009 and now out of print.  The family keys may be purchased separately from us directly. We acknowledge the keys are somewhat out of date, but may be of use to some botanists.
