Has anyone invested in the Flora ID Northwest software, from what I can see from the following links, it looks like a great idea and resource.
Flora ID Northwest: computerized plant keys contain complete descriptive information for all vascular plant species known to grow in British Columbia and the Pacific Northwest (both native and naturalized introduced species).
There are 3 editions:
British Columbia Edition CD: $ 75
Southwest Canada Edition CD: $150 (New: BC, AB, SK, MB)
Pacific Northwest Edition CD: $150 (Revised: BC, AB, WA, OR, ID)
