Tree Identification
is a related identification program for 139 trees in the northeastern and north-central parts of North America.
The Key to World Wide Flowering Plant Family Identification
is a professionally developed key to plant families which works well, but may be difficult for amateurs to use.
MyWildflowers.com has an easy-to-use interface for Pennsylvania wildflowers.
The Pine Barrens Plant Identification Key is a primitive but interesting approach at a database-driven plant key.

Hi Tom,
This is basically a fan letter!
I'm a senior lecturer on the BSc(Hons) Herbal Medicine programme at Lincoln college in the UK and I've just discovered your book. I thought you might like to know that I've already added it to my recommended reading for new starters on the course (we take 25-30 entrants a year), and have put a link to it on our Facebook group for existing students. So you should be getting some more orders from the UK as it's going to be really useful for them. In fact, I already have a whole heap of course handouts that basically do the same as your book for each family: ie summarising main botanical features and discussing medicinal uses, major constituents and themes, with a few examples and a few pictures. So I'm overjoyed to find your book doing the same thing but on a bigger scale (albeit now also slightly cross with myself that I should have had the idea first and/or should have found your book earlier and saved myself a load of work doing the same thing!)
Regards,
Robyn James MNIMH
