Okay. First things first. Props to Ann Prescott. Fantastic field manual. The closest thing to a bible for a lot of us.
Excuses. Most pertinent here is distribution, ie., currently there is no possibility of a realistic form of access for a lot of people. The attempt here is by no means ideal. Okay. So that's all I'll say about it.
This is a searchable pdf scanned from a copy of Ann Prescotts' "It's Blue with Five Petals". Errors have been introduced to the text from the scanning process. I have only corrected the spelling of plant names. Searches conducted for phrases in the descriptions will thus likely fail.
Suggestions welcome in comments. Flames also welcome :)
