The fastest way to look up a specific plant from this list is to go to the top of your browser and select Edit > Find (on This Page)... Ctrl+F. Then in the Find box, after 'Find what:' type the name you are searching for and click on 'Find Next'. If there is a matching entry on the page it will take you to it and it will be highlighted. Keep using 'Find Next' until the Finsihed searching the document box pops up.
This list is a work in progress. Where I have found details of harmful effects of the plants, they are included. The list will also eventually cross reference plants by both common and botanical names, which it does not do now.
