Every now and then I come across a website that provides a search for plant ID by ticking the known characteristics, but then I lose my reference to the site. If anyone knows of such sites, could you post links here? They should not be too specific to a small region. The point is that they should not use a binary elimination process, where if you don't know the answer to the first question asked, you're out. It seems like such an obvious need - for instance, to look for plants with a certain unusual leaf shape. It should be easy. Search engine hits are for various reasons just frustrating (this was discussed at great length in the forum posting Using the Internet wisely to search for plants!) and seem even more so lately. If you want to discuss the reason for that, please do it in that thread. I'd like to see not too much discussion but some good links here. I'll start with one cited in the thread mentioned above: World Wide Flowering Plant Family Identification page.
