I have been asked this question in various forms and have yet to find a good list of trees for all of North America. Sometimes regional lists are available. What I am looking for is a comprehensive list of trees in North America, (and by North America i mean all of the continent, not just the east coast of the US.), hopefully something in a format that is searchable by different identifiers. Books, websites, or personal knowledge are all welcome answers.
Yes, Ron. I was asked this by our office manager and thought about it for a minute, did a little research, and realized that I couldn't come up with a decent answer. I can probably come up with a quick list off the top of my head of quite a few trees with palmate leaves, but I've never seen a comprehensive list of trees like this. In this day and age, it seems that there should be a searchable list where one could enter qualifiers like "palmate leaves" and have an answer in a few moments. I bet if I could pick your brain, you've probably got that list rattling around in the little grey cells, no?
Just google it. A simple request like "tree palmate leaves" produces lots of useful information. On the top is the site titled "Trees with palmate leaves": http://www.flowersofindia.net/treeid/palmate.html Couple pages down - "Advanced key - Rogers Trees and Shrubs". Checking "Palmate leaves" produces four pages of trees you need: http://www.rogerstreesandshrubs.com/gallery/chooser.asp
How do you define 'North America'? Including Mexico or not? If yes, down as far as Panama or not? Caribbean islands? And do you just want species native to the region, or introduced species as well? And what is your preferred definition of a tree?
Thanks - I hadn't seen the link to Rogers. It's pretty good but I am doubtful about it's comprehensiveness. Of the four pages given, most of them are Acer, which leads me to think that there might be many more trees not listed.
Canada, US, and Mexico. Hadn't thought about the Carribean - would classify the Carribean Islands with Central America. It's a good follow up question. There are somewhere between 100,000 and 250,000 different types of trees worldwide. I am really asking about the existence of a solid list of these. Those with Palmate leaves and within the geographic region of NA would be two filters for a search of this fantasy list. I can't off the top of my head think of a practical use for this, but I seem to be asked this kind of question a few times each year.
