Plant species of Tumamoc Hill

Tumamoc has more than 300 species of plants. Thanks to the artistry, hard work and generosity of T. Beth Kinsey, you can already see a few of them in this part of the website.

The species list has all our species but many do not yet have their own webpage. We are working to include them, too. (Check the What's new? page for notice of additions.)

Meanwhile, visit Beth's own site Fireflyforest where you will find other plants of southern Arizona, as well as many from Hawaii. And please do let Beth know how much you appreciate her work!
