Thanks for the article. I really enjoyed it. I am saving it to my favorites for future reference. I wish the people who classify plants would stop switching them around as Sequoias, Coast Redwoods, Cryptomerias, Dawn Redwoods and Bald Cypresses all used to be in the Taxodiaceae family. I took three plant ID classes at a local community college and one of them was conifers. It is amazing how the families and names keep on changing.
