climbing dayflower, Commelina diffusa

Yesterdays Carolina horse-nettle for some reason reminded me of Carolina dayflower. So I thought I might talk about naming errors. Whatever name a plant is first given, it sticks even if based on a mistake. Carolina dayflower, Commelina caroliniana, was named for the American Carolinas in 1788, where the first specimen came from. It wasn't until 1989 that botanists realized this is an Indian native. These things happened every once in a while. For instance spotted touch-me-not, Impatiens capensis, does not come from the region of the Cape of Good Hope. So I went to my image of Carolina dayflower and found yet another mistake. That was my original identification for this, later corrected to climbing dayflower. But I had never removed it from my index. Climbing dayflower grows in AL, AR, DE, FL, GA, HI, IL, IN. KS, KY, LA, MD, MO, NC, NJ, NY, OH, OK, PA, SC, TN, TX, VA, VT, WV, tropical America, Africa, Asia, and the Pacific Islands. Polk Co FL, 10/21/15.
