Violet in Manhattan

Great picture. I'm from New Jersey originally, and I would have called that flower a Violet, not a Johnny Jump-Up. The flower I learned to call "Johnny Jump-Up" has a multicolored blossom like a tiny pansy (not to be confused with violas, which are also like tiny pansies, but not as tiny as Johnny Jump-Ups).

Johnny Jump-up is a common name for Viola tricolor, basically a wild pansy. This looks like a common blue violet, although a white with blue veins morph occurs in many populations. A few zillion grow in my yard as pretty weeds.
Strikes me it doesn't take much nature to please city people,and one level, this disconnect is worrisome.

OK what have you sciBloggers done that prevents my browser from returning to the sciblogs last 24 hrs page by hitting my back button? All the pages are sporting the new Top Posts gadget. Does correlation equate to causation of annoyance in this case?
