Which image to use?  That's a frequent morning puzzle here.  Who needs sudoku?  Here's the rejected choice.  And speaking of waifs and rejects.  Oliver Farwell collected a blue-eyed grass in 1896 at Belle Isle in the Detroit River.  That specimen is the only known example of Sisyrinchium hastile.  Students of the genus are still scratching their heads over just what that plant represents.  Some speculate that it is an atypical S. albidum.  The USDA website says S. albidum has been extirpated in MIchigan.  Farwell's species is the reason for that.  Typical S. albidum is quite common.
