Man v. Plant Part 4

I decided to give some sprays a chance after realizing that pulling weeds would be a losing battle.  After spraying Bayer and Ortho branded sprays, most of the weeds have withered away.  However, the really annoying weed is standing strong.  I've been looking around online and can't seem to figure out what this weed is called.  One person suggested it was Cylindrica Imperata.  I see the resemblance, but it doesn't look exactly like it.

Any clue what this is?
