Thank goodness I was alerted to this commenting period through an article in my Google News feed, or else I may have missed it.

Phyllanthus urinaria, or what I've come to know it as -- Chamber Bitter, is "cropping up" all over Hampton Roads.  This delicate, fern-like weed loves our warm summers, and it grows quite fast as a result.  The underside of the plant has loads of seeds.  And if not dealt with correctly, it can quickly overwhelm one's yard, and then the neighborhood!

The other missing species is the Albizia julibrissin, or Mimosa tree.  I thought it had been listed as an invasive species, so perhaps I missed it from the list.  Traveling along our interstates, one can see how it's beginning to insert itself in our woods along the shoulders of our highways.  It's quick to shoot up and shade other, more desirable tree saplings, but with its summer flowers and delicate leaf pattern, few are quick to remove them.
