Ack - Invader!!!

I am currently at a meeting in Mystic, Connecticut, right near the very first place that the invasive plant Hydrilla verticillata was ever found in New England, in the late 1980s. It took people a few years after that discovery to figure out what they had, because the first samples taken were misidentified as a similar-looking species, Egeria densa.
