[MAIPC] Fwd: Microstegium cutting

Wed Aug 29 10:11:55 PDT 2018

Wow! I didn't know about cleistogamous flowers in stilt grass.  Are they
ever below ground? How high on the stalk?   Are they visually different
from the ch flowers?  (anyone have a picture?)  And while we're on the
subject: does anyone know how long stilt grass seeds remain viable in the
seed bank?  This plant is a major challenge to restoration of the Drew U
Forest Preserve here in NJ.

Thanks,
Sara Webb
