[MAIPC] Cuscuta Id Please?

Rod,
To back up what you're saying, Maryland lists all dodders (Cuscuta spp.)
under its noxious weed seed regulations (COMAR 15.08.01.05:
http://www.dsd.state.md.us/comar/comarhtml/15/15.08.01.05.htm). Also,
other natives are included in this COMAR section -- wild onion (Allium
canadense), horse nettle (Solanum carolinense) and cocklebur (Xanthium
strumarium).
The noxious weed regulations (COMAR 15.08.02.04:
http://www.dsd.state.md.us/comar/comarhtml/15/15.08.02.04.htm) list
"poison ivy or poison oak (Rhus spp.)" and nimblewill (Muhlenbergia
schreberi). Plus this COMAR section doesn't distinguish between native
and non-native species when it lists nutsedge (Cyperus spp.) and foxtail
(Setaria spp.).
