[MAIPC] Cuscuta Id Please?

Tue Jul 31 05:49:59 PDT 2018

correct. Noxious is a regulatory term weighted in law - i.e. it is a legal term that dates to the earliest common laws of this land - for human health protection and animal health - and has nothing to do with native or invasive. It has everything to do with poisonous or 'harm' as in economic harm. As a term weighted in law, it does not work for environmental harm. That is why the invasive terminology came out in the first place to fill that gap. Some states have tried to make them synonymous, but it really does not work. Poisonous use to only mean ingested. not contact dermatitis - purists in legalize would argue that contact dermatitis is not a poisoning.. the organ is not poisoned only inflammed... ...... 

The word noxious was coined into regulations back when we were hand carding wool. hand picking cotton. Thistles are a noxious weed because they destroy the commodity making it unselleable. 

corn cockle became a noxious weed because the seeds come through in the small grain harvest and kill chickens. 

Noone knows why galega is noxious.. it probably is not - farmers feed it to their cows all the time, no other studies ever done except the one - which could easily have been the limitations and assumptions of the time back in the 1800's... early 1900's  but by making it noxious it is illegal to sell, propogate or trade in the united states, makes for a lucrative diabetes drug market for another country ..... 

terminology is meaningless anymore...unless your going to court and then it is the interpretation of the law under consideration . If you don't want a plant there, just call it a weed and get rid of it... - my take on it....

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.).

Yes, some of this nonsense goes back to the USDA weed manual (written for farmers by Clyde Reed in the 1950s I think) where native plants like Rhus, Asclepias, Vitis, Solidago, etc., are all listed as weeds to be destroyed.

Of course, as you say, it’s far worse when natural lands managers are the ones doing this!

Good point, Rod - I agree wholeheartedly!

I have heard of managers whacking, or almost whacking, plants that were or were very likely native species (dodder, Phragmites, a thistle, a climbing  Polygonum).

Hi all,

Again, a word of caution to not target native Dodder (Cuscuta spp.) species.  They are valuable native plants despite how they might appear to the subjective aesthetics of humans.  As with Best Management Practices regarding the control all non-native invasive plant species, a plant should not be removed/treated unless identification is 100% certain that it’s a non-native.

Delaware lists C. epilinum  on its weed list (attached). 

Thanks,

Hello Mike, et al. 

The dodder I collected at the Kane Natural Area (now mitigation bank) in Carlstadt about 10 yr ago was C. japonica. It has apparently not been seen again there, but who knows. We also found this in 2015 in the Berry's Creek study area not too far away. 

As I recall, the first specimen keyed out to C. umbrosa because japonica was not in the keys we had (the usual northeastern floras). There may be a more cosmopolitan Cuscuta key on the Web (?). 

If you have a putative umbrosa or japonica specimen, you could ask Mihai Costea <costea at wlu.ca> if he would be willing to look at it - he's a world class dodderologist. You will need a good flowering specimen. 

I would not be at all surprised to find C. japonica elsewhere in NJ. FYI, both our Meadowlands specimens had purplish stems rather than the usual doddery yellow or orange. 

Best, Erik

I may or may not just be adding confusion, but Erik Kiviat found an interesting dodder in the New Jersey Meadowlands about a decade ago.  I do not think it was persistent?

Cuscuta umbrosa 

The NJ Strike Team lists C. japonica as a "Watch" species.

I don't think Japanese dodder has been reported further north than South Carolina on the east coast so far (see  https://www.cabi.org/isc/datasheet/17116).  If you look at photos of it in CA, it covers entire shrubs and trees unlike the native dodders.  Otherwise it is hard to tell it apart from the native dodders as it sometimes doesn't flower and can only be distinguished using DNA analysis.

Does anyone know much about the distribution of Japanese dodder?  When in NJ a few years back, with a field biologist from the NYNJ Trail Conference, she indicated the Cuscuta we were seeing in a wetland area was invasive. I don't see this  very often but I did just spot it in Harriman State Park in NY this past week. Wishing I had taken a closer look.

Agreed, they're very, very difficult to identify to species (you need fruits and flowers and a very fine ruler!)

 It’s Cuscuta - a valuable native species.  Probably C. campestre.
