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<mailto: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

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.
