So, about a year ago I heard about this Carex frankii lookalike that I had never heard of - Carex aureolensis. It apparently has relatively recently been split out from Carex frankii and is recognized as distinct on iNaturalist. See: http://thevasculum.blogspot.com/2010/08/carex-aureolensis_04.html?m=1
Since Franks sedge was one of the first Carex species I learned to sight ID, I just assumed it was more common. But literally every time I have found a specimen that I initially think is Frank’s sedge, it turns out to be C. aureolensis.
Now I’m doubting whether or not I’ve actually ever seen Frank’s sedge in real life in Texas.
But based on the greater amount of observations of the two species in Texas, my experience with C. aureolensis being more common seems to be abnormal. Or are they just chronically mixed up? A lot of the observations of C. frankii don’t seem to have sufficient data to distinguish the two, but I hesitate to down vote identifications since I’m not even sure I know what franks sedge looks like any more since I don’t think I’ve ever seen it.
Are there any Texas wetland people or Carex spp. gurus who can speak to this?
