Because Alan had the relationship as "?", we do not know whether or not
(in the range of Alan's flora) I.p. var emarginata sec Weakley < I.p.
brasiliensis sec USDA. Thus, a determination to ssp brasiliensis is
indeterminant (ambiguous in our terminology) as to whether it belongs
var emarinata. Given Alan recognizes only one taxon in the region and
recognizes only one, it seems to me a no-brainer that the correct
relationship should be =, with the caveat that this is a
relationship and might not always apply elsewhere in the world. I am
sure at what point Alan started being careful to make his concept maps
region specific rather than global, but perhaps after he handled I.c.
I note that the Carteret County record for I.p. shows up for the ssp
not for the full species. This is an error which I will ask Xianhua to
log as a bug and eventually look into.

Hmmm. I do not know why this is showing up as wimpy pink. We have
specimens: one is a photograph, then Matt Windsor collected the dead

The confusion MAY come in the var. emarginata / ssp. brasiliensis .
had it as var. emarginata, but SPECIFY insists on putting it as ssp.
In Alan's flora he has I. P-c. var. emarginata as ? synonym with ssp.
This clarifies nothing I realize.
On a brighter note, Laura Cotterman is sending stuff about Eupatorium
paludicola to UNC Press Office today. She just called to ask
IS an Herbarium Associate?" I had to admit that it just means that
you a key. And let you treat us to lunch frequently.

I see that the collections of Ipomoea pes-caprae from Carteret Co.
"ambiguous specimens." Am I correct that ambiguity refers to
