Abstract:

There have been many questions in recent years about Coryphantha vivipara (= Escobaria vivpara) and C. missouriensis (=E. missouriensis) in Idaho. The UBC collection (Accession No. V167955; Fred Fodor s.n.) is one of the few Idaho records. According to Flora of North America (2003), both species are erroneously reported from Idaho, and are actually Pediocactus simpsonii (though a few on the western border near the junction with Oregon and Washington are P. nigrispinus). <br> Pediocactus simpsonii is more than one species, even after P. nigrispinus is removed. Curtis Bjork has been studying this for a couple years now. The populations in east-central Idaho and adjacent Montana are probably not typical P. simpsonii (the type came from Utah). He hasn't firmly decided that yet, partly because there's a lot to wade through in the work Hochstätter. The annotation to the UBC specimen might not be the last. <br> The Fodor s.n. specimen is now annotated to Pediocactus simpsonii.
