Name: Evan Pioneer Valley south, MA, USA (Zone 6a)
Kew's World Checklist (the referenced database used by the COL and The Plant List) notes Plerandra elegantissima as the accepted name. http://apps.kew.org/wcsp/qsear...
It looks like this is a fairly recent change, Brittonia 65: 49 (2013). Two of the three authors are the ones who placed S. elegantissima as accepted, Baileya 23: 9 (1989). http://apps.kew.org/wcsp/qsear...
