Mapping here is tentative; see notes under var. pyramidalis. The more definitive records (solid dots on map) come from B, who consulted with Wherry (1929-34, 1955). Other records are based on colls. examined by JC that are relatively short but with thick stems, broad subcordate leaves and large flowers; these include colls. at EKY from LAWR, MENI, PULA and WOLF.
