Note: Epling (in J. Bot. 67: 6. 1929) termed the Clifford sheet as “standard” but also noted a Kalm sheet in LINN, and Clayton material in BM. Shinners (in Sida 1: 80. 1962) regarded Epling as having chosen it as lectotype ( “… was designated lectotype by Epling … (phototype in Gray Herbarium examined)"). However, Epling’s standard specimens are not equivalent to types (see Jarvis & al. in Taxon 50: 508. 2001). Stearn’s choice of the Clifford plate predates Shinners’ acceptance of the Clifford sheet as the type.
