Note: Syntypes (with dates): 8 August (F, GH); 24 August (US!); Syntypes (dates unknown): (G , LE, MASS, MO, NY, P , UC, Z). MIN does not have any material of this number (A. F. Cholewa, pers. comm.). Heller did not cite a date. As we have not seen much of the syntype material and because this genus is currently under study by T. Lammers, who studied these collections and provided us with information, we are reluctant to select a lectotype.
