Spec. Nov. Regni Veg. 8: 70. 1910 . Lectotypus (in hoc loco designatus): PARAGUAY . Concepción : Caballero-cue ”, II.1908 -1909, Fiebrig, K. 5244 ( G [ G00094587 ]! [lf, fl]). Isolectotypi : ( G [ G00307098 ]! [lf, fl] , K [ K001050343 ]! [lf, fl] , M [ M0211667 ]! [lf, fl]) . Under B. marginatum var. praecox, HASSLER (1910: 68) accommodated the new forms paraguayense, argentinum , and fiebrigii based on the presence of glabrous staminal tubes. However, he did not designate a holotype for this variety. Types of the names of the three forms are syntypes of the variety. We choose the type of the form fiebrigii that allows a clear application of the name of this variety according to Hassler’s concept. The present lectotype , Fiebrig 5244, is also the holotype of B. marginatum f. fiebrigii and the lectotype of B. marginatum subsp. meridionale .
