14. Bombax marginatum var. praecox Hassl. in Repert. 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 .
