13. Bombax marginatum subsp. meridionale Hassl. in Repert. Spec. Nov. Regni Veg. 8: 69. 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]) .

HASSLER (1910: 69) described B. marginatum subsp. genuinum based on Hassler 8237 p.p. to accommodate the typical marginatum apart from B. marginatum subsp. meridionale . However, according to Art. 26.2 (ICBN-Melbourne), the name genuinum is a superfluous name for B. marginatum subsp. marginatum (Art. 52.1) that was automatically established (whether or not it appears in the publication in which taxa are created) when Hassler validly published the subspecies meridionale (Arts. 6.8, 26.3, and 32.3). The type of B. marginatum subsp. marginatum is a St.-Hilaire collection from Brazil.

Under B. marginatum subsp. meridionale, HASSLER (1910: 69-70) accommodated three new varieties: intermedium, arboreum, and praecox. However, he did not designate a holotype for subspecies meridionale. Types of the names published by him within meridionale (five forms and three varieties) are syntypes of this subspecies.

Based on Hassler’s diagnoses, two clear-cut characters were used to distinguish his two new subspecies: the indumentum of the ovaries and the indumentum of fruits. No fruits were found in Hassler’s collections for subspecies genuinum or meridionale. Nevertheless, the existence of tomentose ovaries can be seen in type specimens of the varieties. We choose the type of the form fiebrigii that allows a clear application of the name of this subspecies meridionale according to Hassler’s concept.

The present lectotype, Fiebrig 5244, is also the lectotype of B. marginatum var. praecox and the holotype of B. marginatum f. fiebrigii .
