Cordillera : “In rupestribus Cordillera de Altos ”, II.1898 -1899, Hassler, E. 6031 ( G [ G00077086 ]! [lf, fl], G [ G00094589 ]! [lf, fl], G [ G00094590 ]! [lf, fl], G [ G00094591 ]!

[fl], S [ S10-34541 ]! [lf, fl] ). ROBYNS (1963: 79) designated Hassler 410 as holotype of Pachira marginata f. arborea , and this designation is correctable to lectotype (ICBN-Melbourne, Art. 9.9). The exact citation of P. marginata f. arborea in ROBYNS (1963: 77) is: “Pa. [ Pachira ] marginata f. arborea Chodat et Hassl. , loc. cit. [Bull. Herb. Boiss. ser. 2, V], p. 72 (1905)”. In the original publication, CHODAT (1904: 72) mentions in this place: Bombax marginatum K. Sch. [...] forma arborea ”. Furthermore P. marginata A. St. -Hil. & al. is the basionym of B. marginatum (A. St.-Hil. & al.) K. Schum. We consider then P. marginata f. arborea in ROBYNS (1963: 77 , 79) therefore to be a lapsus calami. We believe that Robyns intended B. marginatum f. arboreum , as did CHODAT (1904: 72) , since Robyns’ concept of Pachira included only P. aquatica Aubl. and P. insignis (Sw.) Savigny ( ROBYNS, 1963: 233 ). Robyns annotated 2 duplicates of Hassler 410 in G ([ G 00 307101], [ G00307102 ]) but he did not designate either one of them as the lectotype . In the sense of Art. 9.17 (ICBN- Melbourne) we complete herein Robyns’ typification by narrowing down his selection to the only duplicate with both leaves and flowers as lectotype . Under B. marginatum var. arboreum, HASSLER (1910: 70) described B. marginatum f. apaense ( holotype : Hassler 410 ) and B. marginatum f. rupestre ( holotype : Hassler 6031 ).
