Basionym: Morrenia hassleriana Malme (1909a: 346) . Type : PARAGUAY . In saxosis prope Concepción , 14 January 1908, E . Hassler 10803 ( lectotype (here designated) G-barcode G00084459 !, duplicate S!). Note :— Since the species was described in honour of E . Hassler, we opted to choose the material collected by him as the lectotype of this name. In addition, there is some question about the second syntype : it was cited as Fiebrig 1404 in the protologue, but the specimen at G is clearly labelled as Fiebrig 1484 .
