Araujia hassleriana (Malme) Fontella & Goyder, comb. nov.

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 .
