Ramella, L., M. Soloaga & P. Perret (2014). Typifications of names published by E. Hassler and R. Chodat in the genus Dorstenia L. (Moraceae) of the flora of Paraguay. Candollea 69: 207–210. In Spanish, English and Spanish abstracts.
The authors typify 7 names in the genus Dorstenia L. published by Emil Hassler and Robert Chodat based on specimens collected in Paraguay. For each name, the typical material in accordance to the original descriptions and used by these authors is identified. A typographical error in the designation of the holotype of Dorstenia cayapia subf. lobata Hassl. is corrected. The prior lectotypification of Dorstenia cayapia f. paraguariensis Hassl. is narrowed down to a single specimen. Dorstenia brasiliensis var. guaranitica Chodat is a superfluous illegitimate name.
