Auckland: Magnolia Press, v. 490, n. 3, p. 298-300, 2021.1179-3155http://hdl.handle.net/11449/209274In the present communication, after checking fossil plant names in the International Fossil Plant Names Index (IFPNI 2014-onwards), the homonymy of two fossil and extant species names of Ocotea Aublet (1775: 780) has been detected and resolved. Ocotea alata van der Werff (1991: 416) (extant) is replaced by a new name O. loretensis nom. nov., because of the earlier homonym O. alata Givulescu (1975: 173) (fossil leaves), according to Article 53.1 of the ICN (Turland et al. 2018). Similarly, O. morona-santiagoensis nom. nov. is proposed to replace the later illegitimate homonym O. pilosa van der Werff (2020: 220) (extant) non O. pilosa Givulescu (1975: 172) (fossil leaves). An additional homonym was found in extant Litsea Lamarck (1792: 574) that is preoccupied by a fossil. However, since it is currently recognized as a taxonomic synonym of Litsea tomentosa Blume (1826: 566), there is no need to create a nomen novum for it.298-300engCarta10.11646/phytotaxa.490.3.9WOS:000631159900003
