Guerrero, P.C. & Walter, H.E. 2019: Nomenclatural novelties and a new species in Chilean Cactaceae. – Phytotaxa 392(1): 89-92

The taxonomy of Chilean Cactaceae is notoriously difficult (see e.g., Duarte et al . 2014). Molecular data, and phylogenetic approaches, provided answer to better understand the natural classification of cacti (see e.g., Nyffeler 2002, Edwards 2005, Nyffeler & Eggli 2010, Ritz et al . 2012, Schlumpberger & Renner 2012, Larridon et al . 2015, 2018). As part of an ongoing revision of the Chilean Cacti, which is part of the “Modern Flora of Chile” initiative, nomenclatural novelties are needed in Eulychnia Philippi (1860: 23), Leucostele Backeberg (1953: 36) and Maihueniopsis Spegazzini (1925: 86) (Cactaceae Juss.).
