(1071) Proposal to change the conserved type of Cactaceae, nom. cons., and the entries of the conserved names Mammillaria and Melocactus

Abstract

SummaryMottram, R.: (1071) Proposal to change the conserved type of Cactaceae, nom. cons., and the entries of the conserved names Mammillaria and Melocactus. — Taxon 42: 457–464. 1993. ‐ISSN 0040–0262.It is considered that the presently accepted type of Cactus, C. mammillaris, was an unsuitable choice, arbitrarily selected without due regard for the usage at the time of Linnaeus and for at least 150 years post‐Linnaeus. It is proposed that the type of Cactus be Cactus melocactus Linnaeus (Melocactus communis). To achieve this, the family name Cactaceae, already conserved, must be listed with a different conserved type.
