|taxon = Melocactus caroli-linnaei |authority = N.P.Taylor }}Melocactus caroli-linnaei is a cactus (a member of the family Cactaceae) found in Jamaica. When mature it is columnar, up to {{convert|1|m|ft|abbr=on|1}} high. Like all species of Melocactus, it forms a "cephalium" when mature – a dense mass of areoles covered with wool and spines at the tip of the stem. Flowers are produced only from the cephalium.[1] The species was originally named Cactus melocactus by Carl Linnaeus in 1753. The genus Cactus was later split and the pre-Linnaean name Melocactus was used for melocacti. The rules of botanical nomenclature forbid the repetition of a genus name and a specific epithet, so the name "Melocactus melocactus" is not allowed. In 1991, Nigel Taylor gave the species its current name, Melocactus caroli-linnaei.[1] References1. ^1 {{Citation |last=Anderson |first=Edward F. |year=2001 |title=The Cactus Family |publication-place=Pentland, Oregon |publisher=Timber Press |isbn=978-0-88192-498-5 }}, pages=456–459 {{Taxonbar|from=Q1479825}}{{Cactus-stub}} 4 : Melocactus|Cacti of North America|Endemic flora of Jamaica|Plants described in 1753 |
