Anthurium carrasquillanum (Araceae), a new species of section Decurrentia from Panama

摘要

Anthurium Schott (1829: 828) is a monophyletic and neotropical genus, which is present from Mexico to Argentina (Croat 1986, Carlsen & Croat 2013). The genus is estimated by ca. 1500 species in the Neotropics (Boyce & Croat 2012), including 250 that are present in Central America, where the greatest diversity is found in Panama and Costa Rica (Croat 1986). In the Revision of Anthurium for Panama (Croat 1986), 16 sections are recognized. Croat et al. (2005) described a new section of the genus, called Decurrentia Croat (2005: 14), which includes A. decurrens Poeppig & Endlicher (1845: 83) and A. pittieri Engler (1898: 372). The latter species are present in Panama and Costa Rica (Croat 1986) and were previously classified within Section Oxycarpium Schott (1860: 450) based on the work of Schott (1860) and Engler (1905). The Decurrentia section is mainly characterized by short internodes, elongate petioles and epunctate leaf blades with an acute base. There are currently 46 species in section Decurrentia but some of the species are as yet unpublished.
