Genera Pleurothallidinarum: an updated phylogenetic overview of Pleurothallidinae

“…If Acianthera is to be maintained in its currently most accepted, broad sense (Pridgeon 2005), then it includes the generic concepts of Arthrosia, Brenesia, Cryptophoranthus, and Sarracenella, as proposed by and Chiron & van den Berg (2012). Nevertheless, it should also include Aberrantia, as suggested by Luer (2004) and proposed by Bogarín et al (2008), Antilla, as shown by Stenzel (2004), Apoda-prorepentia, as shown by Stenzel (2004) and Karremans & Rincón-González (2015), Didactylus, as suggested by Luer (2004), Ogygia, as proposed by Solano-Gómez (2003;, Pleurobotryum, as shown by Chiron et al (2012), Proctoria, as suggested by Luer (2006), and Unguella, as suggested by Luer (2004). To my knowledge, there are no DNA data available (published or unpublished) of species belonging to the monospecific genera Ogygia and Proctoria that can confirm their exact phylogenetic relationships.…”

“…Not surprisingly, subsequent phylogenetic studies within the Pleurothallidinae have shown that the generic, subgeneric and sectional systematics of the subtribe were not fully resolved. Recircumscriptions and emendations were either made or at least suggested by several authors who used novel analytical methods and/or included a broader sampling of species (Stenzel 2004, Abele 2007, Karremans 2010, 2014, Chiron et al 2012, Karremans et al 2013a, 2013b, Wilson et al 2013, Karremans & Rincón-González 2015, Chiron et al 2016. Meanwhile, hundreds of species' names, either new species or combinations, and dozens of new genera have since then been proposed by Luer (2002aLuer ( , 2004Luer ( , 2005Luer ( , 2006Luer ( , 2007Luer ( , 2009) and others, mostly but not exclusively, on the basis of morphology.…”

“…The proposed affinities are Acianthera (Ac), Dilomilis (Di), Lepanthes (Le), Masdevallia (Ma), Octomeria (Oc), Phloeophila (Ph), Pleurothallis (Pl), Restrepia (Re) and Specklinia (Sp); the oldest generic name is used here for the species within those clades (except Pleurothallis). This phylogenetic arrangement of the subtribe, despite taking only DNAbased studies into consideration , Stenzel 2004, Solano-Gómez 2005, Matuszkiewicz & Tukallo 2006, Abele 2007, Forster 2007, Meyer & Cameron 2009, Karremans 2010, 2014, Endara 2011, Bogarín et al 2013, Chiron et al 2012, Karremans et al 2013a, 2013b, Wilson et al 2013, in press, Pessoa et al 2014, Karremans & Rincón-González 2015, McDaniel & Cameron 2015, Chiron et al 2016 *At the time of preparation of this manuscript the total species number for genus Masdevallia had not been revised thoroughly. **The number of species attributed to Pleurothallis excludes those names that have not been placed elsewhere but most like do not belong in the genus.…”

“…The generic placement of this species needs to be reevaluated since molecular studies have produced two different, contradictory hypotheses; either this species is embedded in an Anathallis clade (Chiron et al, 2012) Epiphytic, humicolous or subterrestrial herbs; caespitose to long-creeping; erect or prostrate to climbing or sometimes pendulous, occasionally tuft forming. Rhizomes erect or creeping, simple or branched; internodes often abbreviated or more commonly elongated between the stems, covered with a few tubular sheaths, glabrous or verruculose, sheaths usually mucronate.…”
