Filogenia de Lysiloma (Fabaceae), un género restringido a Megaméxico con especies atípicas en las Antillas y Florida

Abstract: Antecedentes y Objetivos: Lysiloma es un género neotropical de la familia Fabaceae que comprende ocho especies, seis de las cuales se distribuyen ampliamente en México y dos más que ocurren en las Antillas y La Florida. Lysiloma es frecuente en los bosques secos de Megaméxico. Un estudio filogenético previo incluyó tres especies de Lysiloma y Hesperalbizia occidentalis. Ambos géneros están estrechamente relacionados, pero su divergencia tiene un apoyo débil. Nuestros objetivos fueron probar la monofilia del gé… Show more

“…Our analyses also confirm that the monotypic genus Hesperalbizia : H. occidentalis (Brandegee) Barneby & J.W. Grimes is sister to Lysiloma , in the Cojoba clade (sensu Koenen et al 2020 ), unrelated to either New World Albizia (clade D) or Old World Albizia (clade F), as previously shown by Duno de Stefano et al (2021) . Furthermore, Pseudosamanea guachapele (Kunth) Harms (previously Albizia guachapele (Kunth) Dugand in Rico Arce et al (2008) ) is also unrelated to New World Albizia but is instead a member of clade E, sister to clade F which includes Enterolobium , Samanea and Old World Albizia .…”

“…Two neotropical species, included in Albizia by Rico Arce et al (2008) are also placed outside New World Albizia (Fig. 3 ): Hesperalbizia occidentalis is closely related to Lysiloma , in agreement with previous results ( Iganci et al 2015 ; Duno de Stefano et al 2021 ); similarly, Pseudosamanea guachapele , is also placed outside Albizia in our phylogeny, emerging, as expected, together with the other species Pseudosamanea cubana (Britton & Rose) Barneby & J.W. Grimes, although relationships within this clade are unresolved (Fig.…”

“…Thirty-two sequences were newly generated for this study, while 31 sequences were obtained from GenBank ( www.ncbi.nlm.nih.gov/genbank ); most of the latter were generated for the studies of Miller and Bayer (2001) , Miller et al (2003) , Brown et al (2008) and Duno de Stefano et al (2021) . The ETS dataset consisted of 34 sequences (21 new) from 33 species; the ITS dataset consisted of 29 (11 new) sequences from 30 species.…”
