Is Annona lutescens a synonym of A. reticulata (Annonaceae)? Use of geometric morphometric and coloration data to solve this controversy
Background and Aims: Annona lutescens was described in 1914 as a new species from Guatemala. Further studies allowed to locate this taxon in Chiapas, Mexico. However, some authors consider it as a synonym of A. reticulata, a species of American origin that is widely cultivated in many parts of the w...

| description | Background and Aims: Annona lutescens was described in 1914 as a new species from Guatemala. Further studies allowed to locate this taxon in Chiapas, Mexico. However, some authors consider it as a synonym of A. reticulata, a species of American origin that is widely cultivated in many parts of the world. Leaf shape and fruit color are the original characters proposed to segregate these two species. The aim of this study was to evaluate whether both characters can be used to distinguish these taxa.Methods: Leaf shape was evaluated using a geometric morphometric approach. In addition, differences in fruit color and hypocotyl coloration of seedlings maintained in controlled environmental conditions were observed.Key results: The geometric morphometric analysis showed that the leaf shape of both species is very variable and that there is no significant difference between them. Fruit and hypocotyl coloration is specific to each species.Conclusions: It is suggested that A. lutescens should be treated as a synonym of A. reticulata until more evidence is obtained to clarify the relationships between them. |

Antecedentes y Objetivos: Annona lutescens fue descrita en 1914 como una especie nueva conocida únicamente de Guatemala. Estudios posteriores permitieron localizarla también en Chiapas, México. No obstante, algunos autores la consideran como un sinónimo de A. reticulata, una especie de origen americano que actualmente se cultiva en muchas partes del mundo. Los caracteres originales propuestos para separar estas dos especies son la forma de la hoja y el color del fruto. El objetivo de este trabajo fue evaluar si los caracteres anteriores son de utilidad para separar A. lutescens de A. reticulata.Métodos: Se evaluó la forma de la hoja por medio de análisis de morfología geométrica. También se observaron las diferencias en coloración del fruto y del hipocótilo de las plántulas que germinaron en condiciones ambientales controladas.Resultados clave: El análisis de morfometría geométrica indica que la forma de las hojas de estas dos annonas es muy variable y que no hay diferencias significativas entre ellas. El color del fruto y del hipocótilo es específico para cada taxon.Conclusiones: Se sugiere que por el momento, y en espera de más datos que clarifiquen las relaciones entre ellas, se trate a A. lutescens como sinónimo de A. reticulata.
