The identity of Zamia katzeriana and Z. verschaffeltii (Zamiaceae)

Brittonia volume 60, pages 38–48 (2008)Cite this article

Abstract

The morphological variation of recently described species (also the older taxa) of Zamia distributed within southeastern Mexico that have wide, coriaceous leaflets is analyzed. The complex is designated as the Z. katzeriana species complex in reference to an historic collection of this name, which is also the earliest named species in the complex. The complex consists of Z. cremnophila, Z. lacandona, Z. splendens and Z. purpurea. During the 1990’s, Z. splendens was separately synonymized under Z. katzeriana and Z. verschaffeltii, both collected in Mexico by German collectors during the 18th century, but the precise locality is unknown. Information concerning the incomplete holotype of Z. verschaffeltii is particularly ambiguous, and the possible type locality suggested by Schuster, Socorro, is imprecise, thus generating taxonomic confusion. Morphometric characterization and discriminant analysis of the contemporary and historic collections (i.e., Z. katzeriana and Z. verschaffeltii) included all the known populations (11) and individuals (115) of the complex throughout its range. The results show that Z. verschaffeltii is not morphometrically related to any of the species in the complex and that Z. splendens should be considered a synonym of Z. katzeriana.

Resumen

En este artículo se caracteriza la variación morfológica de las especies de un complejo de Zamia, que presentan folíolos anchos y coriáceos con distribución en el sureste de México, la mayoría de reciente descripción. El complejo es denominado Z. katzeriana, por una colección histórica de este nombre, y consiste de Z. cremnophila, Z. lacandona, Z. splendens y Z. purpurea. Zamia splendens fue sinonimizada separadamente bajo dos colecciones históricas Z. katzeriana y Z. verschaffeltii, de las cuales se desconoce con exactitud su lugar de procedencia, excepto que fueron colectadas en México por botánicos alemanes del siglo XVIII. La información, en especial sobre el holotipo incompleto de Z. verschaffeltii es muy ambigua y la posible localidad tipo mencionada por Schuster, Socorro, es imprecisa, lo cual ha generado confusiones taxonómicas. La caracterización de la variación morfométrica incluyó a todas las poblaciones (11) e individuos (115) conocidas actualmente para el complejo en todo su rango de distribución en México. El análisis discriminante incluyendo a las colecciones históricas, determina que Z. verschaffeltii no está relacionado morfométricamente con ninguna especie del complejo y Z. katzeriana está estrechamente correlacionada con Z. splendens.
