A small population of a unique looking taxon was found on the Pacific coast of the Baja California peninsula, which is here presented as a new species.  Question and/or Hypothesis:  In the morphological analysis in the individuals of a putative new taxon, some peculiarities stand out, such as a suffruticose herbaceous perennial growth form with erect and compact branching, featuring a small cushion, unlike the rest of the known species, which are rather procumbent, or erect in form. It also has revolute leaf margins in the blade.  Studied Species: Nama asuncionensis sp. nov. (Namaceae) and morphologically similar species.  Study Site:  Central Pacific coast of Baja California, Mexico.  Method:  Through bibliographic consultation, review of herbarium specimens, and photographs, a comparative morphological analysis was carried out with other Nama species of the peninsula and mainland Mexico.  Results:  Based on the comparative analyses, Nama asuncionensis is here presented and illustrated as a new species.  Conclusions: Nama asuncionensis is a micro-endemic species restricted to the Pacific coastal environment of the peninsula. We propose that this new taxon be included in the Eunama section of the genus based on its morphological characteristics, including a membranous loculicidal dehiscent capsule, free styles, and sepals divided to the base. This taxon seems to be limited to a narrow coastal strip, with high relative humidity, where it develops its fresh leaves and flowers during the mild season.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen  Antecedentes:  Aunque la mayoría de los taxones de Nama habitan en sustratos arenosos, ninguno de ellos parece ser exclusivo del ambiente de dunas costeras. Se encontró una pequeña población de un taxón de aspecto único en la costa del Pacífico peninsular, que aquí se presenta como una nueva especie.  Pregunta y/o Hipótesis:  En el análisis morfológico de los individuos de un supuesto nuevo taxón, se distinguen algunas particularidades, tales como una forma sufrutescente de herbácea perenne con ramas erectas y compactas, semejando una pequeña almohadilla, a diferencia del resto de especies conocidas, que son más bien formas procumbentes o erectas. Tiene además hojas revolutas.  Especie de Estudio: Nama asuncionensis sp. nov. (Namaceae) y especies morfológicamente similares.  Sitio de Estudio:  Costa Pacífica Central de la Península de Baja California, México.  Método:  A través de bibliografía, revisión de ejemplares de herbario y fotografías, se realizó un análisis morfológico comparativo con otros taxones reconocidos que habitan en la Península de Baja California y México continental.  Resultados:  Basándose en los análisis comparativos, Nama asuncionensis se presenta e ilustra aquí como una nueva especie.  Conclusiones: Nama asuncionensis es una especie microendémica restringida al entorno costero del Pacífico peninsular. Proponemos que este nuevo taxón se incluya en la sección Eunama del género basándonos en sus características morfológicas, que incluyen una cápsula loculicida membranosa dehiscente, estilos libres y sépalos divididos hasta la base. Este taxón parece estar limitado a una estrecha franja costera, con alta humedad relativa, donde desarrolla sus hojas y flores durante la estación benigna.]]></p></abstract>
