Synopsis of the genus Axiniphyllum (Asteraceae, Millerieae) endemic to Mexico
Background and Aims: The genus Axiniphyllum is endemic to Mexico, distributed in the southern and western part of the country. Its members are characterized by its perennial herbaceous habit, opposite and lobulated leaves, basally connate, and 4-angulate cypselae lacking a pappus. The objective of t...

| description | Background and Aims: The genus Axiniphyllum is endemic to Mexico, distributed in the southern and western part of the country. Its members are characterized by its perennial herbaceous habit, opposite and lobulated leaves, basally connate, and 4-angulate cypselae lacking a pappus. The objective of this research was to perform a synopsis of the genus, including descriptions, a key for species identification, and a distribution map.Methods: Specimens of Axiniphyllum deposited in different Mexican herbaria were reviewed. Identification was carried out using taxonomic treatments and revision of type specimens.Key results: Species of Axiniphyllum can be recognized by the morphological variability of the leaves and the heads; A. pinnatisectum and A. sagittalobum display ligulated flowers. Description of each species was increased with respect to what has been previously reported in the literature due to the addition of new observations.Conclusions: Five species are recognized in Axiniphyllum; all species can be considered as rare because the scarcity of their collections. Some localities where they have been recorded are currently strongly affected by human activities. |

Antecedentes y Objetivos: El género Axiniphyllum es endémico de México con distribución en el sur y el occidente del país. Se caracteriza por su hábito herbáceo perenne, hojas opuestas y lobuladas, connatas en la base y cipselas 4-angulares, desprovistas de vilano. El objetivo del presente trabajo fue realizar una sinopsis del género, incluyendo descripciones, una clave para identificar sus especies y un mapa de su distribución geográfica.Métodos: Se revisaron ejemplares de Axiniphyllum depositados en distintos herbarios del país. La identificación se realizó con ayuda de tratamientos taxonómicos y revisión de ejemplares tipo.Resultados clave: Las especies de Axiniphyllum pueden reconocerse por la variabilidad morfológica de las hojas y las cabezuelas; A.pinnatisectum y A. sagittalobum presentan flores liguladas. La descripción de cada especie se incrementa con respecto a lo reportado previamente en la literatura debido a la adición de nuevas observaciones.Conclusiones: Se reconocen cinco especies en Axiniphyllum, las cuales pueden ser consideradas como raras, pues las recolectas realizadas para ellas son escasas. Algunas de las localidades donde se han recolectado se encuentran fuertemente afectadas por las actividades humanas.
