An unusual new record of Baccharis (Asteraceae) from the Peruvian Andes and its relation with the northern limit of the dry puna
Background and Aims: The knowledge of the richness and distribution of the flora in the Peruvian Andes is scarce; about 70 taxonomic novelties have been reported for this area in the last decade, a large part belonging to the Asteraceae.

| description | Background and Aims: The knowledge of the richness and distribution of the flora in the Peruvian Andes is scarce; about 70 taxonomic novelties have been reported for this area in the last decade, a large part belonging to the Asteraceae. The objective of this paper is to contribute to the knowledge of this flora through a new record of Baccharis acaulis. In addition, the distribution pattern of this species is examined.Methods: As part of floristic inventories in the high Andes of Peru, various field trips were carried out, several plant specimens were collected, among them a previously unreported species, which was identified by consulting some specialists and confirmed using taxonomic keys. Furthermore, predicting species distribution based on ecological niche modeling was made use the machine learning algorithm Maxent with the bioclimatic variables of the WorldClim database.Key results: A species of the genus Baccharis was registered for the first time for the flora of Peru. This species is recognized for its unique habit; it is a rhizomatous herb in which the aboveground part consists of small leaf rosettes surrounding a solitary capitulum. The species was collected in the south of the Peruvian Andes. This record extends the known distribution of the species considerably to the north.Conclusions: This record suggests the need to continue studying the Andean flora, as well as the links of their distribution patterns with the phytogeographical regions. |

Antecedentes y Objetivos: El conocimiento de la riqueza y distribución de la flora en los Andes peruanos es escaso; en la última década han habido alrededor de 70 novedades taxonómicas para esta área, siendo la familia Asteraceae la de mayor aporte. El objetivo de este trabajo es contribuir al conocimiento de esta flora, a través de un nuevo registro de Baccharis acaulis. Además, se examina su patrón de distribución. Métodos: Como parte de los inventarios florísticos en los altos Andes del Perú, se realizaron numerosos viajes de campo, se recolectaron varios especímenes de plantas, entre ellos una especie no reportada previamente, que se identificó mediante la consulta a algunos especialistas y se confirmó utilizando claves taxonómicas. Además, se predijo la distribución de la especie basada en modelos de nichos ecológicos, utilizando el algoritmo de aprendizaje automático Maxent con las variables bioclimáticas de la base de datos WorldClim.Resultados clave: Se registró por primera vez para la flora del Perú una especie del género Baccharis. Esta especie se distingue por su singular hábito, es una hierba rizomatoza en la que la parte superficial consiste en pequeñas rosetas de hojas que rodean a un capítulo solitario. La especie fue recolectada al sur de los Andes peruanos. El registro extiende la distribución conocida de la especie a una zona más norteña.Conclusiones: Este registro sugiere la necesidad de continuar estudiando la flora andina, así como los vínculos de sus patrones de distribución con las regiones fitogeográficas.
