Dorobaea linearifolia (Asteraceae, Senecioneae), a distinctive new species of the subtropical montane forests of central Peru

Dorobaea linearifolia Montesinos & Pruski (Asteraceae, Senecioneae) is described as a new species from the humid subtropical montane forests of central Peru, specifically from the eastern slopes of the Andes in the Huánuco Region. The species is distinguished by its narrowly linear to very narrowly oblanceolate leaves, solitary terminal capitula, and glabrous habit. Its morphological affinities are briefly discussed in comparison with allied taxa in Dorobaea and related genera, images and a table of main character differences are also added. A preliminary conservation assessment, following IUCN Red List criteria, suggests the species should be considered Endangered (EN) B1ab(iii) due to its restricted distribution and ongoing habitat degradation.
