Abstract

Anthurium is a highly diverse neotropical genus, in which many species remain undescribed. Here, we describe a new species of Anthurium (sect. Calomystrium, subsect. Rupicola) from Central Peru, which we name Anthurium huaytae. The species is also the first record for subsect. Rupicola for Peru. Anthurium huaytae resembles A. amnicola but differs by its epiphytic habit (vs. epipetric habit), white or light lavender spathe (vs. purple spathe), persistent cataphylls (vs. promptly deciduous cataphylls) and slimmer flowers in relation to its length (ratio 1:1.1) (vs. flowers with a length-width ratio of 2:3). We provide a description, photographs and the floral scent composition of the new species. In addition, an updated identification key including all the known species of Anthurium subsect. Rupicola is also provided.
