Popis: Abstract Asplenium pseudoangustum is a poorly understood species known from the Peruvian Amazon forests. Due to morphological similarities with A. angustum and A. serratum, the position of A. pseudoangustum among the called A. serratum complex was suggested. However, spore ornamentation and scales morphology indicate that A. pseudoangustum is more related to the species of the A. hastatum subclade. Here, we present a redescription for this species, including scales and spore morphology, and an updated distribution including records from Brazil and Colombia.
