Abstract

Our recent herbarium work yielded various undescribed species in the genus Aniba Aubl. (Lauraceae); four of them are described here. Aniba fasciculiflora R. Ortiz & van der Werff, A. sanchezvegae R. Ortiz & van der Werff, and A. tunquiana R. Ortiz & van der Werff are from northern Peru, and A. villosior R. Ortiz & van der Werff is from central Bolivia. The new species are compared with morphologically similar species and distinguished from them by unique combinations of characters, of which the most relevant are flower arrangement, flower shape, and stamen features. We reinstate three taxa that were previously placed in synonymy: A. gigantifolia O. C. Schmidt, A. murcana C. K. Allen, and A. simulans C. K. Allen. We also investigate stamen diversity in Aniba and explore its usefulness in distinguishing species in the genus. By their type of stamen, the newly described and reinstated species all belong to the Aniba affinis group.
