• Resumen

  • Vanilla yanesha Damián, a new orchid species from Pasco, Peru is proposed. It is similar in overall morphology to V. mexicana Mill. However, V. yanesha is distinguished from the latter by its larger leaves, shorter inflorescence and labellum with a rounded middle lobe with 5 – 7 low, brownish keels. A line drawing and habitat information are provided as well as a comparison with morphologically similar species including a key to the Peruvian membranaceous-leaved species.
