NEW LIVERWORT RECORDS FROM THE PERUVIAN ANDES

摘要

Enumeration and distributional data of 28 liverworts new to Peru are presented, accompanied by taxonomic annotations, phytogeographical evaluation and illustrations. Remarkable new Peruvian records include the very rare northern Andean endemic Platycaulis reni-folia as well as Frullania pearceana, hitherto known only from its type locality in Bolivia. Oil bodies are described for the first time in the genus Platycaulis and male branches are newly observed in Radula yanoella, a species hitherto knownonly in sterile state.
