Range Extensions for Orthotrichum lyellii, O. papillosum, and O. pylaisii, with Comments on Taxonomic Distinctions
Orthotrichum lyellii, O. papillosum, and O. pylaisii are reported new to Arizona based on specimens collected in Yavapai County. Orthotrichum lyellii is confirmed for Nevada from three counties along the California border. Orthotrichum papillosum also is confirmed from Nevada from one location near...
