EVOLUTION AND RELATIONSHIPS OF NORTH AMERICAN PEDICULARIS RUSTS AND THEIR HOSTS
The nearctic rusts of Pedicularis are not closely related to Puccinia lapponica and P. pedicularis of Europe. P. rufescens of the southern Cordillera consists of 2 newly recognized varieties: var. rufescens on Ped. canadensis, centranthera and semibarbata; and var. densiflorae on Ped. densiflora. P....
