synonyms

The species, as described above, is diooica in the narrow interpretation, as is used for example, by Klenke & Scholler. At the other hand stand many authors who maintain a very broad concept of this species, encompassing aecia on a wide range of Asteraceae, and telia on all sorts of Carex. The following species described here fall, as varieties or mere synonyms, under this wide concept of dioicae: P. arenariicola, capillaris, caricis-frigidae, caricis-montanae, cirsii-sempervirentis, dioicae, extensicola, firma, jageana, linosyridis-caricis, petasites-pendulae, ptarmicae-caricis, rupestris, ruttneri, scabiosae-sempervirentis, schoeleriana, schroeteriana, senecionis-acutiformis, silvatica, tirolensis.
