|discussion=<p><i>Parrya nudicaulis</i> is the most variable species in the genus, especially in leaf shape, size, and margin, as well as in the presence versus absence of the extrafloral glands. Much of the confusion about its limits resulted from different emphases on various characters. For example, E. Hultén (1971), who recognized six subspecies, expanded the range of <i>P. nudicaulis</i> to extend from the Canadian arctic and Alaska into the Russian Far East, Siberia, Central Asia, China, and the Himalayas. Three of his four North American subspecies, sometimes growing together, are rather poorly defined morphologically and appear to have been based primarily on the degree of development of leaf teeth. By contrast, R. C. Rollins (1993) recognized a single polymorphic species that included the Utah-Wyoming endemic <i>P. rydbergii</i>. Within a given population of <i>P. nudicaulis</i>, one finds both glandular and eglandular plants with leaf margins entire or variously dentate. In my opinion, these variables alone are unreliable, and flower size, in combination with other characters, can give a better indication of taxon identity.</p>
