Potentilla rhyolitica
Potentilla rhyolitica is a species of flowering plant in the rose family, Rosaceae. Its two varieties, P. rhyolitica var. rhyolitica and P. rhyolitica var. chiricahuensis, are known by the common names Huachuca cinquefoil and Chiricahua cinquefoil, respectively. Both varieties are endemic to southern Arizona, where they grow at high elevations in the Madrean Sky Islands. In part because of its limited distribution, P. rhyolitica is considered an imperiled species, and P. rhyolitica var. chiricahuensis is critically imperiled.
Both varieties of Potentilla rhyolitica are endemic to the Madrean Sky Islands in Arizona. The isolation of high-elevation Potentilla populations by surrounding dry lowlands has contributed to evolutionary radiation, giving rise to several closely related species in the southwestern United States and Mexico, many with narrow distributional ranges.
