Discussion

Sibbaldia procumbens is circumpolar and is common from southern Greenland (to near 72° N) to the Aleutian Islands (to 166° W) of westernmost Alaska. It ranges southward in the Coast Ranges to the Siskiyou-Trinity Mountains, as well as Lassen Peak and Mt. Shasta of northern California, and farther inland to the Sierra-Cascade axis as far south as the San Bernardino Mountains of southern California, isolated mountain ranges in the central Great Basin, down the Rocky Mountains to the San Francisco Peaks in Arizona, and to the Sangre de Cristo Mountains of northern New Mexico. Farther south it reaches an elevation of more than 4200 m in the state of México. In eastern Canada and the northeastern United States, it is known from Labrador, the Long Range Mountains of Newfoundland, the Shickshock Mountains of the Gaspé, Quebec, and the White Mountains of New Hampshire.
