This Monkey flower is thought to be uncommon in the Colorado Plateau region that this web site covers. It is quite a minute plant, ranging from 1-7 centimeters tall and is thus quite difficult to spot from the height of a human, which may be why it is thought to be uncommon. Perhaps it is there but unnoticed. Betty and I find it more and more often. Its attractive yellow flower is what catches our eyes -- when we are walking at a snail's pace.

Erythranthe suksdorfii is found from about 4,000 to 8,000 feet elevation, usually in exposed areas of sagebrush, Pinyon/Pine, and Ponderosa communities, and in Welsh's words, "often along windswept ridges", but all the photographs on this page show plants in sandy flatlands. We have found it, however, in far western San Juan National Forest in exactly Ponderosa communities.

This species was first named Mimulus suksdorfii by Asa Gray in 1886 from a specimen collected "on rocks Mount Paddo" in Washington in 1885 by Wilhelm Suksdorf (1850-1932, Gray's respected collector in Washington). (Click for more biographical information about Suksdorf).

Mimulus expert Guy Nesom and several co-authors published a rearrangement of the Mimulus genus, removing most species from Mimulus and placing them in Erythranthe. See also Nesom 2012.

Genetic research has shown that Erythranthe species belong in the Lopseed Family (Phrymaceae), not in the Snapdragon Family (Scrophulariaceae).
