Mimulus suksdorfii

Erythranthe suksdorfii. Synonym: Mimulus suksdorfii. (Suksdorf's Monkeyflower)
Phrymaceae (Lopseed Family)
Synonym: Scrophulariaceae

Semi-desert, foothills, montane, subalpine. Openings, shrublands, woodlands. Spring.
Near Hovenweep National Monument, Utah, April 18, 2010.

This Monkey flower is uncommon in western Colorado and New Mexico and more common in western Utah and Arizona.  It is quite minute, ranging from 1-7 centimeters tall and is thus quite difficult to spot from the height of a human.  It is made a bit easier to find by its bright yellow flowers.

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".

This plant was named by Asa Gray in 1886 from a specimen collected in Washington in 1885 by Wilhelm Suksdorf (1850-1932, Gray's respected collector in Washington). (Click for more biographical information about Suksdorf).

Erythranthe is from Greek "erythros", red, and "anthos", flower.

Genetic research has shown that Mimulus belongs in the Lopseed Family (Phrymaceae), not in the Snapdragon Family (Scrophulariaceae).

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