About Erythranthe suksdorfii (A.Gray) N.S.Fraga
Erythranthe suksdorfii is an annual dicot herb. It grows to a height of 3 to 10 centimeters (1.2 to 3.9 inches). Its leaves are opposite, slender, tapered, hairy, and generally sessile. The calyx is mildly hairy. The plant's petals are yellow, with red spots extending from the throat of the corolla to the lower corolla lobe. The corolla lobe is only 4–6.5 millimeters (0.16–0.26 inches) long. Flowering occurs from mid-April to July, varying by location. This species is native to Washington, Oregon, California, Idaho, Montana, Wyoming, Colorado, Nevada, Utah, Arizona, and New Mexico. It grows in valleys and foothills of mountainous areas, at elevations ranging from 130 to 2,160 meters (430 to 7,090 feet). It grows well in spring-moist wetland-riparian areas, and in subalpine forests containing Yellow Pine, Red Fir, and/or Lodgepole Pine. It prefers well-drained soils. Human activity has severely impacted this species' range, and it holds the "sensitive" status from both the Bureau of Land Management and the United States Forest Service.
