Phenology | Flowering Apr–Jun. | Flowering May–Jul. |
Habitat | Drained flats or slopes subject to vernal inundation, depressions in open fields, bare clay soils, vacant lots, roadsides. | Stream and lake sides, gravel bars, springs, moist slopes, damp swales between dunes, along trails. |
Elevation | 10–800 m. (0–2600 ft.) | 700–2300 m. (2300–7500 ft.) |

Discussion | The distinction between Erythranthe latidens and E. inflatula sometimes seems arbitrary, perhaps because of gene exchange where they are sympatric in northwestern California. Erythranthe latidens in Oregon is known only from southern Harney County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
