Iliamna longisepala, known by the common name long sepal globemallow,[1] is a perennial plant species in the Malvaceae family.
Long haired perennial plant with 5-9 lobed leaves. Flowers in racemes that are pink to lavender.[2] The slightly longer sepal length distinguishes this species from similar looking species like the more common Iliamna rivularis and are around 1.5 cm long.[2]
This plant grows at lower elevations from sagebrush desert to Ponderosa pine forests east of the Cascade crest in Washington State, primarily in Chelan and Douglas counties.[1] [2]
