Pale-yellow Jewel-weed - Impatiens aurella
State Rank Reason (see State Rank above)
Impatiens aurella is known from about 20 locations documented from 1886 to 2016. It is considered uncommon in Lake and Flathead Counties, where the majority of observations have been found, and rare in other counties of western Montana. It grows in wet, often organic soil in both disturbed and undisturbed wetlands, and rarely appears abundant. However, it may require or persist better with some hydrological disturbance. Revisits to known locations and more surveys are needed to better document locations, population sizes, and threats.
Stems erect, branched, 20–70 cm. Leaf blades 3–12 cm long; petioles 2–4 cm long. Flowers yellow, often with orange spots, 11–15 mm long; saccate sepal with a recurved spur 6–10 mm long. Capsule 1–2 cm long (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX)
