Ecology & Habitat

Description

Nevada Bitterroot is a low, succulent, glabrous perennial with several leafless stems that are 1-8 cm high and arising from a fleshy, usually unbranched rootcrown. The numerous, linear-oblong basal leaves are up to 15 cm long and surpass the flower stems. There are 2 opposite, narrowly lance-shaped leaves surrounding the stem at mid-height, and there is a solitary flower on top. Each flower has 2 elliptic, pointed, entire-margined sepals that are 5-10 mm long, 5-9 white to deep pink petals that are 6-17 mm long, and 4-12 stamens. The fruit is a globose capsule with 1-5 dark brown seeds; it is about as high as the sepals.
