Oregon Bolandra from McCord Creek in the Columbia River Gorge..........May 2005.
Oregon Bolandra is a perennial with slender, erect or arching stems from 15-60 cm high. The herbage is glandular-hairy. The basal leaves are heart-shaped with shallow lobes which are further divided into small acute teeth. The leaves are thin, 3-7 cm wide, and have long slender petioles. The 2-4 stem leaves are reduced in size and have long stipules.
The inflorescence is a loose panicle with several side branchs,these each having 1-7 flowers. The calyx is globose at its base and narrowed above with a length of 5-8 mm. The 5 spreading petals are dark purple and linear in shape, and about equal in length to the calyx lobes.
Variety imnahaensis from northeastern Oregon has a panicle with longer branches that are more slender and diffuse than those of their western cousins. The calyx is also narrower with longer and more slender lobes.
Oregon Bolandra may be found on moist shady cliffs, often near waterfalls.
Oregon Bolandra may be found along thelower Willamette River, in the Columbia River Gorge and along the Snake and Imnaha Rivers in northeastern Oregon and adjacent Idaho.
In the Columbia River Gorge, it may be found between the elevations 100'-1600' between Crown Pt. and Hood River, OR.
