What is a genus of North American plants in the aster tribe within the daisy family, Sorbus or Townsendia ?
Sorbus Sorbus is a genus of about 100–200 species of trees and shrubs in the rose family Rosaceae. Species of "Sorbus" ("s.l.") are commonly known as whitebeam, rowan, service tree, and mountain-ash. The exact number of species is disputed depending on the circumscription of the genus, and also due to the number of apomictic microspecies, which some treat as distinct species, but others group in a smaller number of variable species. Recent treatments treat "Sorbus" in a narrower sense to include only the pinnate leaved species of subgenus "Sorbus", raising several of the other subgenera to generic rank.
Claytonia lanceolata Claytonia lanceolata is a species of wildflower in the Montiaceae family, known by the common names lanceleaf springbeauty and western springbeauty. This plant is native to western North America as far south as New Mexico where it grows in foothills up to alpine slopes. It thrives in the rocky soil of alpine climates where the snow never melts. It is a perennial herb growing from a tuber one to three centimeters wide. It produces a short, erect stem reaching a maximum height of 15 centimeters. At its smallest the plant bears only its first two rounded leaves before flowering and dying back.Its thick leaves are helpful for storing water. If it continues to grow it produces thick, lance-shaped leaves further up the stem. The star-shaped flowers come in inflorescences of three to 15 blooms and they are white or pink, often with veiny stripes and yellow blotches near the base of each petal. The fruit is a small capsule containing 2 seeds, which are black and shiny. The Okanagon-Colville, Okanagon, and Thompson Native American peoples used the tuber of this plant for food and for animal fodder.
