Common Lomatium

Lomatium utriculatum is distributed in the far western part of North America from British Columbia to California; elevations of occurrence range from 50 to 1550 regions. Preferred habitats for this herb are open grassy slopes, meadows and woodlands.

Known as Common lomatium, this herb attains a height of ten to fifty centimeters. The plant taproot is slender, and its aboveground appearance is leafy. Petioles of leaves are 1.5 to 10.0 centimeters, with blade widths of five to sixteen centimeters; blade shapes are oblong to ovate, and the leaves are pinnately or ternate-pinnately dissected.
