General information
Lomatium latilobum saddles the border of Colorado and Utah where it is found in Grand and San Juan Counties, Utah and Mesa County, Colorado. This species is often associated with pinyon-juniper, dwarf mountain mahogany and desert shrub communities and grows on sandstone. Canyonlands Lomatium is a leafy upright with a bouquet of tiny yellow flowers that bloom in a celebratory cluster on top of long flower stalks. The flowers produce a distinct array of long ridged and winged fruits at the end of each flowering season.

Phenology
Flowers April to June.
Diagnostic characteristics
Lomatium latiloboum has pinnate leaves in 3-5 pairs of lanceolate to elliptic leaflets. The leaflets are 1-4 cm long, 2-12 mm wide, or some always over 5 mm wide.
Species range
Navajo Basin endemic. Known from Grand and San Juan Counties, Utah, and Mesa County, Colorado.
Threats or limiting factors
Heightened interest in hiking the "fin" areas of Arches National Park and Behind the Rocks along with the influxes of mountain-bikers to the area has resulted in increased trampling and disturbance of the plant and its habitat. Also, the southern portion Behind the Rocks is apparently used heavily by cattle. May also be threated by exotic plants. Exotic plants present at one site include Bromus tectorum and Lepidium perfoliatum (EO data in the NatureServe central database as of July 2011).
