Canyonlands Lomatium (Lomatium latilobum)

Description
  • Global Rank: G1 - Critically Imperiled
  • Legal Status: N/A
  • Family: Apiaceae
  • State: CO, UT
  • Nature Serve ID: 153286
  • Date Inducted in National Collection: 02/10/1987

Canyonlands biscuitroot, Lomatium latilobum, is found on the steep rocky talus created by collapse of the magnificent red sandstone cliffs and in fissures on slickrock. As such, the restricted acessibility of its habitat appears to be protecting this species from extinction (Spackman 1997). L. latilobum is a perennial herb that is a member of the Carrot Family. The pinnate leaves have 3-4 pairs of lateral leaflets. Besides attractive leaf masses, some individuals are strongly aromatic, with a lemon or anise scent. In April the flower produces five small yellow petals in clusters. When dying, the flower appears white. "Lomatium" is named from the Greek "loma for "bordered or fringed", referring to the conspicuous winged fruit. "Latilobum" comes from the shape of the leaf, meaning "broad lobes" (Utah Native Plant Society 2003-2007; Welsh et al. 1987; National Park Service).
