Conioselinum scopulorum (A.Gray) J.M.Coult. & Rose

An apiacid of moist montane coniferous forest, found in the Rocky Mountains and adjacent ranges. Conioselinum scopulorum is easily confused with Ligusticum porteri, but the two differ as follows: Conioselinum scopulorum has fruits that are dorsally compressed (flattened parallel to the commissure where the two carpels are connate) and has prominent, linear bracts in the involucel, the longer of which are about as long as the pedicels; Ligusticum porteri has fruits that are laterally compressed (flattened perpendicular to the commissure) and the involucel is absent or minute, with the bracts ca. 1/10 the length of the pedicels.
