| Taxonomy Comments: | Lomatium dissectum (Nutt.) Mathias & Constance (1942: 246) and L. multifidum have been treated as separate species and as varieties of a single species. The new combination is based on morphological differences, seasonal differences in fruit/flowering time, and limited geographic overlap of the taxa. In the few locations where the taxa co-occur, there are no individuals with intermediate morphological characteristics and there is distinct separation of the timing in fruiting and flowering. Lomatium multifidum occurs in shallow rocky soils, on slopes with a south aspect, or at lower elevations. Lomatium dissectum occurs in deep, mesic soils on slopes with a north aspect, or at higher elevation. Lomatium multifidum has yellow flowers, long pedicels, and glabrous peduncles, while L. dissectum has purple (rarely yellow with a purple tint) flowers with short pedicels, and glaucous peduncles. In addition, L. multifidum has already produced fruit while L. dissectum is still in flower (Feist et al., 2017). | ||||||||||
