Lomatium identification


By molecular studies, Lomatium and Cymopteris (and a few Tauschia and others) are extensively interdigitated, which appears not to have fully penetrated to formal naming. George et al 2014 Phylogenetic Analysis Reveals Multiple Cases of Morphological Parallelism and Taxonomic Polyphyly in Lomatium .

Crush some leaves and smell them! Hmm they all seem to smell of cedar and turpentine roughly.

Cymopterus terebinthinus - hmm except when fruiting looks a lot like a medium to big yellow Lomatium.
