Abstract:

Lomatium swingerae R.P. McNeill is a new species described from one population on the Joseph Plains, between the Salmon River and Snake River, Idaho, U.S.A. It co-occurs with L. cous and is morphologically most similar to L. bicolor var. leptocarpum. It is easily distinguished from L. cous based on morphology of the ultimate segments, involucral bractlets and mericarps, and from L. bicolor var. leptocarpum based on habitat, overall size of the plant, structure of the primary and secondary umbels, the ultimate segments and phenology.
