Abstract:

Lomatium basalticum Mansfield & M. Stevens, sp. nov., is a narrowly endemic species growing on gravelly meadows and open, xeric, rocky slopes in forest openings on weathered basalt flow entablatures on both the Idaho and Oregon sides of Hells Canyon. The species is most closely related to L. brunsfeldianum based on strong support from sequence data from 6 genes; and it is vegetatively very similar to the nearby northern Idaho endemic, L. brunsfeldianum. The two species can be distinguished geographically, ecologically and by a combination of characters including fruit length, width, and thickness, leaf sheath width, and foliage vestiture.
