Arnica spathulata
''Arnica spathulata'' is a rare North American species of arnica in the sunflower family, known by the common name Klamath arnica.〔(Jepson Manual Treatment )〕 It is native to the Klamath Mountains of northwestern California (Humboldt, Trinity, Siskiyou, and Del Norte Counties) and southwestern Oregon (Curry, Josephine, Jackson, and Douglas Counties).〔(Biota of North America Program 2014 county distribution map )〕 It grows in woodland habitat, almost exclusively on serpentine soils.〔〔(Calflora taxon report, University of California, ''Arnica spathulata'' E. Greene, Klamath arnica )〕
''Arnica spathulata'' is a rhizomatous perennial herb producing one or more hairy, glandular stems 10 to 50 centimeters tall.〔 There are several pairs of broadly lance-shaped leaves along the stem, and a cluster of leaves about the base of the stem.〔 The basal leaves are up to about 15 centimeters long and the cauline leaves, those higher on the stem, are somewhat shorter.〔〔(Greene, Edward Lee 1896. Pittonia 3(15B): 103–104 )〕
The inflorescence holds many flower heads lined with phyllaries coated in long, white hairs.〔 The flower head is discoid, containing only yellow disc florets and none of the showier ray florets.〔 The fruit is an achene up to a centimeter long, not counting its white pappus.〔〔(Flora of North America Vol. 21 Page 376 Klamath arnica ''Arnica spathulata'' Greene )〕
