Artemisia ludoviciana Nutt. ssp. ludoviciana.  (Syn: A. britonii Rydb. ) White Sagebrush. CalPhotos. Jepson eFlora. SEINet Taxon.

Perennial herb, to 40 cm, unarmed, spreading by rhizomes; Leaf tomentose abaxially, sparse tomentose adaxially, proximal wedge-shaped, 40 mm × 15 mm wide, 3+-toothed, ≤⅓ leaf-width, distal lanceolate, entire (Described from Coll. No. 898, 24 August 2012, Frequency and depth of leaf lobing distinguishes between ssp. ludoviciana and ssp. incompta. These leaves are neither 2°-divided, nor deeper than ⅓-width, nor divided nearly to the mid-rib. Therefore, ssp. ludoviciana is applied rather than ssp. incompta).
