Notes: FNA21: "Lagophylla ramosissima occurs widely in dry, often disturbed or poor soils of the California Floristic Province, Great Basin, and Pacific Northwest. Plants with heads in glomerate arrays have been treated as L. congesta or L. ramosissima subsp. congesta; W. C. Thompson (1983, p. 21) concluded that L. congesta represents an "extreme morphological variant of L. ramosissima" unworthy of taxonomic recognition."
