Madia sativa
Madia glomerata
In North America, Madia sativa occurs on the Pacific Coast from California to British Columbia, sporadically in coastal ranges, and rarely eastward. Reports of M. sativa from Ontario and Quebec and from Alaska, Connecticut, Georgia, Idaho, Indiana, Iowa, Maine, Maryland, Massachusetts, New York, North Carolina, Pennsylvania, Vermont, and Wisconsin are putative waifs or misidentified M. glomerata. Molecular data and greenhouse studies have indicated that plants referable to M. capitata and M. sativa in California are not distinct (B. G. Baldwin, unpubl.). Sampled populations of M. sativa (including M. capitata) from California are somewhat divergent in DNA sequences from sampled Chilean populations, in apparent conflict with earlier suggestions that M. sativa was recently introduced to North America from South America by Europeans (Baldwin, unpubl.). Madia sativa has been cultivated for seed-oil in South America, Europe, Africa, and Asia Minor (E. Zardini 1992).

Madia glomerata has the most extensive North American distribution of any species in Madiinae. At southern latitudes, M. glomerata occurs mostly in montane settings. Occurrences in eastern North America are mostly local and widely scattered.
