Madia sativa
Madia citrigracilis
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 citrigracilis occurs in northeastern California and northern Nevada. Small or young plants can be exceedingly difficult to distinguish morphologically from M. gracilis, which is one of two putative parental species suggested by J. Clausen et al. (1945) to have been involved in the hybrid (allopolyploid) origin of M. citrigracilis. Molecular data reinforce Clausen et al.’s hypothesis that M. citrigracilis is evolutionarily distinct from M. gracilis.
