This data matrix contains only those positions of a complete alignment (not shown) that distinguish Californian from African Lepidium taxa. Californian and African species are extant members of two different lineages suggested to have been involved in the hybridogenous origin of Australian/NZ Lepidium species. R = A and G; W = A and T; Y = C and T; K = G and T; S = G and C. Site numbers are those of the complete alignment. For details see Mummenhoff et al. (2004).
