From Wikipedia, the free encyclopedia
Euphyllophytina is an unranked taxon within the tracheophytes. It is sister to subdivision Lycopodiophyta. Euphyllophytina contains the two groups Spermatophytes (seed plants) and Monilophytes (ferns), as well as a number of extinct fossil taxa. The division of the extant tracheophytes into three monophyletic lineages is supported in multiple molecular studies[1][2][3].
