Phylogenetic relationships in Selaginellaceae based on RBCL sequences [PDF]

American Journal of Botany, 2002
A phylogenetic framework is developed for the clubmoss family Selaginellaceae based on maximum parsimony analyses of molecular data. The chloroplast gene rbcL was sequenced for 62 species, which represent nearly 10% of living species diversity in the family.
