Cladogram of recent Ephedra based on Bayesian analysis of five regions from the nuclear and chloroplast genomes (18S, 26S, ITS, rbcL, and rps4). Bayesian posterior probabilities are given above branches, parsimony bootstrap values below branches. Species marked * and ** were examined for papillae on the inner surface of apical part of the outer envelope. For species marked *, the DNA voucher material was investigated. For species marked **, other material has been used.
