Juniperus seravschanica

The most robust analysis of Iranian junipers utilized all our molecular data (cpDNA, nrDNA, 6 SCNGs). Figure 6 shows that J. excelsa , J. polycarpos , J. polycarpos var. turcomanica and J. seravschanica resolve into 4 groups. Juniperus excelsa , J. polycarpos , and J. seravschanica are in well supported clades ( Fig. 6 ). As previously mentioned, no samples of J. excelsa were found in Iran. It should be noted that, although all J. polycarpos var. turcomanica samples are grouped together, they are not in a distinct clade. This is because of the incongruence between their cpDNA and nuclear DNA, suggestive that this taxon is of hybrid origin. Putative J. seravschanica from Khabr, Kuhbanan and Rabor are clearly nested with typical J. seravschanica ( Fig. 6 ), and this supports the recognition of J. seravschanica as a distinct species in the flora of Iran. Putative J. polycarpos var. turcomanica from Bajgiran is in the group with J. polycarpos var. turcomanica from Turkmenistan ( Fig. 6 ).

Fifty percent majority rule consensus Bayesian tree based on nrDNA ITS, plastid petN-psbM, trnD-trnT, trnL-trnF,trnS-trnG intergenic spacers and single copy nuclear genes (LHCA4, maldehy, myb, CnAIP3 and 4CL) combined data. Numbers above branches are Bayesian posterior possibilities (before slashes) and maximum likelihood bootstrap support values (after slashes), while numbers under branches are maximum parsimony bootstrap support values. Values <50 % are not shown. CI= 0.813 RI= 0.938.
