Abstract: | A molecular phylogeny of the familyIridaceae based on the plastid generps4 was obtained using both parsimony and distance methods. Thirty-four species were examined together with eight outgroup species. Results show that theIridaceae are monophyletic, and thatIsophysis is likely to be the earliest emerging genus. SubfamilyIxioideae plus the generaAristea andNivenia form a strongly supported clade. Within subfam.Iridoideae, the tribeIrideae includes the genusBobartia (of disputed position), and the tribeMariceae includesCypella. The division ofIridoideae into tribes is consistent with their geographical distribution. |
