As a result, the rela- tionships among the taxa as well as the evolution of morphological traits have remained elusive and the traditional classifications are highly artificial. Using five molecular markers (nuclear ITS, plastid matK plus trnK, ndhF, trnL-trnF, psbA-trnH), we arrived at a phylogenetic hypothesis of this group, the genera Alcea, Althaea and Malvalthaea being studied here for the first time with molecular data. Althaea and, in particular, Lavatera and Malva are highly polyphyletic as currently circumscribed, because their diag- nostic characters, the number and degree of fusion of the epicalyx bracts, evolve in a highly homoplasious manner. In contrast, fruit morphology largely agrees with the molecularly delimited groups. Hybrid ori- gins confirmed for the genus Malvalthaea and for Lavatera mauritanica and hybridization in the group of ruderal small-flowered mallows underline the importance of reticulate evolution in shaping the history of this group and complicating the interpretation of morphological evolution.} }
