“…Floral asymmetry is characteristic for some larger clades of Fabaceae, such as Senna and Chamaecrista in caesalpinioids, in which the flowers are more or less open but corolla, androecium and gynoecium (enantiostyly) can be involved in asymmetry (Tucker, 1996;Gottsberger & Silberbauer-Gottsberger, 1988;Marazzi et al, 2006Marazzi et al, , 2007Marazzi & Endress, 2008), and Delonix, in which the androecium base with the access to the nectar is asymmetric (Troll, 1951;Endress, 1994); in Papilionoideae the flowers of Phaseoleae are largely asymmetric by sometimes extensive torsion of the keel (Troll, 1951;Brizuela et al, 1993;Endress, 1994;Etcheverry et al, 2008), or in certain Vicieae the keel is asymmetric without torsion (the asymmetry arising late in development), as in Lathyrus species (Teppner, 1988;Westerkamp, 1993;Prenner, 2003) and Ottleya (Ottley, 1944;Sokoloff, 1999;Sokoloff et al, 2007); asymmetry in the androecium is present in early development of Fig. 6 Occurrence of different floral asymmetry patterns across angiosperms (cladogram from APG, 2003, with change of "Nymphaeaceae" to "Nymphaeales", to include Hydatellaceae, according to Saarela et al, 2007).…”

Floral monosymmetry and asymmetry are traced through the angiosperm orders and families. Both are diverse and widespread in angiosperms. The systematic distribution of the different forms of monosymmetry and asymmetry indicates that both evolved numerous times. Elaborate forms occur in highly synorganized flowers. Less elaborate forms occur by curvature of organs and by simplicity with minimal organ numbers. Elaborate forms of asymmetry evolved from elaborate monosymmetry. Less elaborate form come about by curvature or torsion of organs, by imbricate aestivation of perianth organs, or also by simplicity. Floral monosymmetry appears to be a key innovation in some groups (e.g., Orchidaceae, Fabaceae, Lamiales), but not in others. Floral asymmetry appears as a key innovation in Phaseoleae (Fabaceae). Simple patterns of monosymmetry appear easily "reverted" to polysymmetry, whereas elaborate monosymmetry is difficult to lose without disruption of floral function (e.g., Orchidaceae). Monosymmetry and asymmetry can be expressed at different stages of floral (and fruit) development and may be transient in some taxa. The two symmetries are most common in bee-pollinated flowers, and appear to be especially prone to develop in some specialized biological situations: monosymmetry, e.g., with buzz-pollinated flowers or with oil flowers, and asymmetry also with buzz-pollinated flowers, both based on the particular collection mechanisms by the pollinating bees. Floral monosymmetry has developed into a model trait in evo-devo studies, whereas floral asymmetry to date has not been tackled in molecular genetic studies.

Lotus comprises ca. 130 species of herbs, semishrubs and shrubs native to the Old World, including important pasture crops and a model legume, L. japonicus. Earlier nrITS‐based phylogenies were incongruent with all taxonomic classifications of the genus. In particular, members of the former genus Dorycnium were unexpectedly placed near species of L. sect. Lotus. The primary goal of the present study is to explore whether the unexpected placement of members of sect. Lotus and the former genus Dorycnium in earlier phylogenetic studies resulted from (1) insufficient taxon sampling and/or (2) the use of only one DNA marker. The rooting of the Lotus phylogeny, its major clades and basic biogeographic patterns are also discussed. This is the first global phylogenetic study of Lotus that uses both plastid and nuclear markers. The nrITS region was analyzed in 155 ingroup specimens representing 98 species of Lotus. Sequences of nrITS, nrETS, psbA‐trnH spacer and rps16 intron were analyzed for 70 ingroup specimens representing 54 species. The placement of the segregate genera Dorycnium and Tetragonolobus in the synonymy of Lotus was confirmed. Analyses of plastid data strongly supported a basal split of Lotus into two clades, one comprising species of sect. Lotus plus those traditionally placed in Dorycnium and the other including the rest of the species. The former clade has a centre of species diversity in Europe and N Asia, and the latter in Macaronesia, Africa and S Asia. Only the "Southern" clade is resolved in analyses of nrITS and nrETS data. Trees inferred from plastid, nrITS and nrETS data shared the occurrence of several smaller clades corresponding to traditionally recognized infrageneric taxa or species groups as well as the occurrence of some well‐supported clades that differ from traditional taxonomic concepts. Several instances of incongruence were documented between nuclear and plastid markers and between the two nuclear markers, possibly resulting from reticulate evolution. The extant geographic patterns of Lotus are likely biased by at least one round of area fragmentation followed by expansion coupled with extensive speciation associated with the complex history of the Mediterranean biome.
