AB  - The vast majority of highly valuable species of the Leguminosae in temperate latitudes belong to the Inverted Repeat-Lacking Clade (IRLC). Despite having a generally conserved monosymmetric floral morphology, members of this group are remarkable with a pronounced diversity of floral sizes, modes of staminal fusion, and pollination strategies. This paper examined androecia and floral nectaries (FNs) in selected genera of the IRLC. External morphology was investigated using stereomicroscopy and scanning electron microscopy. In some cases, the pattern of staminal fusion was additionally examined in transverse sections using light microscopy. Androecia of all selected genera fell into one of four types, viz., monadelphous, pseudomonadelphous, diadelphous or diadelphous reduced (with inner stamens converted into sterile staminodes). However, there was significant variation in the stamens’ mode of contact, as well as the shape and size of the fenestrae providing access to FNs. Some types seemed to arise independently in different genera, thus providing a high level of homoplasy. FNs were more conserved and comprised areas of secretory stomata in the abaxial part of the receptacle and/or hypanthium. Nectariferous stomata could be found in very miniaturized flowers (Medicago lupulina) and could even accompany monadelphy (Galega). This indicates that preferential self-pollination may nevertheless require visitation by insects.

AB  - The largest genus of the diverse angiosperm family Lythraceae, Cuphea, is remarkable in having floral hexamery associated with monosymmetry. Although some aspects of floral morphology in Cuphea have been investigated to date, we examined floral ontogeny in two species of this genus in comparison with Lythrum salicaria, a member of the same family with hexamerous polysymmetric flowers. Scanning electron microscopy was applied to observe both floral development and morphology. In all three species, calyx initiates first, then the primordia of the outer stamens appear more or less simultaneously with the gynoecium, then the inner stamens and the corolla is the last to initiate. In the apetalous C. ignea, we found no signs of petal initiation. Flowers of L. salicaria can be either hexa- or pentamerous, sometimes with irregular merism, and they are less stable than those of Cuphea spp. in this respect. We classified two features of monosymmetry in Cuphea as ‘early’, viz. absence of initiation of the dorsalmost outer stamen and asynchronous initiation of carpels. The other features of floral monosymmetry in Cuphea appear later, these are unequal development of carpels, the adaxial position of disc, the monosymmetric placenta, and the unequal level of staminal insertion as well as the distribution of indumentum. The presence of (putative) secretory stomata on the disc confirms the hypothesis of its role as nectary. Our results evidence for the non-phyllome origin of the epicalyx in Lythraceae.
