“…Subtribe Salviinae consists of eight genera, and these genera have been classified differently according to various authors (table 1; Harley et al 2004).

However, the relationships among the genera of Mentheae are poorly understood (Harley et al 2004). Salvia is by far the largest genus of the family and represents a cosmopolitan assemblage of ca.…”

“…Until now, the presence of orbicules has not been investigated systematically in Lamiaceae (Huysmans et al 1998(Huysmans et al , 2000. Orbicules have been recorded only in Chloanthaceae (Raj and El-Ghazaly 1987; tribe Chloantheae of Lamiaceae sensu Harley et al 2004). Orbicules may also occur in Lavandula dentate L., which possesses a secretory tapetum (Suarez-Cervera and Seoane-Camba 1986), although this has yet to be confirmed.…”

The pollen morphology and ultrastructure of the subtribe Salviinae were investigated with light, scanning electron, and transmission electron microscopy. In addition, cladistic analyses of the obtained morphological data, supplemented with rbcL data from GenBank, were conducted in order to assess the phylogenetic signal of palynological characters. Salviinae pollen is small to large, oblate to prolate in shape, with a circular to slightly elliptic amb, and mostly hexacolpate. Perovskia abrotanoides appears to be distylous and shows a significant pollen dimorphism between pin and thrum flowers. The sexine ornamentation of the genera Lepechinia and Chaunostoma is perforate, while the ornamentation of other genera is bireticulate. Perovskia expresses a unique type of sexine ornamentation. The sexine ornamentation variation in Salvia has systematic importance but only partly corresponds with current phylogenetic hypotheses. Unbranched columellae and a continuous, granular endexine are hypothesized to be a symplesiomorphic condition in the tribe Mentheae. Our combined phylogenetic analyses show that the addition of palynological characters contributes to improved resolution and also increases bootstrap support values in comparison with molecular phylogenetic analyses.

Premise Fruit type and morphology are tightly connected with angiosperm diversification. In Boraginales, the first‐branching families, including Hydrophyllaceae, have one‐ to many‐seeded capsules, whereas most of the remaining families have four‐seeded indehiscent fruits. This fact argues for many‐seeded capsules as the ancestral condition. However, little is known about the evolution of fruit dehiscence and seed number. The present study investigated the gynoecium and fruit development and morphology and the evolution of seed‐numbers in Hydrophyllaceae. Methods Gynoecium and fruit development and morphology were studied using scanning electron microscopy and x‐ray microcomputed tomography. Ancestral character state reconstruction of seed number was performed using a broadly sampled phylogeny of Boraginales (ndhF and ITS) with an emphasis on Hydrophyllaceae. Results Our ontogenetic studies not only demonstrate parallel developmental trajectories across Hydrophyllaceae, but also a striking diversity regarding the internal organization of the gynoecium. Ovule number appears to determine ovary structure. Many‐seeded capsules are retrieved as the ancestral state of Hydrophyllaceae. At least seven transitions to fruits with (one to) four seeds and four reversals (i.e., from four‐ to many‐seeded fruits) were reconstructed in Hydrophyllaceae. Conclusions Several shifts in seed number from “many” to “four” and back to “many” have taken place in capsular‐fruited Hydrophyllaceae, a strikingly high number considering that seed number is virtually conserved across the rest of the order. The groups with a conserved seed number of four are characterized by indehiscent schizocarps or drupes and by seeds that are integrated into mericarps. This functional integration probably acts as an evolutionary constraint to shifts in seed number.
