Skip to main content. Log In Sign Up. Lamiaceae International Journal of Plant Sciences, BoxNL RA Leiden, The Netherlands 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 Kalavryha data from GenBank, were conducted in order to assess the phylogenetic signal of palynological characters.
Salviinae pollen is small to large, oblate to Looking for sex glen Kalavryta 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 Kaalvryta, 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 phy- logenetic analyses show that the addition of palynological characters contributes to Looking for sex glen Kalavryta resolution Lady looking sex Bluewell also increases bootstrap support values in comparison with molecular phylogenetic analyses.
